A kind of express vehicle transportation scheduling method, system and equipment

Abstract

The method, system and equipment for dispatching express vehicle transportation proposed by the present invention achieve the purpose of reducing the transportation cost by effectively reducing the number of actually used vehicles and reducing the transportation distance through unified vehicle dispatching. First, obtain the set of transshipment centers in the region, and construct a vehicle transportation network diagram; then obtain the relevant information of the enterprise transshipment center, the inbound and outbound express and network vehicles, and analyze the main information of express and transportation vehicles; on the basis of the above, establish a shared network of vehicles The scheduling model is optimized, and the optimization objectives and constraints are determined; finally, a two-stage algorithm is used for vehicle scheduling. The invention can optimize the scheduling of vehicles at the shared network to the transshipment centers of express enterprises, and formulate a unified vehicle transportation scheme for the inbound and outbound tasks of each transshipment center.

Description

technical field [0001] The invention relates to the technical field of intelligent logistics, and more particularly to a method, system and device for dispatching express vehicle transportation. Background technique [0002] In the express city distribution, each express company has built its own transshipment center within the city. The express parcel first arrives at the city transshipment center for sorting. After sorting, the affiliated franchised outlets go to the center to pick up the goods and express them from the center. Distributed to the customers at the end of the franchise network. During the pickup process, it is usually accompanied by the pending shipment from the previous day to the center. According to the existing main transport mode of the transport order, after the implementation of the joint distribution and integration, the franchised outlets are integrated into the shared outlets, and the volume of inbound parcels has doubled. Depending on the size o...

Problems solved by technology

The research on the existing model mainly considers the continuous splitting or arbitrary splitting of the demand according to the unit. This assumption has certain limitations. In actual transportation, the customer’s demand often cannot be split into units, and it cannot be applied to the weight of the logistics express package. in different actual scenarios

At the same time, there are few relevant studies considering the time window, and most of the application scenarios are small-scale simulation examples or simulation cases, which have a large gap with practical applications.
