石油机械可靠性指标的模糊决策

利用二级模糊综合评判原理对无游梁式抽油机曲柄销的可靠度进行预测。由于影响曲柄销工作可靠性的因素较多，而且多数因素具有模糊性，因此利用此法预测的结果会更加接近实际，避免常规可靠性预计技术的复杂性、盲目性以及数据收集上的困难。

Using the two - level fuzzy comprehensive theory for the realibilty testing of the crank pin in the non - beam pump is discussed in this article. Because there are several factors influencing the realibility of the crank pin,and the factors are fuzzy,so the application of this prediction is closer to the real situation.This can avoid the technlolgy complexity,blindness and the difficulty for data collection in the conven- tional realibility prediction.
