Steigende Energiekosten sind ein zunehmendes Risiko für Unternehmen des deutschen Maschinen- und Anlagenbaus. Die Steigerung der Energieeffizienz kann somit zukünftig zu Wettbewerbsvorteilen führen. Aufgrund der Komplexität heutiger Produktionssysteme ist eine Analyse der Wechselwirkungen von Parametern der Produktionsplanung und -steuerung (PPS) auf die Energieeffizienz notwendig, um Maßnahmen zu identifizieren, die eine Steigerung der Energieeffizienz ermöglichen.
Der vorliegende Artikel stellt die Ergebnisse einer Simulationsstudie vor, in welcher der Einfluss der Losgrößenplanung auf die Energieeffizienz im Rahmen einer mehrstufigen Mehrproduktfertigung untersucht wird. Die Ergebnisse der Studie leisten einen Beitrag zum besseren Verständnis der komplexen Zusammenhänge und können als Ausgangspunkt für weitere Untersuchungen zu Wechselwirkungen von Produktionsparametern mit der Energieeffizienz dienen.
The growth of installed wind capacities generated a market with a huge variety of service offers for operation & maintenance of wind turbines. Different parties like manufacturers, component suppliers as well as independent service providers compete for the attractive after sales market. An innovative service offer which seems to meet the customers’ requirements is the guarantee of availability for wind turbines. However, these service providers are facing new challenges regarding their performance potentials and their financial risks occurring from possible penalties. Service providers have to reconsider their preparedness of performance, their new occurring financials risks, their cooperation and qualification level as well as their localization of service bases. To be able to quantify these new challenges and risks a simulation model has been designed in the context of a German research project named “WinServ”.
Service Engineering
(2016)
Für die Neuentwicklung von industriellen Dienstleistungen hat sich die Disziplin Service Engineering etabliert. Service Engineering umfasst die systematische Entwicklung von Dienstleistungen mithilfe ingenieurwissenschaftlicher und betriebswirtschaftlicher Methoden.
Aufbauend auf einer generellen Einführung und Definition werden im folgenden Kapitel die wesentlichen Zielsetzungen des Service Engineerings vorgestellt. Im Anschluss werden verschiedene Ansätze und Vorgehensweisen, die im Rahmen des Service Engineerings entwickelt wurden, betrachtet. Abschließend erfolgt die vertiefende Betrachtung verschiedener Methoden und Werkzeuge des Service Engineerings.
In most European countries a structural change from a production dominated towards a service oriented society is progressing. Companies increasingly consider services as means to gain competitive advantages in a global competition. In order to provide holistic, value-adding solutions while simultaneously guaranteeing high quality standards, production companies increasingly join forces with external services‘ providers. Models, methods and tools for service development are rare and in most cases immature. In the context of virtual services‘ development this leads to a dual set of simultaneous chal-lenges: an alignment of systematic services‘ and product development and the coordination of distributed R&D partners. The objective is to provide a meta-process that identifies all steps and decision points necessary to successfully develop innovative services. It is a result of combined service development and virtual enterprises‘/ networks‘ research.
Production in high-wage countries can be made more efficient, cost-effective, and flexible by solving the conflict between planning and value orientation. A promising approach is to focus on planning and decision-making processes (production planning and control, design of production processes and machinery, etc.) and to aim to maximize overall planning efficiency. Planning efficiency can be expressed as the ratio between the benefit generated by preparing detailed process instructions to produce the parts or components and the corresponding planning efforts. Industrial companies wanting to gain a competitive advantage in dynamic global markets have to identify a set of non-dominated solutions with the most favorable effort–benefit ratio rather than a single solution. The optimum between detailed planning and the immediate implementation of value-adding activities (process steps) in the process chain needs to be found dynamically for each product.
Today’s manufacturers are facing numerous challenges such as highly entangled and interconnected supply chains, shortening product lifecycles and growing product complexity. They thus feel the need to adjust and adapt faster on all levels of value creation. Self-optimization as a basic principle appears a promising approach to handle complexity and unforeseen disturbances within supply chains, machines and processes. Therefore it will improve the resilience and competitiveness of manufacturing companies.
This paper gives an introduction to the concept of self-optimizing production systems. After a short historical review, the different levels of value creation from supply chain design and management to manufacturing and assembly are analyzed considering their specific demands and needs for self-optimization. Examples from each of these levels are used to illustrate the concept of self-optimization as well as to outline its potential for flexibility and productivity. This paper closes with an outlook on the current scientific work and promising new fields of action.
Ziel des Forschungsbereichs "Selbstoptimierende Produktionssysteme" ist es, sowohl technische als auch soziotechnische Produktionssysteme zu entwickeln, die durch Selbstoptimierung eine bessere Performance erreichen, als bei der Auslegung geplant und erwartet werden kann. Im Fokus steht die Steigerung der Produktivität in der Produktion direkt vor Ort. Bedeutend ist die dezentrale Entscheidungsfähigkeit der Mitarbeiter auf dem Shopfloor und in unterstützenden Bereichen, sowie der kognitiven und adaptiven Systeme und Netzwerke in der Produktion.
