基于层次分析法和感性工学的工程车造型设计评价

Evaluation of Engineering Vehicle Design Based on AHP and KE Method

目的为了客观评价工程车造型中人为感性情感带来的模糊和不确定性因素,寻求一种科学的工程车造型设计评价方法,并对工程车造型设计各方案进行有效评价。方法提出以层次分析法(Analytic Hierarchy Process)和感性工学(Kansei Engineering)相结合的评价方法,并将其应用于工程车设计的造型意象评价中。通过感性工学量化造型意象词汇,并确定目标意象词汇,采用层次分析方法建立造型特征与意象词汇之间的关系模型,构建影响造型意象评价的指标体系,建立模糊综合评价矩阵,计算各评价指标权重并进行综合排名。结论将该评价方法应用于四款水泥搅拌工程车造型设计方案评价中,运用模糊隶属度函数,建立了模糊综合评价矩阵,并对各个指标的评价结果进行了量化处理,筛选出最佳造型设计方案,为项目开发提供有效参考。

The work aims to find a scientific evaluation method of engineering vehicle design,to objectively evaluate the fuzzy and uncertain factors brought about by human perceptual emotions in the design of engineering vehicles and evaluate the various design schemes of engineering vehicles effectively.The evaluation method combining AHP and KE was proposed and applied to the evaluation of modeling image in engineering vehicle design.The modeling image vocabulary was quantified through KE to determine the target image vocabulary.The analytic hierarchy process was adopted to establish the relationship between modeling features and image vocabulary,build an index system that affected the evaluation of modeling image,construct a fuzzy comprehensive evaluation matrix,calculate the weight of each evaluation index and conduct comprehensive sorting.The evaluation method is applied to the evaluation of the design schemes of four cement mixing trucks.The fuzzy membership function is used to establish the fuzzy comprehensive evaluation matrix,and the evaluation results of each index are quantitatively processed to obtain the best design scheme,providing an effective reference for project development.
