    As a result of the growing demand for highly customized and individual products, companies need to enable flexible and intelligent manufacturing. Cyber-physical production systems (CPPS) will act autonomously in the future in an interlinked production and enable such flexibility. However, German mid-sized plant manufacturers rarely use virtual technologies for design and validation in order to design CPPS. The research project Virtual Commissioning with Smart Hybrid Prototyping (VIB-SHP) investigated the usage of virtual technologies for manufacturing systems and CPPS design. Aspects of asynchronous communicating, intelligent- and autonomous-acting production equipment in an immersive validation environment, have been investigated. To enable manufacturing system designers to validate CPPS, a software framework for virtual prototyping has been developed. A mechatronic construction kit for production system design integrates discipline-specific models and manages them in a product lifecycle management (PLM) solution. With this construction kit manufacturing designers are able to apply virtual technologies and the validation of communication processes with the help of behavior models. The presented approach resolves the sequential design process for the development of mechanical, electrical, and software elements and ensures the consistency of these models. With the help of a bill of material (BOM)- and signal-based alignment of the discipline-specific models in an integrated mechatronic product model, the communication of the design status and changes are improved. The re-use of already-specified and -designed modules enable quick behavior modeling, code evaluation, as well as interaction with the virtualized assembly system in an immersive environment.

    Interlinked and autonomous manufacturing systems provide new opportunities in smart manufacturing. Today's manufacturing system design processes and architecture still are based on traditional engineering methods and can hardly cope with increased system complexity. Hence new cyber physical production systems (CPPS) design and architecture principles as well as corresponding validation and verification methods are necessary. This paper presents firstly a new architecture design approach for modularised design of CPPS. Secondly, new capabilities in designing with modular construction kits, simulating functional behaviour and validating with virtual, functional prototype are introduced. Thirdly, a proposal for the development approach and virtual validation is presented and risks as well as challenges are discussed.
