In view of the The paper introduces the definition of simulation reliability,which overcomes the limitation of the standard deviation in the risk analysis,to analyze the risk of the plans with different expectation,and provides a basis for the maintenance plans risk analysis and decision.

These methods are validated with reliability simulation software and are useful for improving the HCE performance of CMOS digital integrate circuit.

The Optimal Tolerance Distributing of Assemble DimensionalChains Based on Value Engineering and Fuzzy Reliability;

Researches on the Fuzzy Reliability of the Petroleum Pipeline Systems;

On calculation of random-fuzzy reliability of the slope with circular sliding surface;

The fuzzy probability of two typical structures in geomechanics engineering,underground diaphragm wall and retaining wall,is calculated by three representational membership functions and a probability density function for the performance function.

The calculation method of fuzzy probability is found by using some theory and methods of fuzzy mathematics.

The method used in the paper is also applied to research the fuzzy probability of other type of fuzzy restriction conditions in fuzzy probability optima.

The concept and the character of cutting tool reliability and the reliability model of NC cutting tools are presented.

Based on the establishment of the reliability model for the Cold Standby system, the approximation algorithm on the calculation of the system reliability is first worked out; the confidence lower limit of the system reliability is then calculated by using WCF method and Fiducial method; and the Bayes estimation and the multiple Bayes estimation of the system reliability are finally discussed.
