中文摘要：

为有效处理维修方式决策的众多影响因素间错综复杂的依存与反馈关系,并保证权重分配的客观合理性,通过总结现有的牵引供电系统维修方式及其优缺点,建立维修方式决策影响因素集并梳理因素间的依存与反馈关系,提出应用网络分析法（ANP）建立维修方式的ANP决策模型,逐步求取客观的维修方式综合权重并确定维修方式的优先顺序。结果表明,该方法能根据每段牵引供电系统的运行特点和对影响因素的实际需求合理地分配权重,最终定量给出维修方式的优先顺序,为后续高铁牵引供电系统维修维护成套化解决方案的研究奠定理论基础并提供数据依据。

英文摘要：

In order to effectively deal with intricate relationship of interdependence and feedback among the numerous influence factors of maintenance mode decision,and to ensure the objective rationality of weight allocation,existing maintenance modes for traction power system were summarized with their merits and demerits.Influence factors set of maintenance mode decision was established to analyze interdependent and feedback relationships among the factors.The Analytic Network Process（ANP）was presented for the building of ANP decision-making model to figure out objective overall weight of maintenance modes and to determine the priority of several maintenance modes.Results of practical example showed that the method can reasonably allocate the weight,based on operation characteristics of each section of traction power system and practical demand for influence factors,and finally and quantitatively determined the priority of maintenance modes which can lay theoretical foundation and provide data support for complete set of maintenance solutions of traction power supply system of high-speed railway.
