Inspection plan prediction for multi-repairable component systems using neural network
英文摘要：
Implementing an appropriate maintenance policy would help us to have a more reliable system and reduce the total costs. In this paper, a dynamic maintenance plan is proposed for repairable multi-component systems, where each component is subject to two competing failure processes of degradation and random shock. For systems with individually repairable components, it is not economical to replace the whole system if it fails. At any inspection time, the failed components can be detected and replaced with a new one and the other components continue functioning; therefore, the initial age of each component at any inspection time is different from other components. Different initial ages have an effect on the optimal time that the whole system should be inspected. The optimal inspection time should be calculated dynamically considering the initial age of all the components and their configuration within the system. In this paper, a neural network method is used to predict the next optimal inspection time for systems considering the initial age of components at the beginning of the inspection. System reliability and cost rate function are formulated and used to train the prediction model. The proposed maintenance plan is demonstrated by numerical examples
