For the tasks of different participants and requirements of resources information sharing needs of complex product project in the WBS decomposition process, as well as the problems of design, manufacture and the disconnect between tourism management information transfer, the thesis puts forward the formal method to the metadata by using ontology model and description logic. Through the interaction of formal metadata sharing of heterogeneous data through is realized. Taken large OKP enterprise as the object of study, firstly, the data model in material management are domain analyzed; providing effective carrier for the emerge of static data in the work breakdown process of complex product by constructing ontology, the thesis abstracts related concept class to construct domain ontology model. Then, carrying out the formalized description on material management domain ontology model combined with the description logic. Finally, combining typical complex manufacture of Marine product, carrying out the project modeling and decomposition from three levels, the concept, business domains, activity domain, reveal the relationship between task at all levels, suited to the characteristics of the complex product project WBS model is established. The experiment shows that the constructed ontology model can effectively solve the problem of enterprise heterogeneous data sharing. Model has a certain commonality and can be reused for other subject areas, providing an effective way for unambiguous sharing of the enterprise business information.
