Research And Design On Visible Workflow Modeling Implement

Workflow management technology is the core technology for achieving corporation process reformation, process management and process automatization. Workflow modeling express practical management process in the form of computer language. It is the base of workflow management technology. Workflow production has a steady post after beginning and development of 1980s and 1990s.Although workflow technology has achieved distinct success it has many shortage such as standardization.The design pricinple of this workflow modeling implement is standization, usable, and correct. Workflow modeling based on the activity network is straight and wieldy. Petri network modeling has rigorous mathematics logic, firstly, this paper compares the two modeling method, secondly, this paper completes a modeling implement. It's express mode is activity network and it's calculator model is Petri network. The output file is a xml file which fulfill xpdl criterion. In addition, this paper discusses some kinds of workflow pattern and their express methods. Workflow model includes process model, organization model and resource model. Their relation is that process model complete modeling by citing organize model and resource model. This paper discusses organization which storaging model in the form of tree, use model by the dynamic workgroup, so the relation between organization model and process model is released. Resource model is as so as Organization model.To verify syntax and structural correctness, we can rely on mathematical methods. Syntax correctness is easy to verify, but structural correctness is difficult to verify. A structural conflict verification method of workflow mode based on graph reduction is introduced in this paper.
