Synthesis of Orchestrations and Choreographies: Bridging the Gap between Supervisory Control and Coordination of Services

Authors: Basile, Davide and ter Beek, Maurice H. and Pugliese, Rosario

We present a number of contributions to bridging the gap between supervisory control theory and coordination of services in order to explore the frontiers between coordination and control systems. Firstly, we modify the classical synthesis algorithm from supervisory control theory for obtaining the so-called most permissive controller in order 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. Then, we present an abstract parametric synthesis algorithm and show that it generalises the classical synthesis as well as the orchestration and choreography syntheses. Finally, through the novel abstract synthesis, we show that the concrete syntheses are in a refinement order. A running example from the service domain illustrates our contributions.