Aus Sicht des Produktionsmanagements stellt die Beherrschung der steigenden Dynamik und den daraus resultierenden Konsequenzen wie beispielsweise Unter- und Überlastsituationen eine zentrale Herausforderung der kommenden Jahre dar. Ursachen der zunehmenden unternehmensinternen Dynamik sind verkürzte Lieferzeiten, eine höhere Prozessvarianz der Fertigung und Montage (verursacht durch individualisierte Produkte) und der Einsatz technologisch-komplexer Produktionsanlagen. Die drastische Verkürzung der Lieferzeiten hat die Auftragssituation und den Kapazitätsbedarf produzierender Unternehmen stark verändert.
Kapazitätsschwankungen und Prozessinstabilitäten einer Einzelressource wirken sich auf Grund der stärkeren Kopplung wesentlich drastischer auf die Stabilität des gesamten Unternehmens aus, da Bestände als Puffer zu kapitalintensiv geworden sind. Gleichzeitig nehmen makroskopische, überbetriebliche Kapazitätsschwankungen zu, da die Reaktionszeiten innerhalb der Lieferkette deutlich kürzer geworden sind.
Die steigende Varianz der Prozessketten und -zeiten potenziert die beschriebenen Kapazitäts- und Durchlaufzeitschwankungen. Eine "mittelwertbasierte PPS" kann aufgrund der gestiegenen Planungsanforderungen nicht mehr zielkonform agieren. Planungs- und Steuerungskonzepte, die auf diese Komplexität nicht reagieren können, multiplizieren ein weiteres Aufschwingen der Bedarfe in der Lieferkette und führen zu Auslastungsverlusten und steigenden Rückständen in der Produktion. Heute sind neue Ansätze in der Planung und Steuerung von inner- und überbetrieblichen Produktionsprozessen notwendig, die die Dynamik der Prozesse und der Kapazitätsbedarfe beherrschbar machen oder ggf. sogar kompensieren können.
Unternehmen sehen sich aktuell verschiedenen Herausforderungen ausgesetzt, die durch dynamische Rahmenbedingungen, insbesondere in Bezug auf die Schnittstellen zu ihren Kunden und Lieferanten, verursacht werden. Kundenseitig hat die zunehmende Individualisierung der Anforderung zu einem differenzierteren und damit vergrößerten Produkt- und Leistungsportfolio bei produzierenden Unternehmen im Rahmen der Serienfertigung geführt. Das hat zur Folge, dass Unternehmen ihre Produktion zunehmend auftragsbezogener gestalten müssen. In verschiedenen Branchen ist diese Entwicklung bereits so weit fortgeschritten, dass eine Produktvariante eins zu eins einem Kunden zugeordnet werden kann. Verstärkend kommt hinzu, dass die Produktlebenszyklen von allgemeinen als auch kundenindividuellen Produkten zunehmend kürzer werden. Das Produktportfolio unterliegt somit einer hohen Veränderlichkeit.
Die beschriebene zeitdynamische Variabilität in Bezug auf die qualitativen Aspekte der Kundenanforderungen paart sich mit einer quantitativen Variabilität der Kundenbedarfe. Letztere drückt sich in einem höheren Anteil an kurz- und mittelfristigen Auftragseingängen auf der Ebene einzelner Kunden, als auch aggregiert über alle Kunden aus. Die Vorhersehbarkeit und die Überraschung bilden die Extrempole des Kundenverhaltens, welche die Planbarkeit aus Sicht von Unternehmen induzieren. Damit kann in diesem Fall auch synonym von planbarem (vorhersehbarem/kurzfristigen) Kundenverhalten und nicht-planbarem (überraschendem) Kundenverhalten gesprochen werden. Diese Kombination qualitativer und quantitativer Variabilität macht den Markt für produzierende Unternehmen zunehmend schwerer kalkulierbar.
Zusammenfassend lässt sich herausstellen, dass Produktionsplaner heute komplexere produkt- und kundenseitige Anforderungen im Rahmen der Auftragseinlastung berücksichtigen müssen. Er muss darauf achten, dass Vertriebs-, Einkaufs-, Produktion- und Versandplanung miteinander synchronisiert werden, um den Kunden einen verbindlichen Liefertermin zusagen zu können.

