In this paper, all kinds of effects which influence the quality of mechanical assembly sequences, were analyzed in detail. Then based on fuzzy theory a two-level method for overall fuzzy evaluation of mechanical assembly sequences was presented. A numerical example is given, it shows that our methed is reasonable and reliable.%针对机械装配序列的特点,基于模糊数学理论,分析了影响装配序列品质的各种因素,提出了针对装配序列的二级模糊综合评判过程的实现方法。
