摘要
针对编组站运营系统仿真研究中的关键仿真控制方法——前向环馈仿真方法(Forward Feed-CircleSimulation,FFCS)的相关理论、模型及实现技术进行研究。FFCS的核心思想是在仿真过程中引入虚拟仿真计算概念,虚拟仿真推进计算循环中的每一步计算结果都馈送到下一步,形成闭合循环。利用FFCS方法进行仿真分为基准计算、虚拟仿真推进、匹配计算和调整量计算4个步骤,并在方法的实现过程中采用作业节点、作业链模型和神经网络算法。通过对一个典型的单向三级三场编组站到解系统进行示例仿真计算证明:FFCS方法与传统仿真相比,虽然计算量和计算耗时大,但其仿真结果的适应性以及对外部扰动的适应能力强,较好地解决了传统仿真方法不能有效利用预确报信息的不足。
The paper studies on the relative theory, model and realizing technic of the marshalling station operation system's key simulation method-Forward Feed Circle Simulation (FFCS). The kernel ideas of FFCS are importing virtual simulation calculation concept in simulation process. In the circle of virtual simulation calculation, each calculation result is fed to next step and shaped into a closed circle. The FCFS can be divided into four steps: base time calculation, virtual simulation process, matching calculation and adjustment calculation. In the realizing process of the FCFS, job point, job chain model and neural network algorithms are adopted. Through a typical FCFS simulation example, we found the FFCS has strong adaptability against the environment disturbance. The FFCS could solve the problem of the generic simulation method which can not use the forecast information of marshalling station.
