主要内容:

Disruptions and delay are very common and frequent in the day-to-day train operation. To mitigate disruptions and reduce delay, train movement in the railway network needs to be rescheduled ad hoc and in real time. Besides delay, energy consumption is also an important concern of railway managers and train operators, and another effective tool to manage the usage of time and energy is the advisory speed profile (ASP). ASP is a collection of reference speeds at different locations of the train journey provided to the train drivers. By closely following the ASP using appropriate traction and braking, the train can adhere to the predetermined schedule and save energy. This talk will start with an overview on the railway planning and operation procedure, and then focus on train rescheduling and ASP design, including: (i) their concepts, mathematical models and solution methods; and (ii) our recent progress in: rescheduling with advanced information on weather-induced speed limit reduction, the ASP design for single and multiple trains, as well as the integration of scheduling and ASP design.

延误和能耗是铁路管理者和运营者关注的重要问题。干扰和延误普遍存在于列车日常运营中;为了降低延误的影响,需要通过调度来实时调整列车运行图。除实时调度外,管理延误和能耗的另一个有效手段是节能速度曲线。通过采用适当的牵引和制动来准确跟踪节能速度曲线能保证列车准点到站并降低能耗。本次讲座将简要介绍铁路规划和运营流程,并重点介绍列车调度和节能速度曲线设计问题,包括:(一)概念、数学模型和解法;(二)一些最近的研究进展,包括基于天气预报信息的实时调度,单列车和多列车的节能速度曲线设计,以及运行图和速度曲线的联合优化。
