Concurrent service systems are modeled using the Generalized Stochastic Petri Nets (GSPN) to account for the multiple asynchronous activities within the system. The simulated operation of the GSPN modeled system is then optimized using the Particle Swarm Optimization (PSO) meta-heuristic algorithm. The objective function consists of the service costs and the waiting costs. Service cost is the c...

Interorganizational cooperation is more and more organized by the paradigm of services. Service-oriented architectures (SOA) provide a general framework for service interaction. SOA describe three roles of services, the service provider, the service requester, and the service broker, together with the three operations publish, find, and bind. We provide a formal method based on nondeterministic...

Proactive adaptation of service composition has been recognized as a major research challenge for service-based systems. In this paper we describe an approach for proactive adaptation of service composition due to changes in service operation response time, or unavailability of operations, services, and providers. The approach is based on exponentially weighted moving average (EWMA) for modelli...
