基于多层次灰色综合评价法的工业设计方案优选决策模型及其应用

The optimal decision-making model of industrial design scheme based on multi-level grey comprehensive evaluation method and its application

为辅助企业在产品设计方案评估阶段进行合理地决策,减少设计的盲目性和主观性,基于多层次灰色综合评价法构建了工业产品设计方案优选决策模型。在评价流程中,首先依据层次分析法(AHP)与熵权法通过定性、定量分析,合理地进行评价指标权重系数的确定。其次,采用灰色关联度分析法对各设计方案进行灰色加权关联度的计算,确定其排序,并依据结果完成对设计方案的综合评价与优选工作。基于该模型完成了对某款多旋翼无人机的5个设计方案的优先级排序,并将结果依据熵权TOPSIS法进行验证,以证明其可行性。最后,基于指标权重与方案得分完成了对优选方案的优化,并对方案进行三维建模视觉化展示,有效地表明了基于多层次灰色综合评价法的无人机产品评价优选决策模型的设计辅助作用。

In order to assist enterprises in making reasonable decisions during the evaluation stage of product design schemes and reducing blind subjectivity of design,a decision-making model for selecting industrial product design schemes was constructed based on the multi-level grey comprehensive evaluation method.In the evaluation process,firstly,the weight coefficient of the evaluation index was reasonably determined through qualitative and quantitative analysis according to the analytic hierarchy process(AHP)and entropy method.Secondly,the gray correlation analysis method was adopted to calculate the gray weighted correlation degree of each design plan,the order of the design schemes was determined,and the comprehensive evaluation and selection of the design schemes were completed based on the results.Based on this model,the priority ranking of five design schemes of a certain multi-rotor UAV was completed,and the results were verified according to the entropy weight TOPSIS method,proving the feasibility of this model.Finally,based on the index weights and program scores,the optimization of the selected scheme was conducted,and the scheme was visualized by three-dimensional modeling.Thus,the role in design assistance of the decision-making model for evaluating and selecting UAV products,based on the multi-level gray comprehensive evaluation method,was effectively demonstrated.
