Towards a Domain-Specific Language for Product-Process-Resource Constraints

In Cyber-Physical Production System (CPPS) engineering, the basic planner defines CPPS functionality and constraints between Product-Process-Resource (PPR) views to specify valid CPPS process and resource designs. While there are approaches for the visual representation of PPR constraints, such as the Formal Process Description standard (VDI 3682) and its extensions, these representations are hard to process for machines. In this paper, we explore and initially evaluate the design of a Domain-Specific Language (DSL), the PPR DSL, to effectively and efficiently represent and evaluate PPR concepts and essential constraints between them, illustrated in the use case Rocker Switch. We propose a research agenda for the development and in-depth evaluation of the PPR DSL.
