摘　　要：针对复杂制导仿真系统可信度量化的主观性和不确定性,给出了基于证据理论和灰云聚类的仿真可信度评估模型。首先以群组层次分析法获得多位专家的意见,并对不一致意见进行证据理论融合,得到具有更高可信度的指标权重;然后采用灰云聚类的方法,以灰云模型作为白化权函数,对定性评价进行量化处理,最后通过计算灰色聚类系数完成对仿真系统的可信度评估。应用此模型对制导半实物仿真系统进行评价,结果符合客观实际,表明该模型具备可行性和实用性,为仿真可信度评估和综合评价问题提供了一种新的有效途径。Given the subjectivity and uncertainty of the credibility quantification of complex guidance simulation system,an evaluation model of simulation credibility based on D-S evidential theory and gray cloud cluster is proposed.Firstly,the experts′opinions are obtained by AHP,and different opinions are combined by D-S to obtain the index weight of higher credibility.Then the gray cloud-clustering model is adopted to quantitatively processing the qualitative results as the whitening weight function in grey clustering.The credibility of the simulation system is evaluated by calculating the gray clustering coefficient.Finally,the evaluation of the HILS simulation system is carried out and the results show that the model is feasible and practical.This model provides a new and effective way for the simulation credibility evaluation and comprehensive evaluation.
