Problems solved by technology

The current research on multi-model vehicle planning is mostly based on a single model, and the vehicle planning is prioritized based on the loading rate, while the vehicle planning based on the loading rate only includes the constraints of the vehicle loading rate, and does not consider the partition distribution and vehicle transportation distance. Concentrate on the selection of small models, resulting in an increase in overall logistics and transportation costs

Embodiment Construction

[0079] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0080] S1: Analyze the elements of logistics and transportation planning, and build a multi-vehicle logistics and transportation model.

[0081] In the S1 step, the logistics transportation area in the logistics transportation planning elements is analyzed, including:

[0082] The logistics transportation area is divided into the warehouse logistics transportation area and the cargo logistics transportation area, wherein the warehouse logistics transportation area is the transportation area between the logistics distribution center and the warehouse, and the cargo logistics transportation area is the transportation area between the logistics distribution center and the distribution target;

[0083] In a specific embodiment of the present invention, each city has 3 warehouses and 1 logistics distribution center, and th...

Abstract

The invention relates to the technical field of logistics transportation planning, and discloses a multi-vehicle-type logistics transportation planning method, which comprises the steps of analyzing logistics transportation planning elements, and constructing a multi-vehicle-type logistics transportation model; determining a logistics planning objective function and constraint conditions according to the multi-vehicle type logistics transportation model; performing optimization solution on the logistics planning objective function by using a conjugate gradient algorithm to determine an optimal solution; and taking the optimal solution obtained by solving as a logistics transportation strategy of multiple vehicle types. According to the method, the multi-vehicle-type logistics transportation model is constructed based on the logistics transportation cost, the transportation distance and the average loading rate of the vehicles, the target function of the model is optimized and solved by using the conjugate gradient algorithm, and the optimal solution obtained by solving is used as the multi-vehicle-type logistics transportation planning strategy. The finally realized logistics transportation planning strategy ensures that the logistics transportation cost is minimum, the transportation distance is shortest and the average loading rate of vehicles is highest.

Description

technical field [0001] The invention relates to the technical field of logistics transportation planning, in particular to a multi-vehicle logistics transportation planning method. Background technique [0002] The model vehicle planning problem refers to how to choose the vehicle combination of each model when delivering goods from the warehouse point to each cargo demand point. The current research on multi-model vehicle planning is mostly based on a single model, and the vehicle planning is prioritized based on the loading rate, while the vehicle planning based on the loading rate only includes the constraints of the vehicle loading rate, and does not consider the partition distribution and vehicle transportation distance. Concentrating on the selection of small models will lead to an increase in the overall logistics and transportation costs. [0003] In view of this, the present invention proposes a multi-vehicle logistics transportation planning method, constructs a m...
