Research on credibility of web service composition based on Stochastic Petri net

Abstract

The service-oriented architecture (SOA) has become inevitable in the development and wide application of computers and networks. SOA is characteristic of service composition so that it can provide more services to companies. While there is a promising future for the application of web service composition, some issues such as safety and reliability hinder its further development. To increase the trustworthiness of web service composition, the paper puts forth some indexes and a Petri net based approach. The credibility of web service composition can be evaluated with this approach. © Springer-Verlag Berlin Heidelberg 2013.
