Abstract

The invention relates to a hub-and-spoke logistics network junction station site selection and distribution method based on a probability tabu algorithm. The method comprises the following steps that: firstly, adopting a random greedy strategy to construct an initial junction station site selection and distribution scheme; from the initial scheme, searching a neighbourhood based on junction station and non junction station exchange to determine an optimal junction station site selection; and in an exchange neighbourhood search process, in order to avoid repeated search, adopting a probability tabu search strategy to make an effective improvement on a traditional tabu object and a traditional ban lifting mechanism. On the basis of a situation that the junction station site selection is determined, the neighbourhood based on non junction station movement is subjected to deep search, and optimal junction station distribution is determined. By use of the method, an optimal junction station site selection and distribution scheme in a large-scale hub-and-spoke logistics network is determined in acceptable time, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of hub-and-spoke logistics network optimization, in particular to a hub-and-spoke logistics network site selection and distribution method based on a probabilistic taboo algorithm. Background technique [0002] With the rapid development of social economy, logistics is inseparable from people's life, and the scale of logistics network is constantly expanding. The traditional logistics network adopts a fully connected, station-to-station connection method, which not only wastes resources but also increases transportation costs. In contrast, the hub-and-spoke logistics network collects the goods flow from the source site to the hub station first, then transports them centrally between the hub stations, and finally distributes them to the destination site. Relying on economies of scale, the transportation cost is reduced, and resources are integrated at the same time to improve logistics efficiency. The utilization rate...
