Conventional reliability research on hydraulic system in recent years was reviewed, mainly including the reliability design, the reliability analysis and the reliability test etc. The limitations of conventional reliability theory were also pointed out and three branches of fuzzy reliability theory were expounded. Research progresses of fuzzy fault tree analysis, fuzzy reliability assessment were summarized. The development trend of fuzzy reliability technology of hydraulic system was finally forecasted.
