Formal specification and analysis of a control system based on computer networks

Abstract

The control architecture for a distributed application (elevator system) is at first specified in terms of functionalities, networks and exchanges on networks. This architecture is based on two types of local area network (CANs and one network with a centralized control). Second, this architecture is modelled with stochastic timed Petri nets which allow one to express the main mechanisms of real time distributed systems and to do qualitative and quantitative analyses. Properties and performances of the elevator system are verified and evaluated.
