基于熵权—VIKOR法的椅类家具舒适性设计评价

Evaluation of Chair Furniture Comfort Design Based on Entropy Weight-VIKOR Method

目的为了解决椅类家具舒适性设计评价过程中主观赋值的模糊性、不确定性及主观与客观结合时的权重比例的分配不合理所造成的评价结果的较大误差,为椅类家具设计提供更为客观且简单易用的评价方法。方法运用用户体验理论和FFORDANCE理论构建较为科学和全面的椅类家具舒适性设计评价指标体系;利用熵权体系排除决策者在赋权中的主观因素并利用VIKOR法最大化群体效用使评估者接受其折衷解,将熵权法和VIKOR法相结合解决椅类家具设计方案的优选问题。结论通过椅类家具中办公座椅舒适性设计方案的评价过程及结果验证了熵权—VIKOR法能够解决现有设计评价方法主观赋值存在的问题,实现了评价过程的客观化和定量化。

To solve the large evaluation result error caused by the fuzziness and uncertainty of subjective evaluation and the unreasonable weight proportion of subjective and objective factors in the evaluation process of chair furniture comfort design,a more objective and easy-to-use evaluation method is provided for chair furniture design.The user ex-perience theory and Affordance theory are used to build a more scientific and comprehensive evaluation index system for chair furniture comfort design.Theentropy weight system is usedto eliminate the subjective factors of decision-makers in empowerment and the VIKOR method is used to maximize group utility to make the evaluator accept its compromise so-lution,and then the entropy weight method and the VIKOR method are combined to solve the optimization problem of chair furniture design scheme.Through the evaluation process and results of the office chair comfort design scheme,it is verified that entropy weight-VIKOR method can solve the problems of subjective evaluation of existing design evaluation methods,realizingan objective and quantitative evaluation process.
