Abstract:

Carrying out reliability evaluation of equipment system has important engineering application value for ehhancing performance, improving efficiency, and reducing management and control risks. Aiming at the large-scale complex equipment system, by constructing limit sequence kernel and limit reliability approximation function for different coupling structures, a multi-state reliability modeling, analysis, and fast evaluation method with low requirement of calculation resources, calculation convenience, and approximation accuracy meeting the needs of engineering is explored. The case study shows that the algorithm breaks through the bottleneck of large-scale reliability calculation technology of complex equipment system, improves the efficiency of reliability evaluation, and has good effect in evaluation and risk prediction. Moreover, the algorithm enriches the multi-state reliability modeling, analysis, and evaluation system of complex equipment system, which can provide advanced theoretical reserves and engineering technology reference for reliability engineering design, use, and management personnel.

Key words: large-scale system, limit sequence kernel, multi-state, reliability evaluation, fast algorithm
