Abstract

The embodiment of the invention discloses a logistics distribution line generation method and device, and the method comprises the steps: carrying out mesh generation of distribution points accordingto geographic positions of distribution points in order data, and determining a local search neighborhood based on meshes; carrying out split clustering on the distribution points in the local searchneighborhood to obtain an initial cluster; and iteratively searching the distribution points in the local search neighborhood by taking the initial cluster as a search starting point, and generating adistribution route comprising the distribution points according to a preset constraint condition. According to the technical scheme of the embodiment, the high-dimensional spatial data is discretizedthrough the grids, so that the scale of the wiring planning problem is effectively reduced, and the operation speed is increased.

Description

[0001] technology neighborhood [0002] The present application relates to the field of computer technology, in particular to a method and device for generating a logistics delivery route. Background technique [0003] In the field of logistics distribution, for large-scale customer orders, how to reasonably allocate transportation vehicles, plan distribution routes, and effectively reduce transportation costs is an important issue that enterprises care about. The logistics distribution route planning problem is described as: there are several distribution centers and customer nodes, and now it is necessary to start from the distribution center and use several vehicles to provide services (delivery / pickup) to several customer nodes within a certain area, and it is required to plan vehicles reasonably The driving route is to minimize the vehicle driving cost while ensuring the completion of the delivery task, and at the same time meet the vehicle capacity (or loading rate) cons...
