Formal Verification of Safety Analysis Models of Repairable and Reconfigurable Systems

Abstract

This paper proposes a method to formally check whether formal properties hold on a dynamic model which has been designed by experts for Model Based Safety Analysis/Assessment. As repairable and reconfigurable systems are considered, this model is assumed to be described in the Generalized Boolean-logic Driven Markov Processes (GBDMP) modelling framework. Translation rules are given to obtain a formal model that describes correctly the evolution of the initial model with the semantics of the verification tool. The approach is exemplified on a simple case of standby redundancy.

A safety simulation analysis algorithm for Altarica language

“…Jiao and Zhao 12 analyzed and abstracted the entities in the social technology system and their behavior in the accident scene, trying to add new entity elements to the model to create entity‐oriented ESD (EOESD). Kobeissi et al 13 proposed a method for formal checking of the presence of formal attributes on a dynamic model designed by a model‐based safety analysis/evaluation expert.…”
