Cyber-Physical Production System Design Decomposition for Internal Disruption Avoidance

A growing number of manufacturing companies are undergoing digital transformation and moving towards Cyber-Physical Production Systems (CPPS). To ensure the long-term resilience of CPPS by avoiding internal disruptions, the starting point is the proper design of a functional digital shadow. Therefore, the goal was to provide decomposed design guidelines for the digital shadow implementation. The Axiomatic Design (AD) method was applied to discard systems-based categorization and decompose design parameters from functional requirements, which guided a novel approach covering digital shadow design guidelines. Through the zigzagging process, we elaborated collectively exhaustive and mutually exclusive conceptual design parameters. The received results were applied to a cyber-physical demonstrator. The practical value of the received design parameters guided towards alternative digital solutions, and based on AD axioms, the selection of digital solutions was implemented on the demonstrator. Such an approach enabled us to cover the full concerned functionality while avoiding decoupling and overlapping in implemented solutions.
