Condition-Based Maintenance Modeling and Reliability Assessment for Multi-Component Systems with Structural Dependence under Extended Warranty

For engineering and production systems, due to the structural dependence between components, disassembly operation caused by replacement of components will affect failure degradation processes other in system. In order optimize extended warranty (EW) cost multi‐component system with dependence, this paper described modeled impact, then rate model component considering impact under EW was developed. Combined actual situation, a condition-based maintenance (CBM) strategy employed construct dependence. Monte Carlo simulation proposed determine optimal periodic inspection interval CBM strategy. Finally, numerical example planetary gear train an automobile generator is introduced demonstrate feasibility advantages optimization analysis on
