Observability Analysis of Discrete Event Systems Modeled by Concurrent Synchronous Products
Longjiang Wang, Shigemasa Takai (Osaka Univ.) MSS2012-52
Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we study supervisory control of concurrent discrete event systems under the assumption that both the plant and the specification are modeled by concurrent synchronous products. Controllability and observability are necessary and sufficient conditions for the existence of a supervisor under partial event observation. We first show that if the specifications of all subsystems are controllable and observable, then the specification of the entire system is observable. Further, we present sufficient conditions under which observability of the specification of the entire system implies that of the specifications of all subsystems.
