In order to solve the problem of conversions among workflow management system models, and improve the efficiency of the development of workflow management systems. Based on model driven architecture(MDA), the paper gives the workflow model, and utilizes transformation languages to generate source model. In the actual process of software development, the method is conducive to improve the efficiency of development. In this paper, the method can adapt to the diversities of external environment, and improve the workflow management system robustness which has a certain application significance.
