摘　　要：铁路技术站的合理布局是铁路部门有效完成运输任务的基本保证,将技术站布局问题分解为技术站选址、技术站建设规模、车流组织优化3个相互关联的子问题,建立技术站布局的双层规划模型,通过对技术站选址方案的枚举和上、下两层规划的迭代求解,有效地将技术站布局问题转化为一系列相对独立的子问题来解决。实际应用表明,采用技术站布局的双层规划优化方法运算快捷,计算结果合理,对技术站布局提供了理想的决策支持。The rational layout of technical service station guaranteed the railway department to accomplish the transport task efficiently. In this paper, the problem of layout of technical service station was divided into three dependent subproblems--location of technical service station, construction scale of technical service station and wagon flow organizing. A bilevel programming optimization model for the layout of technical service station was established. Through enumerating the locating projects of technical service station and iteratively solving the problem between the upper programming and the lower programming, the problem of the layout of technical service station was effectively converted into a series of relatively independent subproblems. Practical applications denoted that the optimization method operated rapidly based on the bilevel programming and the calculated result was rational. It provided a perfect decisionmaking support method for the layout of technical service station.