Schlüsselfaktoren für den industriellen Einsatz Additiver Fertigung in produzierenden Unternehmen
(2020)
Die Additive Fertigung (AM) ist insbesondere als Hilfsmittel bei der Produktentwicklung weit verbreitet. 71 Prozent der produzierenden Unternehmen setzen AM für die Fertigung von Prototypen und Pilotserien ein. Derzeit eignet sich AM jedoch nicht mehr nur für die Fertigung von Prototypen und Pilotserien, sondern gewinnt auch zur Herstellung von Endprodukten aus metallischen Werkstoffen an Bedeutung. Der vorliegende Beitrag verfolgt das Ziel, Schlüsselfaktoren zu identifizieren, die den industriellen Einsatz von AM in produzierenden Unternehmen am stärksten prägen. Damit wird zugleich die Grundlage geschaffen für ein systematisches Vorausdenken der Zukunft.
Nowadays one of the most challenging tasks of producing companies is the growing complexity due to the globalization and digitalization. Especially in high wage countries, the ability to deliver fast and to a fixed date gets more and more important. To achieve this logistic target, it is necessary to optimize the Production Planning and Control (hereinafter PPC). This study investigates the effects of a change of the scheduling parameters on a target system. The focused research questions are: How can the effect of a scheduling parametersvariation on the target system of the PPC can be displayed efficiently? Is it possible to review the effect of the scheduling parameters-variation quantitatively and to derive action options?
Producing companies are confronted with a growing number of product ramp-ups, since product life cycles are decreasing and product diversity is increasing. Production Planning and Control (PPC) of ramp-up products is particularly challenging, as there is a significant lack of reliable experienced data.
The information deficit is exceptionally high for the first step of PPC process, namely Production Program Planning (PPP). The paper in hand proposes an innovative approach of cybernetic PPP that enables companies with numerous ramp-ups to design reliable and fast PPP processes that can react highly adaptable on unpredictable environmental disturbances. The Viable System Model (VSM) is used as frame of reference for the design of PPP processes in line with principles from management cybernetics.
Pricing is one of the most important, but underestimated tools, to enhance a company's profitability. Especially in the furniture sector, customers place a special interest in cost-efficient products and easy processes. Individualised and sustainable furniture can help to create a unique selling point and deliver real value to the customers. Therefore, a platform to create designs together is needed and can involve several stakeholders in the design and production phase. However, in order to include several stakeholders, the pricing and revenue model need to reflect individual needs and be a benefit to all. In this paper, the initial situation and potential revenue model options will be presented. Furthermore, multiple scenarios for practical use will be discovered and an overview given.
Ressourcen sind die Grundlage eines jeden Wertschöpfungsprozesses. Aus einer strategischen Perspektive können nur schwer imitierbare und einzigartige Kernkompetenzen die Grundlage eines langfristigen und nachhaltigen Wettbewerbsvorteils begründen. Demzufolge sind Ressourcen so auszuwählen, verfügbar zu machen sowie zu kombinieren, dass entsprechende Kompetenzen und Kernkompetenzen entwickelt werden. Dies ist die Aufgabe des strategischen Ressourcenmanagements. Allerdings unterscheiden sich die Auswahl und der Einsatz von Ressourcen zwischen Sachgütern und Dienstleistungen erheblich. Während bei Sachgütern die verwendeten Rohstoffe und Materialien oder die Produktionsbedingungen wesentliche Grundlage für die Qualität des Endprodukts sind, stehen bei Entwicklung, Vermarktung und Erbringung von Dienstleistungen die Mitarbeiter wesentlich stärker im Mittelpunkt. Daher stellt das Human-Resource-Management (HRM) den zentralen Ansatz für das Ressourcenmanagement industrieller Dienstleister dar. Aufgabe des HRMs ist es, die Mitarbeiter für die Entwicklung, Vermarktung und Erbringung von industriellen Dienstleistungen zu befähigen.
The complexity and volatility of companies’ environment increase the relevance of disruption preparation. Resilience enables companies to deal with disruptions, reduce their impact and ensure competitiveness. Especially in the context of procurement, disruptions can cause major challenges while resilience contributes to ensuring material availability. Even though past disruptions have posed various challenges and companies have recognized the need to increase resilience, resilience is often not designed systematically. One major challenge is the number of potential measures to increase resilience. The systematic design of resilience thus requires a detailed understanding of domain-specific measures. This also includes an understanding of the contribution of these measures to different resilience components and their interdependencies. This paper proposes a systematic approach for configuring resilience in procurement which enables the evaluation and selection of resilience measures. Based on a resilience framework, a resilience configurator is developed. The basis of the configurator are resilience potentials that have been characterized and clustered. Overarching approaches to design resilience and indicators to evaluate resilience are presented. Moreover, a procedure is proposed to ensure practical applicability. To evaluate the results two case studies are conducted. The results enable companies to systematically design their resilience in procurement.
