摘要：
To simplify the integration testing of the complex system of space effective payloads. a method for automatically generating test paths based on system modeling language (SysML) is proposed by introducing the concept of model-based systems engineering (MBSE). The required information is all derived from the SysML digital models constructed during the digital design stage of the payload. Firstly, the SysML activity diagram of the payload is preprocessed. Secondly, the test path search model is constructed based on the characteristics of the payload and the activity diagram, and an improved ant colony algorithm is proposed to search for all the test paths. Finally, based on the SysML use case diagram, a further search is performed among all the test paths to obtain the test paths for the specified functions. The detailed procedure of the proposed method is demonstrated with the example of a space combustion science experiment payload. and the performance of the proposed algorithm is analyzed. In 200 repeated experiments. the coverage rate of the test paths obtained by the proposed method is 100 %, and the maximum number of iterations is 27. The experimental result showes that the proposed method can bring the efficiency of test paths planning to the next level without the generation of a large amount of unefficient test paths. © 2024 Chinese Institute of Electronics.
