In this paper, we present a model of composition for semantic web services based on statechart. The environment is based on a distributed architecture and on semantic and uniform based-ontology and community service descriptions. Thus, the community constitutes a unified, a homogeneous and a consistent access interface for existing heterogeneous e-services. Moreover, based on the OWL-S language, a rich expressivity both in services and user constraints descriptions is provided. In our work, the composition is realized in two steps: the composition of semantic descriptions and then the composition of the underlying e-services instances executions. In this paper, we present the semantic composition which is based on statechart models deduced from OWL-S service descriptions concerning by user request. The purpose is to define the statechart model corresponding to the user request. This model provides a set of strategies of composition execution by taking into account the nondeterministic behaviors of e-services instances and the user constraints.
