【摘要】：为充分体现新产品开发方案选择决策过程中决策者的主观偏好对决策结果的影响,提出基于决策者方案偏好的新产品开发方案选择方法。鉴于方案选择过程中信息的模糊性和不确定性,评价指标属性值以区间数形式给出,以减少决策信息的丢失。利用向量规范化方法规范化评估团体决策矩阵;通过企业内决策者给定其对备选方案的主观偏好值,并引入修正系数进行修正;通过区间数相离度获取使评估团队与决策者偏好总偏差最小的属性最优权重向量;集结属性权重向量和规范决策矩阵,得出各备选方案的综合属性值;通过两两比较区间数形式的综合属性值,建立可能度矩阵并计算其排序向量进行方案的排序择优。应用实例及案例对比分析表明,该方法对新产品开发方案选择是有效且可行的。
[Abstract]:In order to fully reflect the influence of the decision makers' subjective preferences on the decision results in the process of selecting new product development schemes, a new product development scheme selection method based on the decision makers' preference is proposed. In view of the fuzziness and uncertainty of information in the process of scheme selection, the attribute value of evaluation index is given in the form of interval number to reduce the loss of decision information. The method of vector normalization is used to normalize the evaluation of group decision matrix, and the subjective preference value of the decision maker to the alternative scheme is given by the decision maker in the enterprise, and the correction coefficient is introduced to correct the matrix. The optimal attribute weight vector with minimum bias between evaluation team and decision maker is obtained by interval number divergence degree, attribute weight vector and canonical decision matrix are assembled, and the comprehensive attribute value of each alternative scheme is obtained. By comparing the comprehensive attribute values in the form of interval numbers by pairwise comparison, the possibility degree matrix is established and its sorting vector is calculated to select the priority of the scheme. The application examples and case studies show that this method is effective and feasible for the selection of new product development schemes.
