Formal Verification of Evolutionary Changes

Abstract

In this chapter, we elaborate how formal verification techniques can be used to ensure safety properties of automated production systems during their evolution. First, we discuss the opportunities that formal methods offer, particularly when dealing with the evolution of automated production systems, but also which special needs this particular domain requires from the formal methods to be applied. We exemplarily present three approaches that successfully incorporate a formal verification technique for analysis, modelling, or reasoning into the system evolution process, namely, regression verification, generalised test tables, and model checking of holistic (multidomain) models.
