Local implementation projects for sector coupling play an important role in the transformation to a more sustainable energy system. Despite various technical possibilities, there are various barriers to the realisation of local projects. Against this backdrop, we introduce an inter- and transdisciplinary approach to identifying and evaluating different power-to-X paths as well as setting up robust local implementation projects, which account for existing drivers and potential hurdles early on. After developing the approach conceptually, we exemplify our elaborations by applying them to a use case in the German city of Wuppertal. It can be shown that a mix of several interlinked interdisciplinary methods as well as several participatory elements is suitable for triggering a collective, local innovation process. However, the timing and extent of end-user integration remain a balancing act. The paper does not focus on a detailed description of power-to-X (PtX) as a central pillar of the sustainable transformation of the energy system. Rather, it focuses on the innovative methodological approach used to select a suitable use path and design a corresponding business model. The research approach was successfully implemented in the specific case study. However, it also becomes clear that the local-specific consideration entails limitations with regard to the transferability of the research design to other spatial contexts.
In the age of digitalization, manufacturing companies are under increased pressure to change due to product complexity, growing customer requirements and digital business models. The increasing digitization of processes and products is opening up numerous opportunities for mechanical engineering companies to exploit the resulting potential for value creation. Subscription business is a new form of business model in the mechanical engineering industry, which aims to continuously increase customer benefit to align the interests of both companies and customers. Characterized by a permanent data exchange, databased learning about customer behavior, and the transfer into continuous innovations to increase customer value, subscription business helps to make Industry 4.0 profitable. The fact that machines and plants are connected to the internet and exchange large amounts of data results in critical information security risks. In addition, the loss of knowledge and control, data misuse and espionage, as well as the manipulation of transaction or production data in the context of subscription transactions are particularly high risks. Complementary to direct and obvious consequences such as loss of production, the attacks are increasingly shifting to non-transparent and creeping impairments of production or product quality, which are only apparent at a late stage, or the influencing of payment flows. A transparent presentation of possible risks and their scope, as well as their interrelationships, does not exist. This paper shows a research approach in which the structure of subscription models and their different manifestations based on their risks and vulnerabilities are characterized. This allows suitable cyber security measures to be taken at an early stage. From this basis, companies can secure existing or planned subscription business models and thus strengthen the trust of business partners and customers.
The digital transformation is changing the way companies think and design their manufacturing environment. Both due to the increasing number of connections between IoT-Devices, tooling machines, and production lines and the phenomenon of the convergence of IT and OT, systems are becoming more complex than years ago. Organizational and cultural changes within manufacturing companies strengthen this trend and form Industry 4.0 environments and cyber-physical production systems (CPPS). As these systems do not longer stay alone but are connected to each other and the company’s outside, the size of the potential attack surface is increasing as well. Besides that, manufacturing companies, small and medium-sized in particular, are facing complex challenges based on lack of knowledge, budget, and time to understand as well as to interpret their current situation and risk level and therefore to derive necessary counter-measures. Efficient as well as pragmatic tools and methods for these companies do not exist. This paper shows a research approach in which the company-specific set-up of Industry 4.0 environment and CPPS is characterized by its potential vulnerabilities. This enables companies to evaluate their risk potential before setting up this kind of environments and to undJo,erstand the potential consequences more precisely. By doing so, companies can derive and prioritize important counter-measures and so to strengthen their level of cyber-security efficiently. This will decrease the number of cyber-security attacks and increase the company’s competitiveness.
Smart Service Prototyping
(2021)
This chapter is dedicated to prototyping, one of the steps of the Smart Service Engineering Cycle. It includes three phases: realizing core functionalities, developing core functionalities, and testing functionalities with customers. In order to realize prototypes successfully, methodical aspects of rapid IoT prototyping are used.
First of all, this chapter explains the motivation behind rapid prototyping and provides an introduction to the approach. The concept of rapid IoT prototyping is based on the idea of developing short-cycle solution variants on the basis of benefit hypotheses or benefit promises and user stories focusing on them. The aim is to achieve data acquisition, aggregation, linkage, processing, and finally visualization by developing it in a vertically integrated manner. Once this is accomplished, the prototype can be evaluated with customers, which also makes it possible to put the benefit hypotheses to the test. Finally, the collected customer feedback can be incorporated more quickly into the development process of new prototype versions, leading to a continuous improvement of the user experience as well as a constant focus on prioritizing the user. Another component of rapid IoT prototyping is working and thinking in terms of minimum viable products (MVP), i.e., solutions that do not meet all of the defined requirements in the first iteration, but are nevertheless already functional.

