Research And Application On Autonomic Building Methods Of Web Service For Rapid Prototyping

In recent years, with the rapid development of rapid prototyping (RP) and web services, information technology and the integration of the cross for RP field, network integration services development of RP domain has become a research hotspot. Constructing RP Web service alliance and improving the enterprise's quickly response ability is the inexorable trend of manufacturing industry. How to make the heterogeneous distributed resources information system to achieve better information access and query, realizes the interoperability between systems, finding needed services rapidly and efficiently, solving the system complexity, will be a challenge when realize resource intellegent sharing and servicing, but also a problem which to improve the service informatization level for RP industries to be solved. This dissertation discusses the autonomic building methods of web service in the field from constructing RP enterprise networked integration services platform, which reaches RP resources sharing and technical advantage complementary by practical application and testing.This dissertation focuses on problems as follows:It summarizes the development characteristics of RP industries, analyses the informationization requirements, layered structure of RP service system platform is designed and the composition is described. The design method and establishment principle of RP domain ontology oriented are proposed on the basis of ontology concept, the RP domain ontology model is constructed. It is conveniently to search and realize resources integration so that information query and knowledge sharing efficiency are raised.The system structure of service registtation center and service describe model are built by using OWL-S service registration, web service discovery layered matching algorithm and the method that automatic service composition converts workflow are proposed, it can solve the semantic support problem of system structure. To achieve the formal description of web service compositon, it is verified by time Petri net through workflow modeling. It analyses the service compositon in the field of RP business process and the model rationality is verified, which can reduce the response time of system and improve service efficiency by the implementation of process optimization. Combined with the theory of autonomic computing sytem and autonomic building method of service, a self-management framework is proposed for RP manufacturing process service. According to process service characteristics, the dissertation analyses the self management from the self-configuration, self- optimization and self-protection in view of the practical cases. It provides an effective technology theoretical support that improves the autonomy of system management.Based on the study of theories and methods, we develop a prototype system of networked service for RP field. The system which takes engineering application of rapid manufacturing engineering center as object, achieves the functions such as description of domain ontology and autonomic management of system. The process service has been tested and verified by practical cases in many enterprises, and has made good effect.
