Problems solved by technology

Nowadays, many logistics and distribution companies only consider one aspect in the distribution process. However, the problems of cargo loading and route planning are closely related and mutually restrictive. If only one aspect is considered alone, it cannot be optimized to the maximum extent. Logistics distribution, so in order to really improve the efficiency and benefits of the distribution link, it is necessary to combine the key transaction nodes of the distribution link, fully consider and study the connection between the transaction nodes, and conduct a unified solution

Embodiment Construction

[0056] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, but not to be construed as a limitation of the present invention.

[0057] The analysis method of an improved dynamic analysis model for regional vehicle path planning proposed in this embodiment divides the distribution and transportation problem into three main processes by modularizing and disassembling: the selection of distribution transit centers, the problem of cargo loading, and the Distribution routing problem. The three problems are solved separately by sharing unified order data. Finally, a transportation cost model is established based on the uni...

Abstract

The invention discloses an improved analysis method of a regional vehicle path planning dynamic analysis model, which comprises the following steps of: selecting a distribution transfer center according to the existing order quantity, dividing goods according to regions, concentrating the goods to the corresponding distribution transfer center, and then performing centralized planning on the goods of the transfer center to obtain a regional vehicle path planning dynamic analysis model. And establishing a cargo stowage model by using the 3L-CVRP combinatorial optimization model. And in the third stage, road strength planning is carried out on the trucks which have been successfully allocated, due to the fact that a colistia path optimization algorithm based on the two factors of the time window and the material cost is provided, the problem of local optimization caused by a traditional heuristic algorithm is avoided, and the transportation efficiency of goods distribution of the logistics center is effectively improved.

Description

technical field [0001] The invention relates to an analysis method for an improved dynamic analysis model of regional vehicle path planning, and belongs to the technical field of vehicle transportation scheduling optimization. Background technique [0002] In modern enterprises, with the advent of the era of intelligence and mechanization, modern logistics includes advanced organizational management methods, intelligent science and technology, and diversified information methods, which undoubtedly open up new sources of profits for enterprises. [0003] In many logistics production activities, distribution is at the core and plays a vital role in the logistics system. Distribution is the terminal link of logistics, which realizes the final allocation of resources and is an important link in modern logistics. Since the delivery destination of the goods is certain, a reasonable assembly sequence of vehicles and goods can not only effectively improve the space utilization rate...
