Based On Mixed Logic Dynamic Passenger Train Scheduling Research

Railway is the main artery of the country，the train operation dispatching isthe commander-in-chief of the train safety exercise，is the key of the wholerailway transportation. With the rapid development of railway construction inour country，the continuous improvement of passenger trains running speed，partof the railway line to overload，to implement the intelligent of the schedulingbecomes must to railway safety. Train operation dispatching involves train,people, roads, environment and many departments of railway transportation,contains both continuous subsystem and discrete subsystem, and the twosubsystems interact with each other, influence each other, is a typical hybridsystem. Train scheduling problem are also a multi-objective dynamic schedulingproblem. For this dynamic mixed characteristics of train operation dispatching,this paper adopts the mixed logical dynamic theory research driving schedulingproblem, not only provide new ideas for dispatching, but broaden the applicationfields for hybrid theory. This paper involves the MLD modeling, model analysis,and the Matlab simulation, etc.The main research works of this article as follows:1）A brief analysis of the background of driving scheduling problem, anoverview on the train scheduling research methods and research achievements inthe domestic and abroad，mixed logical dynamical theory is introduced to thestudy of the scheduling problem，laying the groundwork for the next step work.2）This paper introduces the basic theory of the mixed logical dynamic，mainly contains the logical proposition conversion relationship between Booleanfunctions with integer linear inequalities，expounds the MLD general modelmodeling steps, and finally analyzes using simple examples.3）Through the analysis of the train operation dispatching process, trainoperation dispatching is analyzed with the mixed dynamic characteristics of theprocess, it was pointed out that the essence of the train operation dispatching; And the switch, adjust the reason, the train characteristics, influencing factorsare summarized.4）Summarizes above, set up MLD train operation dispatching model andanalysis, further illustrate dispatching in the hybrid characteristics.5）Simulation with Matlab tools, and through the simulation results,combined with model analysis test, show that the model has a certain feasibility.