In the near future, tooling companies will offer their customers not just maintenance services, but complex remote service packages for their engineering asset management, which is the total management of physical – not financial – assets. The overall goal is to enhance the efficiency of the engineering asset, e.g. to reduce TCO, on the customers´ site by means of value creating partnerships. These partnerships may be, e.g. the classical output or reliability partnership, but also process optimizing partnerships or lifecycle partnerships. The process optimizing partnership offers, e.g. the optimization of the system’s performance or the output quality, an optimized ramp-up and restart procedure or optimization of the production process parameters. The lifecycle partnership, on the other hand, accompanies the intelligent tool-machine-system throughout the whole lifecycle, which includes, e.g. provision of spare parts during the entire usage phase, storing, refurbishment, recycling and even the support of relocation of production facilities. Intelligent remote services have great potential for realizing all these partnerships.
To realize such engineering asset-related partnerships, two major tasks have to be done. First, there has to be the intelligent tool-machine system, which delivers the information that is required for these services. And furthermore, this information has to be integrated into the maintenance processes, so that it is delivered at the right place and time and in the required form. Second, the activities and processes that are combined to the engineering asset-related partnerships have to be configured out of standardized service and process modules. Therefore configuration logic is essential.
One of the major tasks of operations managers is to boost uptime while simultaneously keeping budget. To meet this challenge they discover reliability-based management as strategic factor to improve performance. But which parameters are the key to “reliability excellence” and drive a company’s performance? What are the relevant levers to pull in reliability-based management?
To answer these questions McKinsey & Company partnered with Aachen University to launch a global reliability survey in process industries. Objective of the initiative is to provide a statistically proven picture of key factors that drive maintenance and reliability excellence. Furthermore benchmarks and best practices concerning overall operational performance will be identified. The study is based on a questionnaire-based approach which addresses all relevant departments within a company, complemented by best practice analyses.
This paper provides results of the survey. The results demonstrate that reliability pays off. Some unproven beliefs have been confirmed (e.g. a good reliability performance results in a low spare part inventory) but also surprises like a correlation between safety and performance were identified. The analysis also shows that structural differences like company size or geography do not influence reliability performance.
Die Variantenfließfertigung ermöglicht die Herstellung konfigurierbarer Produkte bei kurzen Durchlaufzeiten und geringen Beständen. Im Vergleich zu anderen Organisationsformen der Produktion gestaltet sich die Produktionsplanung und -steuerung aufgrund der Variantenvielfalt als anspruchsvoll. Im vorliegenden Beitrag wird der erste Schritt einer Methodik vorgestellt, welche für die Konfiguration der Reihenfolgeplanung entwickelt wurde.
Competitive differentiation in the manufacturing sector is no longer based on product and service innovations alone but on the ability to monetize the usage phase of products and services. To this end, manufacturers are increasingly looking at so-called subscription business models as a way of supplementing the traditional sale of products and services. Since supplier success in the subscription business is directly dependent on customer success, the setup and expansion of a so-called Customer Success Management (CSM) is required. While CSM has already been established in the software industry for several years, companies in the manufacturing sector are often still in the conceptual phase of a CSM, parallel to the setup and expansion of their subscription business. Therefore, this paper aims to support the set-up of a CSM by providing a reference data model, based on case study research, that can be used to support the organizational or daily CSM tasks and to serve as a blueprint for conceptualizing CSM-specific IT systems.
Rebound Logistics
(2009)
Today, the flow of product returns is becoming a significant concern for many manufacturing companies. In this research area, three fundamental aspects of product returns need to be taken into consideration: First, companies become increasingly aware of the fact that product returns may offer an opportunity for enormous profit generation and for improving the competitive advantage of a manufacturing company when taking into account the accretive value of the products and technology. Second, the impact of green laws, legislative provisions and the increasing impact of a sustainable production management due to marketing aspects force companies to design and manage the reverse supply chain actively. Third, the importance of managing the reverse supply chains effectively will be enforced by the currently volatile economic climate. This paper outlines first results of designing a methodological framework for implementing an integrative reverse supply chain for manufacturing companies based on a type-specific Reverse Supply Chain Reference Model.
Production systems are exposed to an increasing planning-related uncertainty and susceptibility. The inter-company coordination has not sufficiently been considered in contemporary concepts of supply chain management. Against this background, it is crucial to provide a suitable tool that increases the planning capability of the players and the robustness of the supply chain as a whole. Therefore, this article provides the relevant causes and effects of planning uncertainties within the production planning and presents based on that an inter-company supply chain planning concept.
Manufacturing companies of the machinery and equipment industry find themselves more than ever exposed to a rapidly changing competitive environment. In particular, the resulting diversity of planning and control processes confronts organisations and information systems with a significant coordination effort. To this day, planning and execution of order processing – from offer processing to the final shipment of the product – is still a part of the production planning and control (PPC), which is almost entirely integrated into information systems. Though, in order to manage dynamic influences on processes within order processing, there can be found a deficiency in the processing of decision-relevant and real-time information. Partly, the reason for this is a missing or incorrect feedback of process relevant data, so that the planning results, gained by the use of information systems, differ to the current process situation.
