Coordination-Policy Based Composed System Behavior Derivation

Abstract

The coordination-policy that components interactions satisfied often determines the properties of nowadays component-based information systems, e.g. safety, liveness and fairness etc. Therefore, how to derive coordination-policy satisfying behavior all out of such system to achieve better system properties is of a significant problem that needs to be solved. Aim to this problem, we propose an optimistic policy- satisfying behavior derivation approach in this paper. The main idea of the approach is to automatically construct a Coordination Environment (CE) for such composed system that system components can work together in a deadlock-free and policy-satisfying manner, and so as to obtain desired system properties. In this approach, component-based information system is modeled by interface automaton network (IAN), and component coordination-policies are specified by LTL. To explain the correctness and validity of this approach, we give a corresponding example certification.
