Multi-modeling Approach to Performance Engineering of Cyber-Physical Systems Design

Abstract

The modeling and analysis of Cyber Physical Systems (CPS) is inevitably challenging due to the intrinsic problem of merging the specification of different ensembles that indicate hardware, software and physical aspects of such systems. This intrinsic complexity is exacerbated in performance engineering since multiple models need to co-exist in order to get meaningful performance indicators. In this paper we introduce a guided process called IMPACt (multI Modelling performAnce Cps),which helps architects during the design phase, to better understand the behavior of the system under development and the design choices they made, through performance analysis on results obtained by runnable models derived from system high-level specification
