Abstract: The evaluation of simulation model credibility has always been a hot issue in the simulation field. How to evaluate the credibility of the simulation is the key to the development of the simulation technology. It is of great significance for our country to carry out the credibility evaluation research. In view of the issue, the grey correlation analysis theory and the related principles in rough set theory are analyzed and the simulation credibility evaluation model based on rough set and grey correlation analysis is proposed. The indiscernibility principle in rough set is used to assign the weight distribution of each factor objectively. The comprehensive evaluation of simulation credibility is carried out by combining the grey correlation analysis method with the indiscernibility principle in rough set. The feasibility of this method is verified through an example of the flight simulation system.

Key words: rough set, grey relational analysis, simulation, evaluation of credibility
