Handling Strategy of Dynamic Resource Events in Cyber-Physical Production Systems by a Multi-Criterial and Multi-Operational Approach

摘要

This paper proposes a handling strategy for dynamic resource events in Cyber-Physical Production Systems (CPPS). Because of the increasing complexity and the dynamic run-time behavior, future automation systems become more and more fragile. New methods are needed to deal with such a dynamic behavior, exploiting existing degrees of freedom. Currently, existing methods are limited to single resource operations and/or single-criteria metrics. The contribution of this work is a new approach for the dynamic management of resource events within CPPS. Therefore, a multi-criterial and multi-operational method is introduced. The proposed metric covers functional and non-functional properties and can easily be adapted to an application's needs. The concept is evaluated by an application example from the field of process engineering. Quantitative results are gained by the simulative part of a CPPS-middleware prototype for physical as well as cyber resource events. The results show that the method is able to gain a higher requirement fulfillment under dynamic conditions than unmanaged concepts do.
