SimuLizar NG: An extensible event-oriented simulation engine for self-adaptive software architectures

Abstract

Software simulation constitutes an essential mechanism for design time architecture analysis. Domain-specific software, e.g. of cyber-physical systems, requires domain-specific extensions to the architecture models and their execution semantics. Existing simulators are cumbersome to extend, do not support self-adaptivity or do not scale well. In this paper we present concepts of SimuLizar NG, a scalable simulation engine for the SimuLizar approach. Its principal goal is to facilitate domain-specific extension and adaptations to the model interpretation semantic while at the same time ensuring reactive simulation execution in demanding scalability scenarios.
