Statistical model checking of distributed real-time actor systems

Abstract

This paper proposes an approach to modelling and analysis of distributed real-time actor systems, which is based on the Uppaal statistical model checker (SMC). SMC was chosen because it automatizes simulations, offers a temporal logic language to formalize specifications and exploits statistical techniques to infer quantitative measures about a model. The approach is integrated in a system life-cycle where a same model can be transitioned without distortions from analysis down to design and implementation, currently based on Java. The paper describes the adopted actor modelling language and its architectural framework, illustrates the Uppaal SMC approach and demonstrates its practical usefulness through a running example.