The concept of Manufacturing Resource Planning (MRP II) still represents the central logic of production planning and control. However, the centralised and push-oriented MRP II planning logic is not able to plan and measure dynamic processes adequately, which, due to diverse disturbances, often occur in production environments. Furthermore, specific weaknesses of MRP II-based systems are the lack of support for order releases, the planning principle based on average values and the successive planning method as well as the use of limited partial models. As a result a successive planning method leads to a dissection of PPC-tasks into smaller work packages and so strides away from a holistic approach and the achievement of an optimal solution. Similarly, a planning, focusing on a general business objective system, using a partial planning approach due to isolated considerations is not possible. Insufficient consideration of the current load horizon and the current capacity utilization, non-existing or delayed feedback on order progress as well as faults and poor availability and transparency of information can be named as further weaknesses of MRP II-based systems.

With the development of publicly accessible broker systems within the last decade, the complexity of data-driven ecosystems is expected to become manageable for self-managed digitalisation. Having identified event-driven IT-architectures as a suitable solution for the architectural requirements of Industry 4.0, the producing industry is now offered a relevant alternative to prominent third-party ecosystems. Although the technical components are readily available, the realisation of an event-driven IT-architecture in production is often hindered by a lack of reference projects, and hence uncertainty about its success and risks. The research institute FIR and IT-expert synyx are thus developing an event-driven IT-architecture in the Center Smart Logistics' producing factory, which is designed to be a multi-agent testbed for members of the cluster. With the experience gained in industrial projects, a target IT-architecture was conceptualised that proposes a solution for a self-managed data-ecosystem based on open-source technologies. With the iterative integration of factory-relevant Industry 4.0 use cases, the target is continuously realised and validated. The paper presents the developed solution for a self-managed event-driven IT-architecture and presents the implications of the decisions made. Furthermore, the progress of two use cases, namely an IT-OT-integration and a smart product demonstrator for the research project BlueSAM, are presented to highlight the iterative technical implementability and merits, enabled by the architecture.
Produktionsprogrammplanung
(2014)
Ziel der Produktionsprogrammplanung ist es, einen hinsichtlich Absetzbarkeit und Realisierbarkeit abgestimmten Produktionsplan über einen langfristigen Planungszeitraum zu erstellen. Dieser Produktionsplan legt verbindlich fest, welche Erzeugnisse durch das Unternehmen in welchen Stückzahlen zu welchen Zeitpunkten bzw. in welchen Perioden produziert werden sollen. Teilaufgaben der Produktionsprogrammplanung sind die Absatzplanung, die Primärbedarfsplanung und die Ressourcengrobplanung. In diesem Kapitel werden zunächst die Kernaufgaben der Produktionsprogrammplanung definiert und anschließend die wesentlichen Methoden und Verfahren zur Bearbeitung der verschiedenen Teilaufgaben innerhalb der Produktionsprogrammplanung zusammengestellt. Abschließend werden die Aufgaben der Produktionsprogrammplanung in ihrer zeitlogischen Abfolge in Form eines Referenzprozessmodells modelliert und dabei fertigungstypspezifisch detailliert.
Ein ständig wachsender Preisdruck und immer individuellere Kundenaufträge sind nur zwei Kennzeichen der industriellen Produktion im europäischen Wirtschaftsraum. Gerade in Deutschland ansässige Unternehmen können im internationalen Wettbewerb in den wenigsten Fällen allein aufgrund des Produktpreises konkurrenzfähig bleiben. Stattdessen bauen diese Unternehmen ihre Wettbewerbsvorteile anderweitig aus und verfolgen vielmehr eine konsequente Kundenorientierung, hohe Logistikleistung oder Prozessbeherrschung. In diesem Umfeld setzten zahlreiche Unternehmen bereits frühzeitig auf eine Reduzierung ihrer Wertschöpfungstiefe und verlagerten verschiedene Entwicklungs- oder Produktionsschritte auf andere Unternehmen mit komplementären Kompetenzen. Damit rückte die überbetriebliche Zusammenarbeit bzw. Koordination der Auftragsabwicklung entlang einer mehrstufigen Lieferkette oder innerhalb eines polyzentrischen Unternehmensnetzwerks zunehmend in den Mittelpunkt betrieblicher Anstrengungen. So gilt es also heute, in Netzwerkstrukturen zu denken, diese ganzheitlich zu gestalten und effizient zu organisieren. Der Beitrag konkretisiert am Beispiel des Aachener PPS-Modells geeignete Referenzmodelle und zeigt Entwicklungspfade einer wertorientierten Logistikgestaltung auf.
