Problems solved by technology

[0004]Existing studies have shown that: assuming that the demand in the disaster-stricken area is small, only one emergency logistics center is required to be responsible for the distribution, and most of them are carried out in the form of touring distribution. However, in In the actual rescue process, the demand of the disaster-affected point may be large, and the temporal and spatial distribution of the supply of different materials is usually uneven; moreover, there are few studies on emergency logistics that consider the dynamic changes of

Abstract

The invention discloses a positioning-path planning method for emergency logistics. According to the method, emergency logistics center information, disaster point information, road information between an emergency logistics center and a disaster point and the like are comprehensively considered, and a Pareto optimal solution is obtained by utilizing a flower pollination algorithm, so that an optimal solution is provided for solving the positioning-path problem of emergency logistics.

Description

Technical field [0001] The present invention relates to the technical field of logistics distribution, in particular to a positioning-path planning method for emergency logistics. Background technique [0002] my country is a country seriously affected by natural disasters, and with the rapid economic development, the losses caused by disasters are gradually increasing. In order to minimize casualties and property losses, it is necessary to provide emergency protection for the needs of materials, personnel, and funds during the emergency rescue period, which has given birth to emergency logistics needs. [0003] Emergency logistics has the characteristics of suddenness, weak economy, timeliness, etc. In most cases, its logistics benefits are realized through logistics efficiency. This requires emergency logistics systems to meet the disaster-stricken points as far as possible under limited time, space and resource constraints. demand. Therefore, the key issue of emergency logisti...
