摘　　要：方案评价是产品服务系统设计的关键环节之一,评价结果的合理性对企业发展至关重要。基于最小平方和法,构建了云-TOPSIS-灰关联分析模型,对产品服务系统方案进行评价。引入云模型和相对偏好关系量化离散型指标,解决专家评价的模糊性和随机性问题。运用TOPSIS灰关联分析法确定正、负理想灰关联系数矩阵,集成指标权重和正、负理想灰关联系数矩阵建立正、负理想加权灰关联系数矩阵,兼顾了几何方案序列曲线的位置接近度和形状相似度。运用最小平方和法求解灰关联投影系数,确定方案排序。以某农业装备企业拖拉机产品服务系统方案评价为实例,验证了所提模型的科学性和可行性。Scheme evaluation is one of the key links of product service system design.The rationality of evaluation results is very important for the development of enterprises.Based on the least sum of squares method,cloud-TOPSIS-grey correlation analysis model is constructed to evaluate the product service system scheme.Cloud model and relative preference relation were introduced to quantify discrete indexes to solve the problems of fuzziness and randomness in expert evaluation.The positive and negative ideal grey association coefficient matrices were determined by TOPSIS grey association analysis method,and the positive and negative ideal grey association coefficient matrices were established by integrating index weights and positive and negative ideal grey association coefficient matrices,taking into account the position proximity and shape similarity of corresponding geometric scheme sequence curves.The least sum of squares method was used to solve the grey correlation coefficient and determine the scheme ranking.Taking the project evaluation of tractor product service system in an agricultural equipment enterprise as an example,the science and feasibility of the proposed model were verified.