Die Erfüllung der klassischen Aufgaben der Produktionsplanung und -steuerung (PPS) wird aufgrund der dynamischen Anforderungsprofile, die es Unternehmen abfordern, sich strukturell und operativ kontinuierlich zu verändern, zunehmend schwieriger. Der Umgang mit Dynamik und Komplexität wird vom Störfall zum Normalfall.
Vor diesem Hintergrund wird ein innovativer Ansatz für eine Produktionsplanung und -regelung vorgestellt, der das Ziel verfolgt, die den Produktionssystemen inhärente Planungskomplexität beherrschbar zu machen.
Der Lösungsansatz basiert auf kybernetischen Strukturen, die den Beschränkungen der Wandlungs- und Lebensfähigkeit. Als grundlegender Teil des Ansatzes wird die Produktionsregelung unter Berücksichtigung des Echtzeitaspektes entworfen.
Industrie 4.0 bringt enorme Veränderungen und bietet große Verbesserungspotenziale für die Produktionsplanung und -steuerung. Aufbauend auf dem Aachener PPS-Modell wird in diesem Beitrag in Anlehnung an den Industrie-4.0-Maturity-Index der acatech eine reifegradbasierte Untersuchung der Entwicklung der Produktionsplanung und -steuerung im Kontext von Industrie 4.0 präsentiert.
Produktionsbedarfsplanung
(2014)
Die Eigenfertigungsplanung und -steuerung erhält als Eingangsinformation das zu realisierende Eigenfertigungsprogramm aus der Produktionsbedarfsplanung. Das Ziel der Eigenfertigungsplanung und -steuerung ist die Erstellung, Umsetzung und Kontrolle eines detaillierten Ablaufplans für die Fertigung und Montage unter Berücksichtigung der tatsächlich verfügbaren Produktionsressourcen.
Zunächst werden die Kernaufgaben der Eigenfertigungsplanung und -steuerung definiert, abschließend werden die Aufgaben in Form eines Referenzprozessmodells modelliert.
Das (volks-)wirtschaftliche Umfeld produzierender Unternehmen wird aktuell mehr denn je durch unvorhersehbare und tiefgreifende Veränderungen geprägt. Die deutsche Industrie muss die Dynamik zukünftig aus eigener Kraft beherrschen. Teilweise nachteilige Standortfaktoren müssen kompensiert werden, um die Produktion in Deutschland langfristig zu sichern. Wandlungs- und Echtzeitfähigkeit in Prozessen und Strukturen stellen die zentralen Enabler zur Beherrschung des Produkt-Produktionssystems dar.
Pricing for Smart-Product-Service-Systems in Subscription Business Models for Production Industries
(2021)
In the production industry, subscription business models have the potential to create long-term relationships where a supplier provides a continuous value-oriented service to a customer based on digitalisation. Monetising this increase in value through pricing represents a central challenge for suppliers in subscription business. Unlike the current dominant transactional business, the focus of pricing is on the value-in-use of the customer (e.g. on the increase in output for the customer). In this regard, there is so far no pricing approach for practice that allows the linking of the performance data of the customer with the periodically charged price. However, in subscription businesses, such an approach is required to create win-win situations for the customer and supplier through continuous performance improvement. Therefore, this paper develops a novel process model for pricing of smart-product-service-systems in subscription business for production industries. This process can serve as basis for suppliers of subscriptions in the production industry to align pricing with the created value-in-use. In the long term, this allows companies to systematically develop their pricing to monetise the potential of digitalisation.
The importance of social networks and, in particular, enterprise social networks in business contexts is increasing significantly. Regarding the prerequisites for a successful implementation of an enterprise social network, exclusively providing the technical infrastructure is insufficient. A holistic view that considers and integrates different perspectives is crucial for success. This includes technological, organisational and human aspects as equally important parts of the network. This paper identifies prerequisites for a successful launch of enterprise social networks and groups them along these three dimensions.
Aktuell ist noch nicht geklärt, wie sich das Zusammenwirken von Menschen und betrieblichen Anwendungssystemen bei der Bearbeitung der Aufgaben der PPS nach der Umsetzung von Industrie 4.0 entwickelt. Zur Systematisierung der Auswirkungen von Industrie 4.0 auf die PPS werden in diesem Beitrag die sechs Reifegradstufen des acatech Industrie-4.0-Maturity-Index mit der Aufgabensicht des Aachener PPS-Modells kombiniert und die Reifegradstufen für ausgewählte Unteraufgaben der PPS spezifiziert.
PLM trifft ERP
(2013)
Subscription business transforms traditional business models of machinery and plant engineering. Many manufacturing companies struggle to pull out the potential created by Industry 4.0 and make it economically usable. In addition to technological innovations, it is necessary to transform the business model. This leads to a shift from ownership-based and product-centric business models to outcome-based business models, which focus on the customer's value and thus realize a unique value proposition and competitive advantage – the outcome economy. Based on a case study analysis among manufacturing companies, this paper provides further clarification including a definition and constituent characteristics of subscription business models in machinery and plant engineering.
