Usability Evaluation of Welding Clamp Based on Improved Fuzzy Synthetic Evaluation Model

摘要

Usability is the basic properties of the product, and it is the overall evaluation to the product usability. In this paper, firstly, establish a usability evaluation index system of the welding clamp. Then, use the improved fuzzy synthetic evaluation method to assess the usability of welding clamp. In an improved fuzzy synthetic evaluation model, the index weight which is identified by using AHP method is amended objectively by using entropy technology; the resolution ratio is improved by classifying the differences between qualitative indexes and quantitative indexes. Finally, get the evaluation results of the usability of a welding clamp according to the method above. The result is to some extent valuable, in terms of theoretical research, for improving the usability of welding clamp.
