基于F-AHP在坐躺两用办公椅设计中的应用研究

Application of F-AHP in the Design of Sitting and Lying Office Chairs

目的利用F-AHP(模糊运算综合评价法与层次分析法,Fuzzy Comprehensive Evaluation Method and Analytic Hierarchy Process,简称F-AHP)相结合,对坐躺两用办公椅进行综合分析评价,从而设计出满足用户实际需求的产品。方法通过层次分析法将用户的主观感受这种模糊的概念定性定量化,将产品可用性作为评价的重要指标,基于问卷结果对其进行分类为便捷性、舒适性、前卫性、科学性4个方面,构建层次分析体系,通过收集专家及用户的评分最终计算出各项设计评价指标的权重,并使用模糊综合评价法对办公椅的设计方案进行分析,得出最佳设计方案,最后运用JACK软件创建数字人物模型进行受力舒适度的测验结果分析。结果通过层次分析法和模糊运算综合评价法在产品设计过程中的应用,对用户在不同工作状态下设计的坐躺两用办公椅方案具有一定的参考价值。结论通过对坐躺两用办公椅的设计案例,科学全面地证实了层次分析法和模糊运算综合评价法的结合在产品设计过程中具有实用性和可靠性,可有效指导办公椅的创新设计过程。

Using F-AHP(Fuzzy Comprehensive Evaluation Method and Analytic Hierarchy Process,F-AHP)to comprehensively analyze and evaluate the sitting and lying dual-purpose office chairs,so as to design products that meet the actual needs of users.Through the analytic hierarchy process,the vague concept of user’s subjective feeling was quantitatively and qualitatively,and product usability was regarded as an important indicator of evaluation.Based on the results of the questionnaire,it was classified into four aspects:convenience,comfort,avant-garde,and scientificity.,Build an analytic hierarchy system,finally calculate the weight of each design evaluation index by collecting the scores of experts and users,and use the fuzzy comprehensive evaluation method to analyze and evaluate the design plan of the office chair to get the best design plan,and finally use JACK The software creates a digital character model to analyze the test results of force comfort.Through the application of analytic hierarchy process and fuzzy comprehensive evaluation method to the product design process,the project of sitting and lying dual-purpose office chairs designed according to the user's needs under different working conditions has certain reference value.Through the design case of the sitting and lying dual-purpose office chair,it is scientifically and comprehensively confirmed that the combined use of the analytic hierarchy process and the fuzzy comprehensive evaluation method is practical and reliable in the product design process,and can effectively guide the office chair.Innovative design process.
