Test sequence generation and optimization method based on Cooperative Vehicle Infrastructure System simulation

The Cooperative Vehicle Infrastructure System (CVIS) is a complex real-time system. This paper will discuss about the test sequence generation and optimization during Cooperative Vehicle Infrastructure System simulation. The demands and characteristics of this system will be analyzed, and then the function of the system characteristics and test conditions could be constituted by using fault tree algorithm. By dealing with these functions, timed automata model have been researched for the suitable of the CVIS simulation. According to the model, the system test is modeling and verification by using UPPAAL. The problem of automatic sequence generation in this paper has been solved in CVIS test to some extent. This paper also discuss the firefly algorithm with optimizing the test sequence that generated by timed automata model. And it shows that firefly algorithm is efficient in optimizing.
