In this paper, after in-depth analysis and research of workflow technology, for the problem that model established and lack of flexibility in the implementation phase and abnormal monitoring of track processing is not timely, designed and achieved a dynamic workflow based on Mobile Agent, the system based on dynamic workflow model and dynamic exception handling model, used the way of“Dynamic Activity”and“dynamically modify the set of operation rules”, to encapsulation for dynamic factors of uncertainty and business processes of implementation phase and correspond to the dynamic operation. The paper established a exception handling mechanism to monitor trace, increased the method of triggering and backward recovery, created an exception rule base in the form of active rule, realized tracking and processing of dynamic monitoring for unusual problem. Combining with the features of Mobile Agent which are mobile, autonomous, interactive, active, intelligent, thesis reduced the load on the single workflow server and the system costs of communication, and created a dynamic workflow management system.
