BACKGROUND
At present, the logistics distribution industry has developed from the previous single vehicle point-to-point distribution mode to a logistics distribution mode of multi-vehicle to multiple collector-distributor points, that is, multiple distribution vehicles complete all distribution tasks together.
However, the existing path optimization methods are generally more helpful to solve the optimization of point-to-point and single vehicle to multi-point, such as route planning from point A to point B, and optimal path for point A to pass through multiple points. For the distribution of multi-vehicle and multi-task, the optimal method should be to automatically distribute all distribution tasks to multiple vehicles to complete in parallel, and change the distribution task for the single vehicle to the distribution task for the single vehicle to the collector-distributor point which is closest to multiple distribution points, and then make a further distribution. Obviously, using the previous distribution route planning method may only be applied to one vehicle to complete all distribution tasks, or manually divide these distribution points, and then perform route planning for multiple vehicles, which obviously cannot effectively improve the efficiency and reduce distribution costs.
Therefore, those skilled in the art provide a logistics distribution path optimization method based on multi-vehicle and multi-task to solve the problems raised in the above background art.