The digital transformation brings up various new tasks to manage new business application software and integrate them into existing business processes and legacy systems, which are necessary to keep e.g. a production system running. Today, all these tasks are on the one hand not clearly defined and on the other hand, responsibility of these cross-disciplinary tasks is unclear in companies being mostly structured in a function-oriented way. While quality management has developed to a firmly established function of process excellence years ago, IT-application management is still to become an inevitable part of the digital transformation. There are just a few authors trying to define and describe this part, the related tasks, and necessary roles in an organization. In this paper, we show how the business needs of a company can influence the ideal adaptation of the digitization solutions and thus become the success of the digital transformation. We base the paper on a use case in manufacturing companies. We then describe how companies deal with business application systems today. Based on the framework Aachen Digital Architecture Management we describe how a company can holistically improve the management of business application systems.
Low-Level-Code Based Production Model For Improving Material Requirements Planning In ERP Systems
(2021)
Single and small-series production companies face specific challenges, such as variable customer order decoupling points (CODP), decreasing quantities and rising cost pressure. This leads to a increasing production complexity and growing requirements on Production Planning and Control (PPC). Digitalization’s direct links between objects, people, and machines as well as detailed recording of production progresses opens new solutions for PPC. However, volume of data and the required processing times are increasing. Thus, to achieve near-real-time data processing, a decentralization of decision-making systems can be observed. The function Material Requirements Planning (MRP) is PPC’s original need for Enterprise Resource Planning (ERP) systems. Here, PPC’s overall problem (to fulfil primary requirements for products) is divided into subproblems (to fulfil single production orders). Especially companies characterized by an organization in accordance to the workshop principle, high in-house production depth and variable CODP are confronted with high dynamics in their production systems. This ends in significant differences between primary requirements (overall problem) and single production orders (subproblems). Ultimately, these insufficient PPC data result systematically in a non-optimal overall solution despite optimal partial solutions. This publication combines PPC’s fundamentals from existing commonly known models with current implementation concepts of ERP systems. A newly developed Low-Level-Code based Production Model provides explanations for deviations between the overall problem and its subproblems. Furthermore, information flows of PPC can be structured between a periodically actualized vertical and an event driven horizontal information flow. These recognitions lead to an improvement of PPC by ERP systems.
Digitalization and Industry 4.0 continue to shape our industrial environment and collaboration. For many enterprises, a key challenge in moving forward in this matter is the integration of their shop-floor systems (hard- and software) with their office-floor systems to harvest the full potential of industry 4.0.
A multitude of different technologies and respective use-cases available on the market leave many companies startled. This paper presents a set of use-cases for IT-OT-Integration to bring transparency into a company’s digital transformation.
Additionally, a technical requirements profile for integrating IT- and OT-Systems based on the use cases is presented. Both, use-cases and their requirements, guide companies in selecting the digitalization measures that fit their current situation and help in identifying technical challenges that need to be addressed in the transformation process.
Networked digitalisation as an enabler for smart products and data-based business models presents companies with numerous and diverse challenges on their way through the digital transformation. Various reference architecture models have been developed in recent years to support these companies. A detailed analysis of these and in particular their use by companies quickly showed that currently existing reference models have major weaknesses in their practical suitability. With the Aachen Digital Architecture Management (ADAM), a framework was developed that specifically addresses the weaknesses of existing reference architectures and specifically takes up their strengths. As a holistic model, specially developed for use by companies, ADAM structures the digital transformation of companies in the areas of digital infrastructure and business development starting from customer requirements. Systematically, companies are enabled to drive the design of the digital architecture, taking into account design fields. The description of the design fields offers a detailed insight into the essential tasks on the way to a digitally networked company. The model is not only a structuring aid, but also contains a construction kit with the design fields to configure the procedure in the digital transformation. The procedure differentiates between the development of the digitalisation strategy and the implementation of the digital architecture. Three different case studies also show how ADAM is used in industry, what structuring support it can provide and how the digital transformation can be configured. The breadth and depth of ADAM enable companies to take the path of digital transformation systematically and in a structured manner, without ignoring the value-creating components of digitalisation. This qualifies ADAM as a sustainability-oriented framework, as it places the economic scaling, needs-based adaptation and future-oriented robustness of solution modules in the focus of digital transformation.
