计算机建模仿真已经发展为重要的产品开发和系统测试手段。仿真可信度对于仿真结果非常重要，但评估仿真可信度的过程常常较为繁琐。因此，需要一个能够便捷正确地评价仿真可信度的评估方法，来完成体系建立、定性定量评估、专家意见汇总等工作。本文介绍了DS 证据理论的原理及其应用，并对传统DS 证据理论在评价系统中应用的局限性进行了改进，同时引入了凸证据作为辅助，建立了基于DS证据理论的复杂产品仿真可信度评估方法。文章最后结合一个算例具体说明了该理论在仿真可信度评估中的应用。

Computer modeling simulation has been developed as an important means of product development and system testing. Simulation credibility is critical to simulation results, but the procedure of credibility evaluation is usually very cumbersome. Therefore, there is a need for a proper method of simulation credibility evaluation, which can finish the work of system establishment, quantitative evaluation, qualitative evaluation and expert advice collection. This paper introduces the principle and application of DS evidence theory, and improves it for the implementation in evaluation system. With the auxiliary of convex evidence, a methodology of simulation credibility evaluation for complex product based on DS evidence theory is established. Finally, an example is showed to illustrate the concrete application of this method in the evaluation of simulation credibility.
