Integrated Avionics System Simulation Credibility

The simulation technology is an important branch of model science and technology. Because of the advantage in such respects as its security , dependability , effectiveness , economy and controllability repeatability ,etc, this technology have already applied to the course of grinding , developing , testing etc. The simulation technology has important function to the defense industry particularly. We can save the expenses on the products greatly in the course researching;can shorten the cycle of developing. With the development of the simulation technology, People pay attention to the credibility of system simulation more and more .In other word could the simulation system reflect the performance of artificial system? And could the result be accepted by user?This text is based on the Integrated Avionics System, and we apply the analytic hierarchy process to study the credibility of system simulation;we also apply the simulation theory to research the credibility of system simulation on the basis of outside hang weapon. Finally, because the artificial credibility is a fuzzy concept , so we can not have a clear concept of the usability with a certain credibility, so we have put forward and introduced the fuzzy judgment method to judge of the credibility of system simulation and the course of its application.
