A Goal Driven Configurable Service Workflow Model

Service computing is being a prevailing software paradigm now and also becomes the underling supporting technology for grid environment. Since single service can only provide limited functions, they are often be combined by a service workflow model so that users requirements can be meet by executing some service workflow model. In order to support various users requests through a common workflow, the service workflow model should be configurable, i.e., they can be refined into different forms. A rule driven service workflow model is presented in the paper. And a goal driven service workflow customization method is introduced. A prototype system is also presented.
