Evaluation of selected metrics for flexibility of Cyber Physical Production Systems

Flexibility of Cyber Physical Production Systems (CPPS) has already been widely discussed, but apart from some definitions, only few measures exist. These, however, are required to compare different CPPS regarding their flexibility and the effort necessary to increase flexibility during evolution. This paper presents the application and evaluation of already proposed flexibility and adaptivity metrics for automated Production Systems. The interdependencies among product, process and resource are shown. An AML description is provided for a lab size application example as a basis to demonstrate changes that incorporate flexibility. Such changes are to produce heavier work pieces (WPs), realize different processes and use different resources. At the example of the model in Automation ML, we highlight the interdependencies between product, process and resource, thus showing the strengths and weaknesses of the proposed metric.     «
