School of Construction Machinery, Chang'an University, Xi'an 710064, China
为有效融合工业设计方案决策中的异构信息, 引入云模型处理定性语言评价, 基于黄金分割方法将语言信息量化为云模型的数字特征, 分别构建语言值、区间数和实数相对优势矩阵。考虑决策过程的模糊性与不确定性, 将决策属性判断的自然语言采用区间标度量化, 构建非线性优化模型求解最优决策属性权重, 以最大似然估计实现群体决策的区间标度集结, 通过综合效用函数计算工业设计方案优劣。以某型指挥用控制台工业设计方案决策为例, 验证了所提方法能够有效融合异构决策信息, 辅助工业设计师和决策者准确把控意见并进行方案优选。
To effectively integrate the heterogeneous information in the decision-making of industrial design schemes, the cloud model was adopted to process the qualitative language evaluation. Based on the golden section method, the language information was quantified into the digital features of the cloud model, and the relative advantage matrix of language value, interval number and real number were constructed respectively. Considering the ambiguity and uncertainty of the decision-making process, the natural language of decision-making attribute judgment was quantified by interval scale, and a nonlinear optimization model was constructed to find the optimal decision-making attribute weight. The interval scale aggregation of group decision-making was realized by maximum likelihood estimation and a comprehensive utility function was utilized to calculate the pros and cons of industrial design schemes. Taking the industrial design scheme decision making of a certain type of command console as an example, it is verified that the proposed method can effectively integrate the heterogeneous decision-making information, and assist the industrial designers and decision-makers to accurately control opinions and make scheme optimization and selection.