One of the major challenges facing today´s manufacturing industry is to differentiate from competition in a highly globalized world. As a consequence to the increasing competitive pressure, many companies transform their product centered business models towards service based business models to differentiate from competition. However, the transformation is often underestimated regarding its complexity and its management challenges to behavioral change.
As a consequence lots of transformation initiatives fail. Besides difficulties in structuring the magnitude of changes in processes and structures, many transformation managers do not perceive the risk of employee resistance against changes, which is one of the key factors causing the failure of transformation. The objective of this paper is to enhance the existing body of research on manufacturer´s organizational transformation towards Product-Service Systems. More detailed, the objective is to develop new knowledge to support the management during the decision-making process in the way how and by means of which instruments the change of behavior can be supported when transforming from a manufacturer to a solution.
We developed a reference framework which structures and defines the relevant dimensions of behavioral change. The identification and validation of the success factors build the second component of our research. We conducted an empirical investigation in the German manufacturing industry and got 79 data sets.
Structural equation modelling was applied for the analyses and the validation of the hypotheses. By this analysis we linked management practice with employee behavior and transformational success variables. On the basis of the gained insights decisions can be made concerning the successful transformation from manufacturer to a solution-oriented service provider.
Im Zuge der fortschreitenden Angebotserweiterung um industrielle Dienstleistungen und immer komplexere Leistungssysteme sehen sich Industriegüterunternehmen vor der Herausforderung, ihre Organisationsstrukturen um- oder sogar neu zu gestalten. Neben der Auflösung der stark produktorientierten und häufig hierarchischen Organisationsstrukturen ist die Einführung von Center-Konzepten oder sogar unabhängigen Dienstleistungsbereichen zu einem Erfolgsgaranten für das Dienstleistungsgeschäft geworden.
In diesem Beitrag werden, aufbauend auf den generischen Formen der Unternehmensorganisation, verschiedene Möglichkeiten zur Einbindung der Dienstleistungseinheiten in das Unternehmen vorgestellt und vor dem Hintergrund der verschiedenen Entwicklungsstufen des Dienstleistungsgeschäfts diskutiert. Im Anschluss werden die verrichtungsorientierte und objektorientierte Gliederung für die Ausgestaltung der Dienstleistungseinheiten vorgestellt. Abschließend werden die verschiedenen Auftragsformen und der Umfang des Leistungsangebots als Einflussfaktoren der Organisationsstrukturierung diskutiert.
Mit der steigenden Bedeutung von industriellen Dienstleistungen und den damit verbundenen Herausforderungen der Unternehmensführung bedarf es eines Bezugsrahmens für das Management industrieller Dienstleistungen. Ein solcher Ansatz, der eine umfassende Beschreibung der Aufgaben des Managements darlegt, wurde von Schuh und Gudergan entwickelt.
Ziel des Ordnungsrahmens ist es, dem Management eine grundlegende Orientierung zu geben und dabei die relevanten Gestaltungsbereiche zu betrachten. Es wird in Anlehnung an das St. Galler Management-Modell zwischen einer internen und einer externen Perspektive unterschieden.
Der im weiteren Verlauf vorgestellte Ordnungsrahmen beschreibt den Betrachtungsbereich sowie Inhalte und Aufgaben, die für das Management Industrieller Dienstleistungen von Relevanz ist. Gleichzeitig ermöglicht der vorgestellte Ordnungsrahmen die Strukturierung und Einordnung der verschiedenen Themenfelder. Der Ordnungsrahmen gliedert dabei das Management industrieller Dienstleistungen in die Teilbereiche Unternehmensstruktur, Unternehmensprozesse und Unternehmensentwicklung. Diese innerbetrieblichen Aspekte werden in den Kontext der für das Unternehmen relevanten Umweltsphären und Anspruchsgruppen gesetzt.
Working capital management is one of the key disciplines that must be prudently monitored for a firm in pursuit of profits, liquidity and growth. The focus of this paper is on the engineer-to-order manufacturers, and the objective is to analyze the correlations between the reference processes of the engineer-to-order production approach with the key postulates of working-capital management and deliver a mathematical operating curves model, whose purpose and goal is basing on the rationale, that is underlying in the parent logistic operating curves theory.

Nowadays, cyber physical systems support the improvement of efficiency in intralogistics by controlling and manipulating the production and logistic environment autonomously. Due to the complexity of the individual production processes, designing suitable cyber-physical systems based on their existing production environment is a challenge for companies.
This paper presents a new methodology on how to design cyber-physical systems conceptually to suit an individual production environment. Compared to existing design approaches, this methodology matches immediately the required functions to existing information and communication technology’s components insisting on the neutral assimilation of requirements.
