摘　　要：基于可靠性理论和优化理论,以解决车辆维护与修理混合决策为目的,将今后一定时间段内预期总费用最低设为优化目标,采用定量方法进行分析,建立数学模型。结合具体的车辆技术状况概率和费用数据,给出了计算实例。研究成果具有重要的理论意义和工程应用价值,对改进公路运输企业的维修管理水平,提高成本效益具有积极的意义。Based on reliability theory and optimization theory, with the purpose to solve the mixed decision problem of vehicle maintenance and repair, the optimization goal was to make the expected total cost lowest in a certain future period of time, and the quantitative methods was used to analyze, at last the optimal mathematical models were established. Combined with the specific technical condition probability of vehicles and cost data, calculation examples are given. The research has important theoretical significance and engineering practical value, and it is of positive meaning to improve the maintenance management level, and to increase cost-effectiveness of road transport enterprises.
