【摘要】：随着国家经济的不断发展和小件货物运输市场的竞争日趋激烈,铁路行包运输作为小件行包运输的中坚力量,正在面临新形势、新机遇的挑战。在铁路行包运输调度现代化、市场化的大背景下,以往的以人工经验为主的行包调度模式亟待改变。研究如何将铁路行包运输调度从生产型调度向经营型调度转变,实现对内管理和对外服务的双赢具有重要的现实指导意义。本文以铁路行包运输调度的指挥体系和调度过程为研究对象,结合铁路行包运输基本装运原则,研究了三级调度体系的职能和相互关系的优化,并从装运实施方案的优化出发,重点研究了直达行包和中转行包装运组织的调度优化问题。首先,基于现有铁路行包调度体系结构和职能,深入分析了行包调度指挥的业务流程和管理流程,提出了调度优化的必要性和主要优化问题。其次,针对行包调度指挥存在的主要问题,从统计分析、监控预警、运能调配三方面对三级调度部门职能分别优化。在此基础上,运用系统优化理论优化了调度信息传递流程,并给出了行包调度指挥信息平台初步架构。然后,针对直达行包装运实施问题,从直达装运车次的优化选择和分车次装车计划调度调整两方面进行优化。在分析装车计划调整的影响因素基础上,构建了分车次调度调整优化模型,以解决在装运行包广义收入最大的优化目标前提下,同时兼顾货物装运优先等级的问题。运用lingo12.0编程求解案例,给出各站实际装车计划调整结果。最后,针对中转行包装运调度的决策,给出中转装运车次的衔接优化选择策略。通过中转决策指标体系的架构,依托模糊数学思想,提出了运用改进的多级模糊综合评价方法来辅助决策,并结合大客户行包转运实例验证了此方法的科学性。
[Abstract]:With the development of national economy and the increasingly fierce competition in the market of small goods transportation, railway luggage and parcel transportation, as the backbone of small package transportation, is facing the new situation, new opportunities and challenges. Under the background of the modernization and marketization of railway luggage and parcel transportation scheduling, the former manual experience oriented luggage and parcel scheduling mode needs to be changed urgently. It is of great practical significance to study how to change the dispatching of railway luggage and parcel transportation from production dispatching to management scheduling, and to realize the win-win situation of internal management and external service. This paper takes the command system and dispatching process of railway luggage and parcel transportation as the research object, combining with the basic shipping principle of railway luggage and parcel transportation, studies the optimization of the function and interrelation of the three-level dispatching system, and proceeds from the optimization of the shipping implementation scheme. This paper focuses on the scheduling optimization of direct package and transit package shipping organization. Firstly, based on the existing railway packet scheduling architecture and functions, the business process and management flow of the packet scheduling command are analyzed, and the necessity of scheduling optimization and the main optimization problems are put forward. Secondly, aiming at the main problems existing in the dispatch and command of luggage and parcel, the functions of the three-level dispatching department are optimized from three aspects: statistical analysis, monitoring and warning, and transportation capacity deployment. On this basis, the system optimization theory is used to optimize the flow of dispatching information transmission, and the preliminary framework of the packet scheduling command information platform is given. Then, aiming at the implementation of direct luggage and parcel shipment, the paper optimizes the selection of direct shipment number and the scheduling adjustment of train loading schedule. Based on the analysis of the factors affecting the adjustment of the loading plan, the optimization model of the scheduling adjustment by train is constructed to solve the problem of taking account of the priority grade of cargo shipment under the premise of the optimization goal of the largest generalized income of the shipment luggage and parcel at the same time. By using lingo12.0 programming to solve the case, the adjustment results of actual loading plan of each station are given. Finally, according to the decision of the dispatch of transshipment, the optimal selection strategy is given. Based on the framework of transshipment decision index system and the idea of fuzzy mathematics, an improved multilevel fuzzy comprehensive evaluation method is put forward to assist decision making, and the scientific nature of this method is verified by the example of large customer package transshipment.
