Abstract—As a way to compose independent service together to fulfill a function, service composition is an important means for flexible and rapid information integration of complex distribution application in open and heterogeneous environment. However, the diversity of requirements makes it difficult to guarantee the correctness of service composition. This paper proposes a hierarchical dynamic service composition net (HDSC-net), and user's preference based mechanism for service composition. HDSC-net is used to model operation, the relationships between operations, operation mapping, and user's preference. Transfer matrix is constructed to express the relationships between states, while theories of Petri nets help prove the composability of service. The strategy for dynamic service composition and its corresponding enforcement method are also proposed. A case study of Travel Service demonstrates the applicability of proposed method and its effectiveness.

Index Terms—Web service, service composition, user's preference, transfer matrix, composability.
