An Activity-centric Software Process Modeling Tools, The Design And Realization

At the beginning of this paper, we introduce the research background and some hotspots in software process engineering field. Using the PSEE(Process-Centered Software Engineering Environments) technology, we provide a visual PML(Process Modeling Language) based on UML activity graphic, and discuss the software process model's rationality problems which are checked with a set of rules defined by us.To define the visual PML, We give a Meta model of process-centered software PML. After combining the Meta model with the UML activity graphic, we bring forward our visual PML and its formalization, then provide the mechanisms to transfer our visual PML into XML format and vice versa.To check the rationality problems of the software process models constructed with the Meta model and visual PML, we analyze fifteen process model's rationality problems which were divided into three kinds, and present corresponding rules to solve them.With the above work, we design and develop a software process modeling tool with Java/J2EE and XML technologies, to implement our researches on the visual PML and model's rationality check.Finally, based on Dowson's framework, J2EE technology and our visual PML, we design a PSEE which includes three parts: a software process modeling tool, a software process engineer and the workspace of the PSEE, and the first part has been implemented.
