     天然气管道故障率随运行时间的增加而不断增加,传统的等周期预防性维修无法满足天然气管道失效特性,为提高天然气管道的安全性,开展对弹性维修周期模型的研究。既要提高系统的可靠性,又要控制维修成本,将天然气管道的可靠性和天然气管道维修的经济性结合起来,根据系统故障率的变化,运用预防性维修的相关理论,引入役龄回退因子建立系统可靠性-维修成本多目标优化模型。结合具体的工程实例,在MATLAB平台下,应用多目标粒子群优化算法对模型的具体算例进行求解,得到以可靠性和经济性为目标的弹性预防性维修周期,为企业天然气管道的维修管理提供理论依据。 The failure rate of natural gas pipeline increases with the running time, the traditional periodic preventive maintenance can not meet the natural gas pipeline failure characteristics, in order to improve the safety of natural gas pipeline, to carry out the study of the elastic maintenance cycle model. It is necessary to improve the reliability of the system, but also to control the cost of maintenance, the reliability of natural gas pipeline and natural gas pipeline maintenance of the economy together, according to the system failure rate changes, the use of preventive maintenance of the relevant theory, Factor build system reliability - maintenance cost multi - objective optimization model Combined with specific engineering examples, in the MATLAB platform, the application of multi-objective particle swarm optimization algorithm to solve the specific examples of the model, to reliability and economy as the goal of the elastic preventive maintenance cycle for the enterprise natural gas pipeline maintenance management Provide theoretical basis.
