[0126] Taking the positions of the two relief supplies suppliers as the diagonal line to delineate the monitoring range of the disaster area as an example, the disaster intensity coloring map is obtained according to formula (4). Among them, the cluster analysis obtained the urgency changes and the evolution of the 16 divided regions after receiving the disaster warning at t=1, t=2 and t=3 respectively, as shown in the attached Figure 2-4 shown. At the beginning of the flood disaster, t=1 and t=2 are in a short stable period, and the blue area expands rapidly at t=3. The main reason is that the severity of the flood di...

Abstract

The invention discloses a flood disaster emergency material distribution analysis method, and relates to a network analysis method. The method comprises the following steps of: carrying out real-timedemand point estimation on disaster area material demands by utilizing initial data obtained by an execution layer of an emergency relief distribution center; carrying out unsupervised cluster analysis according to five flood disaster area-related attributes such as a relief frequency, a casualty rate, a vulnerable group rate, a rainfall capacity and a building damage degree, so as to obtain divided disaster areas; determining emergency degree priorities of material distribution areas; distributing residual relief materials in an emergency inventory to the disaster areas according to weight sequences; updating the disaster area material demands in real time until the disaster area demands achieve a preset satisfaction degree; and realizing dynamic interaction between a decision making layer and the execution layer. According to the method, the emergency material deployment problems of flood disaster areas are solved, and golden relief periods are effectively utilized to complete humanitarian relief.

Description

technical field [0001] The invention relates to a network analysis method, in particular to a flood disaster emergency material distribution analysis method. Background technique [0002] Among all types of disasters that occurred between 2008 and 2017, floods accounted for 38.4% of the disaster statistics, causing economic losses to increase by 51%. Research on emergency logistics in flood-stricken areas is increasingly emerging. In recent years, research on disaster emergency logistics has mainly focused on the optimization of supply networks with time and efficiency goals as the main objectives. More emphasis is placed on the time and cost optimization of emergency distribution, ignoring the satisfaction of the needs of the people in the disaster area. In addition, there is no research on the distribution of emergency materials combined with "Internet +". Contents of the invention [0003] The purpose of the present invention is to provide an analysis method for the d...
