Embodiment 1

[0048] The following introduces Embodiment 1 of a logistics transportation scheduling method with a time window provided by the present application, see figure 1 , embodiment one includes:

[0049] Step S101, obtaining a logistics transportation scheduling model with a time window;

[0050] In logistics and transportation scheduling, the above-mentioned logistics and transportation scheduling model with time window mainly refers to a model that describes multiple vehicles completing delivery tasks for multiple customer points within a preset time range. More specifically, the logistics transportation scheduling model with time windows can be described as: there are multiple vehicles in a depot, and they deliver goods to several customer points within a specified time period (time window). In some cases, certain penalties will be given. Each vehicle departs from the yard and returns to the original yard after passing through all the customer points that the vehicle is respons...

Embodiment 2

[0058] see figure 2 , embodiment two specifically includes:

[0059] S201. Obtain a logistics transportation scheduling model with a time window;

[0060] The above logistics and transportation scheduling model with time window is as follows:

[0061]

[0062] Among them, K (unit: vehicle) represents the total number of transport vehicles, N (unit: number) represents the number of customer points, d ij (i, j=0,1,...,N, unit: kilometer) indicates the straight-line distance of the transport vehicle from customer point i to customer point j, E i Indicates the earliest arrival time of goods requested by customer point i, L i Indicates the latest arrival time of goods requested by customer point i, C 1 (unit: yuan / minute) indicates the penalty coefficient for early arrival, C 2 (unit: yuan / minute) indicates the penalty coefficient for being late, t ik Indicates the actual time when vehicle k arrives at customer point i, r ijk (i, j=0,1,...,N, k=1,2,...,K) is a variable t...

Abstract

This application discloses a logistics transportation scheduling method, device, equipment and readable storage medium with a time window, and provides a search scheme for a logistics transportation scheduling model with a time window, aiming at the logistics transportation scheduling with a time window model, the scheme uses the harmony search algorithm optimized based on the electromagnetic-like mechanism algorithm to search for the optimal path, and measures the travel length and timeout degree of the delivery path corresponding to each harmony according to the target fitness function of the model, and finally determines the target optimal path. Excellent harmony, as the logistics transportation scheduling result of the logistics transportation scheduling model with time window. It can be seen that this solution significantly improves the search efficiency of the logistics transportation scheduling process, and meets the customer's requirements for delivery time while ensuring a short path length.

Description

technical field [0001] The present application relates to the field of transportation scheduling, in particular to a logistics transportation scheduling method, device, equipment and readable storage medium with a time window. Background technique [0002] Logistics is the process of organically combining functions such as transportation, storage, loading and unloading, packaging, circulation processing, distribution, and information processing according to actual needs during the physical flow of goods from the supply point to the receiving point to achieve user requirements. [0003] As a part of demand supply chain activities, logistics transportation needs to ensure that customers' needs for goods, services and related information are met on the one hand, and on the other hand, it needs to improve transportation efficiency and reduce transportation costs. Therefore, reasonable planning and control of the transportation process from the supply point to the receiving point...
