Abstract:
Considering the economic dependence among maintenance activities, the optimization of condition-based maintenance(CBM)for multi-component system was studied. The stochastic process was used to describe components’ performance degradation of components and the periodic inspection is adopted. At each inspection point, minimal repair, preventive maintenance or corrective maintenance were adopted for different components based on their degradation state. The long-time running average cost rate model of CBM was established based on renewal process, and maintenance optimization model of multi-components was built by considering the economic dependence among the components. A multi-component system of wind turbine was selected as a case, which is composed of main shaft, gear box and generator, etc. The optimal inspection period is studied, and the effects of model parameters on the maintenance cost and decision were analyzed. The results show that the proposed model can describe the maintenance optimization problem of multi-component system considering economic dependence among the components. Thus, it is beneficial to reduce the maintenance cost.
