Problems solved by technology

Second, resource sharing may affect the strategy of logistics service providers, but previous research models on the collaborative vehicle routing problem all assume that horizontal logistics alliances can control all resources of each logistics service provider
At this time, since most of the logistics resources of the logistics service provider will be occupied by the horizontal logistics alliance for a long time, the long-term decision-making of the logistics service provider will be limited to a certain extent

Abstract

The invention discloses a collaborative vehicle path optimization method for rough positioning. The method includes: according to the rough positioning information of the customer provided to the partner by the logistics service provider, constructing a collaborative vehicle path model oriented to rough positioning, and solving the collaborative vehicle path problem oriented to rough positioning by applying an improved ant colony optimization algorithm combining an LNS and a local search algorithm. According to the technical scheme, the logistics service provider forms a transverse logistics alliance, the whole logistics distribution network is optimized, and the transportation cost is greatly reduced. Compared with other technologies, the method can more effectively solve the cooperativevehicle path problem oriented to rough positioning, and can obtain a better solution.

Description

technical field [0001] The invention belongs to the technical field of cooperative vehicle route optimization, in particular to a method for cooperative vehicle route optimization oriented to rough positioning. Background technique [0002] Logistics horizontal cooperation refers to the unified management of logistics resources by multiple logistics service providers in order to reduce the cost of logistics activities. Cooperative vehicle routing problem is one of the main research contents of logistics horizontal cooperation. In recent years, factors such as fierce competition in the global market, rising transportation costs, shortened product life cycles, and increased customer expectations have brought enormous pressure to logistics service providers (LSPs). In this case, the cooperation among logistics service providers is increasing day by day in order to reduce the cost of logistics distribution, improve resource utilization and enhance market competitiveness. If th...
