Abstract: The execution reliability of business process is an indispensable problem in workflow management research. However, there exists the need to solve the death problem of mobile agent in the concurrently coordinating process. Based on migrating workflow model, a reliable execution model of migrating instance is proposed. The model can achieve different levels of implementation of the main monitoring and failure diagnosis and treatment of the monitoring of the design. In addition, the model itself is removable, can be replicated and automatically quit, thus the accuracy of the inspection and efficiency of monitoring can be ensured. Experimental results indicate that the model possesses reliability and low cost and scalability, especially is suitable for the concurrent execution situation in the inter-organizational environments.
