The Petri Net model of the requirements and service composition
In the service-oriented environment,the composition of multiple web services is always used to satisfy the given request.To meet the request,the compositions of the services are various.Aim at such difficulty,described with the environment ontology,the relative theory of Petri net is proposed to build up the service composition requirement model After simplify the model,an algorithm of building a reachability tree is proposed.Then all the possible service compositions are got through an algorithm similar as depth-first search.At last,we use the classic example of travel arrangement to verify the theory above all.
