As the foundation of simulation modeling credibility evaluation , VV&A exists throughout a project's whole life cycle .The thesis thoroughly analyzes VV&A simulation modeling credibility validation methods , especially the widely applied grey relational analysis .Aiming at the problems exist in grey relational analysis , the thesis puts forward an improved method , which is compared against existing methods .In-stance test is carried out to show that the improved algorithm is more obvious about the simulation modeling credibility validate effect .For ca-ses like either geometry similarities or corresponding point overly distant situation it nevertheless does a good job .It is of guidance signification for simulation modeling credibility verification in engineering applications .%VV＆A（ Verification， Validation and Accreditation ）作为仿真建模可信度评估的基础，贯穿于项目的整个生命周期。对VV＆A仿真模型可信度验证方法及其中广泛使用的灰色关联分析法进行了深入分析，针对灰色关联分析法中存在的问题提出一种改进方法，并与已有算法进行比较分析。经过实例测试，改进后的算法对仿真模型可信度的验证效果更加明显，对于几何形状相似、对应点平移距离极大的情况做到了兼顾，对工程应用中仿真模型可信度验证具有指导意义。
