| Abstract: | The joint optimization of condition-based maintenance and spare part inventory is an effective method to ensure the safety operation of key components in equipment and reduce maintenance support costs. In order to solve the problem that the existing models ignore the effects of random shock in complex environments, a joint optimization model of condition-based maintenance and spare part inventory for multi-component system considering random shock effects is proposed. Firstly, the degradation model and the reliability model under random shock are established. In the sense of the first hitting time, the probability distribution of the remaining useful life is derived using the idea of threshold conversion, and the degradation model parameters are estimated by the maximum likelihood method. Then, the joint policy of condition-based maintenance and spare part inventory is formulated, and the joint optimization model is established with the target of the lowest average cost ratio. Meanwhile, particle swarm optimization and Monte Carlo simulation are used to solve this model. Finally, the validity and application value of the proposed model are verified through an example analysis and sensitivity analysis. |
