A Workflow Model based on Homogeneous Activities

In process-oriented software systems, many processes have large number of parallel redundant activities which are often used in split and merge workflow structures and make workflow model too complex to manage. Aiming at the homogeneity of redundant activities the structure characteristics of these homogeneous activities are analyzed and they are being classified into eight modes. Also the constraints is identified which defined the coexistence of these modes. At last a workflow model based on homogeneous activities is presented. Comparison shows that the method has obvious advantage in reducing description time and maintaining cost of workflow model.
