The Distributed Workflow Engine Model Design of the Space Test and Launch

Workflow technologies are becoming pervasive in the area of space. They enable the execution of space business processes in distributed and ubiquitous computing environments. However, there are some problems such as cross-platform workflow which need to be solved urgently in space test and launch. Aiming at enhancing the efficiency of space test and launch, the distributed workflow engine model of the space test and launch based on JMX was designed. And the workflow engine routing control algorithm was proposed. At last, the performance of the workflow engine system was analyzed. The model was applied in a launch base successfully. The actual operation tests show that: the proposed design model was rational and effective. It enabled changing the engine process dynamically and enhancing the flexibility of the engine system. Furthermore, it enabled setting workflow engines according to the task and application of the test and launch departments. The performance and efficiency of the space test and launch system was improved greatly.
