Abstract

Labelled weighted transition systems (LWSs) are transition systems labelled with actions and real numbers. The numbers represent the costs of the corresponding actions in terms of resources. Recursive Weighted Logic (RWL) is a multimodal logic that expresses qualitative and quantitative properties of LWSs. It is endowed with simultaneous recursive equations, which specify the weakest properties satisfied by the recursive variables. We demonstrate that RWL is sufficiently expressive to characterize weighted-bisimilarity of LWSs. In addition, we prove that the logic is decidable, i.e., the satisfiability problem for RWL can be algorithmically solved.
