Fundamentals of artifact reuse in CPPS

Abstract

Recent research and development activities within the field of production system engineering and use focus on the increase of production system flexibility and adaptability. One common issue of those approaches is the consideration of hierarchical and modular production system architectures where the individual components of the system are equipped with certain functionalities and information. Up to now there is no common understanding about what a component can constitute, i.e. which parts of a production system can be regarded as components within the hierarchy and which functionalities and information are assigned to it. This gap will be closed within this and the subsequent two chapters. They will at first discuss the relevant layers of components in a production system, then the types of information required to be assigned to a component on the different layers to establish a digital representation of the component, and at last the description means exploitable to represent the identified information in the different life cycle phases of a production system. This chapter in particular will consider hierarchies of production system components and their life cycle. Based on a literature survey and practical experiences candidates for hierarchy layers and their identification criteria are named. In addition, main life cycle phases of production systems are discussed.
