Reliability analysis of hydraulic transmission oil supply system considering maintenance correlation of parallel structure based on GO methodology

A new reliability analysis method for repairable systems with closed‐loop feedback links

“…The fault modes of the units are determined according to statistical analyses of engineering data, as presented in Table , and the fault rate and maintenance rate of each fault mode in the PSSTCS are presented in Appendix I. According to the availability formulae for fault mode units, the availabilities of units at different times are presented in . 2Calculating the reliability parameters of CLFL for the PSSTCS …”

“…In order to improve the accuracy of GO operation, Shen et al presented an exact algorithm with shared signals . Subsequently, Yi et al employed 3 types of GO operation algorithm to conduct reliability analysis for some engineering systems and found that the result obtained by the exact algorithm with shared signals was closer to the true value . Industrial engineering systems and their components are usually repairable, so Shen et al applied the GO method to repairable systems.…”

“…There are often multiple fault modes for components in repairable systems, eg, the components of a hydraulic system can have 1 to 4 failure mode types . Yi et al developed a new GO method for the reliability analysis of repairable systems with multiple fault modes, and the reliability analysis result was shown to be more accurate . Moreover, all the fault‐mode‐level minimum cut sets of a system can be obtained quickly with this GO method.…”

“…21 Subsequently, Yi et al employed 3 types of GO operation algorithm to conduct reliability analysis for some engineering systems and found that the result obtained by the exact algorithm with shared signals was closer to the true value. 22,23 Industrial engineering systems and their components are usually repairable, so Shen et al applied the GO method to repairable systems. They also discussed some correlation problems, such as the correlations with stopping work, maintenance, and standby, and deduced the reliability characteristics formula for a seriesparallel structure with correlations by combining the state transition rate concept with the equivalent ideology.…”

A new reliability analysis method for repairable systems with multifunction modes based on goal‐oriented methodology

“…Thus, a modified algorithm with shared signal and an exact algorithm with shared signal were proposed . Later, the reliability analysis of some engineering systems was conducted based on the above 2 kinds of GO algorithms, and the result of the exact algorithm with shared signal was shown to be closer to the true value . In addition, the GO algorithm can be developed by combining with other technologies to solve special engineering problems, such as the GO‐FLOW methodology, the improved GO algorithms combined with gray theory, matrix operation, and fuzzy mathematics …”
