摘　　要：针对飞机保障性评估问题,提出了一种基于Vague复合物元-结构熵权TOPSIS法的评估模型.首先,根据保障性定义,构建了飞机保障性评估指标体系,采用结构熵权法,在消除认识盲区的基础上确定指标权重;然后,将Vague集表示法与物元法相结合,构建Vague复合物元;最后,利用加权Vague复合物元相似度与灰色关联度相结合的方法计算各方案与正负理想方案的综合贴近度,对方案进行排序.通过实例分析得到了客观合理的结果,验证了该方法在飞机保障性评估中的有效性,对提高飞机保障性评估的科学性和准确性有一定的实用价值.Aiming at the problem of supportability evaluation of airplane,the authors propose an evaluation model based on Vague compound matter-element and structural entropy-weighting TOPSIS method.Firstly,in accordance to the definition of supportability,the authors build a supportability evaluation index system of airplane and determine the weight by applying structural entropy-weighting method to eliminate blind spot on understanding the weight.Secondly,Vague compound matter-element model is established by combining Vague set with the extension matter-element method.Finally,the authors use the combination of weighted Vague compound matter-element similarity and degree of grey relational,and measure the coefficient closeness degree between alternatives and positive-negative ideal solution.Objective evaluation results are obtained by means of a case study.It shows that this method can effectively evaluate the supportability of airplane and has practicality in improving the scientificity and accuracy of airplane supportability evaluation.
