Application of Fuzzy Decision Model Selection of Product in Human Factors Design

The use of human-designed products places a greater emphasis on consumer constituents and often affects consumer preferences and purchase preferences for the overall shape of the product. The evaluation model proposed in this paper uses Fuzzy Analytic Hierarchy Process (FAHP) to obtain the degree of emphasis (weight value) of consumers on each evaluation item, and then obtain a more objective overall shape preference. In this paper, the electrotherapy designer is used as a research case. The results show that the evaluation model is indeed feasible, and the research results of this case are also valuable for subsequent designers. This evaluation mode is for products with different shapes, and subsequent researchers or designers can apply this method to different case designs.
