Meta Web Service based Distributed Model Management and Composition Approach

To satisfy the requirement of making scientific decision quickly and correctly in distributed network environment, a Meta Web Service based Distributed Model Management and Composition Approach is proposed. The Overall framework of Meta web service is designed, and each component is analyzed. An improved model service matching algorithm is given. Utilizing backward reasoning technique to compose model services dynamically and automatically, a process is then given which uses several model services to compose to make a single service. Compared with traditional model management approach, the approach provided here has the functions of model remote calling and running, automatic composing and executing etc., which provide a new approach to build model system for decision support system solving complex problems.
