Integrated Optimization of Condition-Based Maintenance and Spare Parts Management for Offshore Wind Turbines
Maintenance activities of offshore wind turbines are usually centralized due to the severe weather and expensive sailing cost, which puts forward higher requirements for the spare parts inventory management of offshore wind turbine components. Based on this problem, this paper presents an integrated model for condition-based maintenance and spare parts management. It significantly reduces the failure time of the wind turbine and reduces the shutdown loss. Taking the inspection cycle of offshore wind turbine, the maintenance threshold of components, the reorder point and the order quantity of spare parts as the joint decision variables, a mathematical model with the objective of minimization of cost rate is established. Due to the high complexity resulting from random variables as well as coupling relationship between maintenance and spare parts management, Monte Carlo simulation algorithm is designed to estimate the objective value of the model. Finally, the simulation based sensitive analysis experiment shows the effectiveness of the proposed model and algorithm.
