The principles and process of manufacturing service composition are proposed.

Semantic-based virtual enterprise manufacturing services modeling technology;

To improve recall ratio & precision ratio of manufacturing services in service oriented architecture environment,a manufacturing service chain construction method based on product structure was proposed.

In order to construct collaborative manufacturing service chain, a method for modeling and compositing manufacturing services is presented based on service oriented architecture.

Aimed at some malpractices in the production course of punching die of railway vehicle factory,a study was carried out on manufacturing service system that supports the development of cooperative product based on Web.

In order to resolve the service description problem of service composition, a service description method including mainly a (input-output) interface model and a data flow diagram model is put forward.

In order to resolve the automatic service composition,pervasive service is presented as Colored Petri Net,which can describe the functional semantic of service.

This paper makes research on the conception and feature of the Web services composition, and elaborates on the analysis of the dynamic service composition mechanism of WS-Addressing and BPEL with a specific example.
