Railway cargo whole-process transportation plan compiling method

Abstract

The invention discloses a railway cargo whole-process transportation planning method, which comprises the steps of setting basic input, constructing a space-time service network, and constructing a railway cargo whole-process transportation planning model based on the basic input and the space-time service network, and generating a railway cargo whole-process transportation plan based on the railway cargo whole-process transportation plan making model,. According to the railway cargo whole-process transportation plan generation method and system, transportation resources are fully utilized, the quality and efficiency of transportation organizations are improved while freight tasks are achieved, and the deadline redemption rate of cargo transportation is increased.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a method for formulating a whole-process transportation plan of railway cargo. Background technique [0002] For the preparation of railway freight transportation plans, domestic practice usually adopts manual preparation, based on the freight demand in experience, and on the basis of existing train formation plans and train operation diagrams, the preparation of daily freight schedules is realized. However, due to the lack of consideration of the time limit for goods delivery in the preparation of the train formation plan, and the lack of integration of goods flow, trains, and operating lines, the fulfillment rate of the time limit for goods delivery is low, and it is difficult to adapt to the rapid development of the logistics market. Demand for high-level rail freight transport. The current railway freight transportation planning mainly faces the following problems: ...

Problems solved by technology

However, due to the lack of consideration of the time limit for goods delivery in the preparation of the train formation plan, and the lack of integration of goods flow, trains, and operating lines, the fulfillment rate of the time limit for goods delivery is low, and it is difficult to adapt to the rapid development of the logistics market. Demand for high-level rail freight transport

The current railway freight transportation planning mainly faces the following problems: 1. There is a lack of theoretical research, and the existing theoretical methods are difficult to support the whole process of transportation organization

The current organizational model is freight demand-train formation plan-train operation diagram-online operation. In the train formation planning process, the planning only considers the station-to-station transportation process, and it is difficult to expand to both ends, which leads to the current planning mode. , Theories and methods are difficult to support the whole process of railway cargo transportation organization

2. The support for the cash rate of goods delivered to the deadline is poor

First, my country’s concept of train marshalling planning emphasizes the saving of train hours, and insufficient consideration is given to the time limit for delivery of goods; poor wire bonding
