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.
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.
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.
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.
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.
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.
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.
Prozesse
(2012)
Für die effiziente Gestaltung des Leistungserstellungsprozesses im Un-
ternehmen bildet die Verwendung eines geeigneten Referenzmodells den
Grundstein, um in möglichst kurzer Zeit und ohne großen Aufwand ein
repräsentatives Abbild der konkreten Ablauforganisation zu generieren.
Als geeignetes Referenzmodell hat sich in diesem Anwendungszusam-
menhang das Aachener PPS-Modell bewährt. Dem als Prozess-
sicht bezeichneten Teil des Aachener Referenzmodells widmen sich die
folgenden Abschnitte des Kapitels im Besonderen.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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?
