SOCIETY & ”INDUSTRY 4.0”
Web services are application components that can be linked together for creating new functionality. As such, they support industry environments by binding together inhabitant services with distributed on demand services for implementing the business strategies. However, web services are operating in dynamic environments and an important issue during the composition process is change management either at the local or at the web, in general. Therefore, service changes together with other nondeterministic behaviours must be efficiently propagated to ensure the validity and consistency of the enterprise plans. Simulations are effective tools for enhancing factory competitiveness. Simulating the operation of a developed composite service for verifying the developed product could be a solution to this problem. The results of the simulation will allow to predict and react to such behaviours before applying the developed service in real production. As such, this paper describes and compares the existing service simulators that could be used in smart industry environments in terms of their functionality. Based on this review, the identification of gaps in performing simulation of service composition in industrial environments is presented, and challenges to be met on the field are outlined.
