Embodiment Construction

[0059] The technical solution of the present invention will be further described in detail in conjunction with the accompanying drawings and embodiments.

[0060] figure 1 It shows a schematic flow diagram of the method for logistics distribution network planning in this embodiment, as figure 1 As shown, a logistics distribution network planning method provided in this embodiment includes:

[0061] S1, obtain the distance of the shortest path directly accessible between each demand point;

[0062] S2. Construct a connected graph with the demand points as nodes and directly reachable shortest paths between each demand point as edges.

[0063] In reality, due to the criss-crossing road traffic extending in all directions, there can be multiple paths between two points in an area, and the directly accessible path in this embodiment refers to any two demand points or distribution outlets The path between a demand point and a person will not pass through the path of other demand...

Abstract

The invention relates to the technical field of logistics distribution, particularly a method and a device for planning logistics distribution nodes. The method comprises the following steps: constructing a connected graph by taking demand points as nodes and a direct reachable shortest path between demand points as sides; dividing the connected graph into connected sub graphs as many as the distribution modes according to the business volume of each demand point; planning a distribution path according to each connected sub graph, and continuously updating and optimizing to obtain optimal positions of distribution nodes; calculating to obtain current operation profit; increasing the quality of the distribution nodes, repeating the steps until the operation profit gain is smaller than or equal to zero, outputting the quantity and the positions of the distribution nodes corresponding to the maximal operation profit. According to the technical scheme adopted by the invention, the distribution node planning strategy can be quantized, so that irrationality due to planning according to experience and intuition is avoided, the resources are further reasonably utilized and the distribution cost is reduced.

Description

technical field [0001] The invention relates to the technical field of logistics distribution, in particular to a logistics distribution network planning method and device. Background technique [0002] With the rapid development of e-commerce, express delivery and residents' sales, logistics distribution has formed a new industry with strong development momentum. The industry's income continues to increase rapidly, and the number of participating companies is increasing (including state-owned enterprises, private enterprises, and foreign companies), and the competition in terms of business scale, network coverage, and market share is becoming increasingly fierce. The logistics distribution system is a network system that distributes goods to consumers through distribution centers and networks at all levels. The distribution of distribution outlets at the end of distribution directly determines the coverage and service quality of distribution services. Distribution network...
