Bridging the gap between supervisory control and coordination of services: Synthesis of orchestrations and choreographies

Abstract

We explore the frontiers between coordination and control systems by discussing a number of contributions to bridging the gap between supervisory control theory and coordination of services. In particular, we illustrate how the classical synthesis algorithm from supervisory control theory to obtain the so-called most permissive controller can be modified to synthesise orchestrations and choreographies of service contracts formalised as contract automata. The key ingredient to make this possible is a novel notion of controllability. Finally, we present an abstract parametric synthesis algorithm and show that it generalises the classical synthesis as well as the orchestration and choreography syntheses.
