| 某商用洗碗机存在产品设计评估范围精准性差及应用有局限性等缺点，课题组提出了基于FTA和FMEA的模糊评估模型，同时以喷淋结构设计评估为示例验证。课题组所提出的评估方式采用梯形模糊数为严重度、发生率和探测度来定义评级标准，并引入矩阵法来衡量FMEA风险排序；通过数据累加将相关联的潜在失效模式定位至产品设计关键部件。示例评估结果与实际情况符合。课题组所提出的评估模型对商用洗碗机关键硬件设计评估是准确而有效的，可推广至其它产品硬件设计质量评估，帮助企业高效完成产品设计评估。 |

| Research projects′ group took the evaluation of key hardware design of a commercial dishwasher as the research object. Considering the shortcomings of poor accuracy and limited application of product design evaluation scope at present, a fuzzy evaluation model was put forward based on FTA and FMEA, and spray structure design evaluation was taken as an example to verify. Due to the poor accuracy, lack of logical rules, low sensitivity and repeatability of risk priority RPN ranking in FMEA, the evaluation method proposed in this paper used trapezoidal fuzzy numbers S, O, D to define the rating standards, and matrix method was introduced to measure FMEA risk ranking, and the associated potential failure modes were located to the key components of product design through data accumulation. The evaluation result of the example is in accordance with the actual situation. Therefore, the evaluation model proposed in this paper is accurate and effective for evaluating the key hardware design of commercial dishwashers, and can be extended to other products to evaluate the quality of hardware design and help enterprises effectively complete product design evaluation. |
