The deployment of modern information and communication technologies (ICT) within manufacturing systems leads to the creation of so-called cyber-physical production systems that consist of intelligent interconnected production facilities. One of the expected features of cyber-physical production systems is found to be the capability of self-organization and decentralized process planning in manufacturing. The functionality as well as the benefit of such self-organization concepts is yet to be proved. In this paper, the implementation of a virtual test field for the simulation of manufacturing systems based on a multi-agent system modeling concept is presented and used to evaluate a concept of decentralized process planning. Thereby, special focus is laid on the impact on energy consumption. The simulation results show the potential for energy reduction in manufacturing by a decentralized process-planning concept and yields hints for further development of such concepts.
Modern cyber-physical production systems (CPPS) connect different elements like machine tools and workpieces. The constituent elements are often equipped with high-performance sensors as well as information and communication technology, enabling them to interact with each other. This leads to an increasing amount and complexity of data that requires better analysis tools to support system refinement and revision performed by an expert. This paper presents a user-guided visual analysis approach that can answer relevant questions concerning the behavior of cyber-physical systems. The approach generates visualizations of aggregated views that capture an entire production system as well as specific characteristics of individual data features. To show the applicability of the presented methodologies, an exemplary production system is simulated and analyzed.
Clean air policy faces not only the classical problems like multi-pollutant aspects but also complex consequences of instruments on production costs, competition and consumption. A new model can support clean air policy in Germany.
Studying the goals, ideas and trends of the concept of cybertronic production systems (CTPS) leads to the hypothesis that CTPS supports a sustainable development. The paper proposes an approach for simulating and verifying this hypothesis.
Cybertronic production systems are formed by the application of cybertronic systems (CTS) in production. To examine the behavior of cybertronic systems depending on their level of interconnection, intelligence and independence a multi-agent system of a production system is implemented. This simulation system can be used as virtual test field to evaluate impacts of changes in the production system on all level of detail (process, machine tool, factory level) by using sustainability indicators on factory level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
