Reliability Optimization Deploymentof Complex Electromechanical Equipment Based on Multi-objective Optimization Algorithm

In order to solve the problem of reliability deployment of complex electromechanical equipment, the functional relationships between the reliability and cost of each subsystem of complex electromechanical equipment are analyzed in this paper. Moreover, Pareto multi-objective optimization and improved Artificial Bee Colony algorithm were used to solve the reliability optimal configuration model to improve the reliability of complex electromechanical equipment and minimize the development cost, maintenance cost and total cost of the system.Eventually, according to the Pareto optimal solution set, the PROMETHEE-II method is used to optimize the reliability deployment scheme of the optimal solution set, and the comprehensive optimal system reliability deployment scheme is obtained. The effectiveness of the proposed method was illustrated by using an equipment example, and the results shown that the total cost of the system can be obviously reducedon the premise of meeting the reliability requirements of the system.
