Abstract

This paper considers the rigorous design of Systems of Systems (SoS), i.e. systems composed of a set of heterogeneous components whose number evolves with time. Such components cooperate to accomplish functions that they could not achieve in isolation. Examples of SoS include smart cities or airpo

Summary

Introduction

Context and challenges A System of Systems (SoS) is a large-scale, geographically distributed set of. One of the main contributions of the paper is a full integrated tool-chain between IBM Rhapsody, the statistical model checker PLASMA [5] and DESYRE This tool-chain is, to the best of our knowledge, the first one offering a full SMC-based approach for the verification of complex heterogeneous systems. We propose to support wide-spread industry standards for SoS This is done by exploiting UPDM [11] for SoS architecture design and the FMI standard for constituent systems integration. This tool-chain is demonstrated on an industrial case study, where we show its application to a Fire Emergency Response system designed in DANSE [12], modeling a complex SoS that manages fire emergencies in a large city This tool-chain is demonstrated on an industrial case study in Section 7, where we show its application to a Fire Emergency Response system designed in DANSE [12], modeling a complex SoS that manages fire emergencies in a large city