Therefore, the requirement specification asks for needed functions in relating to offered functions of information and communication technology (ICT) components. The paper focusses the use case of implementing a cutting-edge mobile network technology into an existing tracking and tracing process.
The design of data-driven industrial services in the context of industry 4.0 represents a major challenge for industrial service providers and manufacturing companies for investment goods. Data-driven services require technological and strategic components that most companies have not build up yet and that differ from current configurations. That is why many companies lack a systematic approach and implementation competence for the use of data in the context of industrial services and therefore face the challenge of not being able to expand their market position in an ever-growing competition for data.
The present paper addresses this research deficit with the aim of describing strategic features and characteristics of data-driven industrial services by identifying the related crucial features and characteristics through a morphological approach. This will enable industrial service providers to improve strategic and operative management decisions in order to define a specific strategy and to configure data-driven services.
Monetizing Industry 4.0: Design Principles for Subscription Business in the Manufacturing Industry
(2019)
Subscription business models have a major role for monetizing products and services for manufacturing companies in the age of Industry 4.0. As the manufacturing industry has difficulties generating revenues through digitalization, the implementation of innovative business models are essential to remain successful. Physical assets are often capital-intensive and require a more complex manufacturing process than subscription business models. Moreover, subscription models can focus on the individual customer benefit and a consistent service transformation, constituting a unique selling proposition and a competitive advantage. Hence, the following paper provides a management model that enables manufacturing companies to successfully realize the transformation towards a subscription business model. The management model presents four major fields of action, each matched with one design principle that must be considered when dealing with subscription models in the manufacturing industry. These principles were determined by an in-depth case study analysis among various manufacturing companies. Opportunities, challenges and recommendations for action were then systematically derived and integrated into the management model.
Due to shorter product life cycles the number of production ramp-ups is increasing, while customers have a soaring demand for more variable and individualized products. In the future, optimizing the production ramp-up will become an important differentiation criterion for companies. Considering the whole supply chain in the ramp-up process becomes therefore indispensable. This is what the presented research in this paper concentrates on. The intention of the research project is to develop a model of a supply chain in the production ramp-up stage. Through this model, approaches for optimizing the production ramp-up in the whole supply chain will be derived.
Further the research project concentrates on measuring the production ramp-up performance in the supply chain, showing the impact on economic and financial measures. The result of this research is an approach to align the tasks and objectives of Supply Chain Management with the tasks and objectives of ramp-up management in order to optimize the whole supply chain in the ramp-up stage.
Mobilität in NRW neu denken
(2018)
Ongoing digitalization and Industry 4.0 enable the development of new business models due to the increase in available data and digital connected products. A promising business model type for the machinery and plant engineering industry are subscription models, consisting of products and services offered in return for continuous payments. However, subscription-based business models are associated with extensive changes in the traditional machinery and plant engineering industry, in particular, for small and medium-sized companies (SMEs). Established concepts for the development of value propositions and business models neglect important aspects, such as the integrated development and optimization of products and services across the entire life cycle or the data infrastructure. This paper presents a concept for a methodology to support SMEs developing value propositions within subscription models. Therefore, the systematic identification of customer benefits, the determination and prioritization of subscription relevant functionalities as well as the design of product and service elements addressing those functionalities are the main aspects on which the focus is placed on. The result is a subscription value proposition canvas for SMEs to address the impact of subscription models on products and services.
Long-term production management defines the future production structure and ensures the long-term competitiveness. Companies around the world currently have to deal with the challenge of making decisions in an uncertain and rapidly changing environment. The quality of decision-making suffers from the rapidly changing global market requirements and the uniqueness and infrequency with which decisions are made. Since decisions in long-term production management can rarely be reversed and are associated with high costs, an increase in decision quality is urgently needed. To this end, four different applications are presented in the following, which support the decision process by increasing decision quality and make uncertainty manageable. For each of the applications presented, a separate digital shadow was built with the objective of being able to make better decisions from existing data from production and the environment. In addition, a linking of the applications is being pursued:
The Best Practice Sharing App creates transparency about existing production knowledge through the data-based identification of comparable production processes in the production network and helps to share best practices between sites. With the Supply Chain Cockpit, resilience can be increased through a data-based design of the procurement strategy that enables to manage disruptions. By adapting the procurement strategy for example by choosing suppliers at different locations the impact of disruptions can be reduced. While the Supply Chain Cockpit focuses on the strategy and decisions that affect the external partners (e.g., suppliers), the Data-Driven Site Selection concentrates on determining the sites of the company-internal global production network by creating transparency in the decision process of site selections. Different external data from various sources are analyzed and visualized in an appropriate way to support the decision process. Finally, the issue of sustainability is also crucial for successful long-term production management. Thus, the Sustainable Footprint Design App presents an approach that takes into account key sustainability indicators for network design.
