The Spacecraft Automatic Testing System Based on Workflow

Spacecraft automatic testing has been a focused theme in spacecraft technology researches for over a decade. However, there is less attention on the spacecraft automatic testing technology based on workflow methodology. In this paper we introduce workflow technology into spacecraft testing field in order to improve the automation level of spacecraft testing. Firstly we present the architecture of spacecraft testing system based on workflow. Then a spacecraft testing process definition language STPDL is proposed based on XPDL, which is used to model testing processes. In addition, we give the detail execution processes and core scheduling algorithm in the spacecraft testing execution system. At the end of the paper we investigate the efficiency of the testing execution system.
