Model´s decomposition and instances transformation in workflow management system

With the definition of workflow management system´s basic component, such as workflow model, process object, process instance, object instance, etc., the main workflow models based-on two-triple were founded, and transforming model based-on triple was set up. The related logical route of restructure and translation were presented. Two ways of coordination were proposed. The theory and the way of coordination oriented workflow model are discussed emphatically. In order to meet with the real need, a workflow instance is given, which is based-on model decomposition and instance transformation.
