摘要
在概念设计阶段中,机械运动方案的选择和评价是较为重要的。本文针对此阶段评价因素既有模糊性又分层次的特点,提出了较为适合的三级模糊综合评价方法,把人的主观因素限制在较小的范围内,在解决了因素权分配的困难和评价结果近似相等的不足的同时,保证了评价结果的准确性。最后,本文用一个例子说明了三级模糊综合评价在机械运动方案设计专家系统中的应用。
It is very importanat that making selection and decision of mechanism scheme at conceptual design stage.Dealing with the fuzzy and multi layer characteristics of decision factor in this stage,a model for mechanism scheme using three grade fuzzy synthetical decision method is described.A solution is worked out for the difficulty in distribution of weights and shortage in specification of schemes.At last,a example is given to illustrate the application of expert system of mechanism scheme using this method.
