A Web Service is a component written in any language, deployed on any platform, which has a standardwrapping layer based on XML.The component can interact with other applications which themselvescomply with the Web Services standards.Generally, a singleservice does not satisfy the users needs thatare more and more complex.Therefore, services must bemade abletobecomposedto build new valueadded services. This process is called Web services Composition. Thislatter is a critical subject thatrequires formal techniques for its completion. In this paper, we show how basic and existent services canbe composed to create a composite service which offers a new functionality. In this context, we propose anexpressive Labeled generalized stochastic Petri net based algebra that succeeds in the complex Webservices composition. Basic and advanced constructs which are supported by the proposed algebra aresyntactically and semantically defined
