Planning and developing Cyber-Physical Production Systems (CPPS)
are multi-disciplinary engineering activities that rely on effective and efcient knowledge exchange for better collaboration
between engineers of different disciplines. The Product-ProcessResource (PPR) approach allows modeling products produced by
industrial processes using specifc production resources. In practice, a CPPS manufactures a portfolio of product type variants, i.e.,
a product line. Therefore, engineers need to create and maintain
several PPR models to cover PPR variants and their evolving versions. In this paper, we detail a representative use case, identify
challenges for using Variability Modeling (VM) methods to describe
and manage PPR variants, and present a frst solution approach
based on cooperation with domain experts at an industry partner,
a system integrator of automation for high-performance CPPS. We
conclude that integrating basic variability concepts into PPR models is a promising frst step and describe our further research plans
to support PPR VM in CPPS.
