A Logical Petri Net-Based Approach for Web Service Cluster Composition
Wu Hong · Chinese Journal of Computers · 2015
Web service composition is an important way to achieve value-added services and software reuse,but the existing static service composition and dynamic service composition methods are all needed to be further improved.This paper integrates the advantages of static composition and dynamic composition methods and proposes a method that composes service clusters in a virtual layer to realize service composition.A service composition approach based on service clusters is developed and logical Petri nets are used for its formal modeling.Basic composition models of service cluster nets(SCNs)are presented and the inheritance conditions of their completeness are analyzed respectively.The algebraic properties of SCN composition are also presented.Finally,experimental results are presented to illustrate the applicability and effectiveness of SCN composition.
