基于VIKOR的轮式装载机配色设计与评价研究

Color Matching Design and Evaluation of Wheel Loader Based on VIKOR

目的将用户内隐的色彩意象感知进行外化并加以定量描述,减少由于多指标权重模糊造成的配色方案评价结果误差,保持设计与评价原则的一致性。方法结合因子分析-熵权法与多准则妥协解排序的配色设计与方案评价方法,运用德尔菲法等建立目标色彩意象词汇集,通过设定等距间隔在RGB参数值域内获取具备代表性的备选主色样本库;采用语义差异法构建评价矩阵,通过因子分析进行降维提取色彩因子,结合熵权法得到色彩意象评分模型,对各色彩样本打分后排序,获取备选主色库;以色相距离理论为依据形成辅助色选取原则;根据指标赋权后的VIKOR对多个备选方案评价,得到合理排序结果。结论以某型轮式装载机的涂装配色设计与方案评价进行了实例验证,结果表明这个研究方法在多配色方案评价时充分考虑了各指标信息量,有助于设计师深入挖掘用户潜在的色彩设计需求。

The work aims to externalize and quantitatively describe the user's implicit color image perception,reduce the error of color scheme evaluation result caused by multi-index weight blur,and maintain the consistency of design and evaluation principles.A color matching design and scheme evaluation method combining factor analysis-entropy weight method and multi-criterion compromise solution ranking was proposed.The Delphi method and other methods were used to establish a target color image vocabulary set and the representative alternative dominant color sample library was obtained from the RGB parameter range by setting equidistant intervals.The semantic difference method was used to construct the evaluation matrix,the factor analysis was carried out to extract the color factors,the color image scoring model was obtained by combining the entropy weight method,and the color samples were scored and ranked to obtain the alternative dominant color library.Based on hue distance theory,the auxiliary color selection principle was formed.According to the index-empowered VIKOR method,multiple alternatives were evaluated and reasonable ranking results were obtained.The color matching design and scheme evaluation of a certain type of wheel loader are verified by example,and the results show that this research method fully considers the amount of information of each index when evaluating multiple color matching schemes,which helps designers to dig deep into the potential color needs of users.
