Popis: A reliability optimization design method based on the goal-oriented (GO) method is proposed in this study to tackle the problem of engine reliability optimization design. This proposed method considers a V-type diesel engine as the research object. Firstly, the reliability modeling and evaluation of diesel engines are conducted by the GO method. Secondly, the functional reliability is assigned according to the difference in diesel engine function. Finally, a three-objective diesel reliability optimization design model is constructed with the optimization objectives of maximizing robustness and reliability and minimizing cost. Then, an NSGA-II-PSO hybrid algorithm based on the GO method is designed to handle the problem, and the design interval of unit reliability is obtained. The results of the case study demonstrate that this method not only meets the requirements of reliability design but also achieves the purpose of reliability optimization design, providing a reference for other types of equipment.
