Service-Based Software Systems

The goal of this chapter is to show the characteristics of service-based software systems as systems of systems, and how their simulation counterparts can be developed using a DEVS modeling approach. We show how standards such as Service-Oriented Architecture (SOA) play key roles in developing simulation models that are better equipped to be interchanged with their real counterparts. Generic SOA-compliant DEVS model components are developed to closely represent their real counterparts and are used to develop simulation instances of real service-based software systems. Users can systematically and efficiently prototype service-based software systems in simulated settings with capability to evaluate their quality of service attributes such as timeliness and accuracy.
