The paper presents the evaluation of the dependability performances of a real On-Board Communication System of a Metro train centered on the application of RAMSAS, a recently but promising model-based method for the reliability analysis of systems through Simulation. In particular, after the description of the On-Board Communication System under consideration, of its dependability requirements, and related performance indicators to be evaluated, a SysML-based model of the structure and behavior of the system is presented. Beside the nominal system behavior, specific dysfunctional tasks, able to alter the intended behavior of the system, are introduced in order not only to evaluate through Simulation system dependability performances but also to compare different design choices and parameters settings against the requirements.

Abstract

The paper presents the evaluation of the dependability performances of a real On-Board Communication System of a Metro train centered on the application of RAMSAS, a recently but promising model-based method for the reliability analysis of systems through Simulation. In particular, after the description of the On-Board Communication System under consideration, of its dependability requirements, and related performance indicators to be evaluated, a SysML-based model of the structure and behavior of the system is presented. Beside the nominal system behavior, specific dysfunctional tasks, able to alter the intended behavior of the system, are introduced in order not only to evaluate through Simulation system dependability performances but also to compare different design choices and parameters settings against the requirements.
