机械类运动器械设计性能模糊综合评价

Fuzzy Comprehensive Evaluation on Design Performance for Enginery Sports Equipment

针对当前机械运动器械设计与生产存在的问题,运用模糊综合评价方法对设计性能进行评价。首先,将前人的研究成果进行整理,以表格的方式列出了评价指标体系及其权重;然后,按照单指标模糊评价、模糊综合评价、评价准则确定3个步骤建立评价数学模型;最后,进行了评价实例分析。结果表明,评价结果主要受评价指标体系及权重、单因素评价、评价准则选择等方面的影响,实际应用时要引起足够的重视。

For the current problems in designing and producing enginery sports equipment,we can use fuzzy comprehensive evaluation method to evaluate its design performance.First,the previous research results are sorted out,evaluation indicator system and its weight can be listed in tabular form;then,evaluation of a mathematical model was established according to three steps,such as single indicator fuzzy evaluation,fuzzy comprehensive evaluation,the determination of evaluation criteria;finally,an evaluation case study was carried out.The results show that the evaluation indicator system,weight,single factor evaluation and the selection of evaluation criteria mainly affect the evaluation results,so it must be attached much significance in the actual application.
