specific Embodiment 1

[0111]Step 101: Obtain the addresses and construction costs of all logistics centers to be selected, as well as the addresses of distribution points. The logistics distribution center to be selected refers to the logistics distribution center that has not yet been constructed, the construction cost refers to the estimated cost of the logistics distribution center to be built, and the distribution point refers to the location where the logistics distribution center needs to deliver the goods.

[0112] Step 102: Randomly generate an initial population according to all logistics distribution centers and distribution points to be selected. The initial population P contains N individuals. According to the actual situation, generally more than 100 individuals should be selected, and N>100. Each individual indicates which logistics distribution center should be selected for each distribution point, and the selected logistics center is equivalent to being selected, which is finally ex...

Abstract

The invention discloses a multi-objective evolutionary logistics distribution center site selection optimization method and system. On the basis of a traditional single-target logistics distribution center site selection model, the distribution cost from a distribution center to a distribution site and the construction cost of the distribution center are optimized as two targets respectively, so that the cargo transportation cost and the construction cost of the selected distribution center address can be reduced to the maximum extent.

Description

technical field [0001] The present invention relates to the field of logistics center location selection, in particular to a multi-objective evolution logistics distribution center location optimization method and system. Background technique [0002] The logistics distribution center is a modern circulation equipment engaged in the allocation of goods and delivery to the distribution point, and is the central hub of the logistics system. In the analysis and design of the logistics system, the location of the logistics distribution center needs to be modeled and quantified. Reasonable selection of the location of the distribution center can reduce cargo transportation costs, reduce operating costs, and eliminate land price differences between different cities or different locations in the same city. The negative impact brought about by it will reduce the construction cost, promote the coordination and cooperation of the two flows of production and consumption, and ensure the...
