On the semantics of temporal specifications of component-behavior for dynamic architectures

Abstract

In component-based design, temporal logic is a means to specify the temporal behavior of components. If these components are deployed to a dynamic architecture, they can be activated and deactivated over time. Thus, the traditional semantics of temporal specifications of component-behavior does no longer reflect the actual behavior of the components within such dynamic architectures. To address this problem, we provide an alternative semantics of temporal specifications of component-behavior for dynamic architectures, taking into account component activation and deactivation. We show soundness and relative completeness of our semantics w.r.t. the traditional one. The new semantics can then be used to support in the formal specification of dynamic architectures by separating the specification of component-behavior from other aspects such as component activation and architecture reconfiguration.
