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 rough positioning-oriented cooperative vehicle path optimization method. According to the customer's rough positioning information provided by a logistics service provider to its partners, a cooperative vehicle path model oriented to rough positioning is constructed, and LNS and local search algorithms are used The combined improved ant colony optimization algorithm solves the cooperative vehicle routing problem for rough positioning. Through the technical solution of the invention, logistics service providers form a horizontal logistics alliance, optimize the entire logistics distribution network, and greatly reduce transportation costs. Compared with other prior art, the present invention can more effectively solve the problem of cooperative vehicle routing 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...
