Abstract

The invention relates to the technical field of grain safety emergency and discloses a grain safety frangibility analysis method and system. The grain safety frangibility analysis method includes thefollowing steps: based on a grain data index of each region, adopting a factor analytical method to establish a safety frangibility evaluation model of grain supply, wherein the safety frangibility evaluation model includes a new index used for replacing the grain data index to show the grain level of each region; and calculating the grain level data of different regions under the safety frangibility evaluation model based on the new index, and performing cluster analysis on each region based on the grain level data, and determining the cover scope of grain emergency storage according to the cluster analysis. The factor analytical method and cluster analysis method are adopted, the safety frangibility evaluation model of grain supply of each region is established, and the cover scope of grain emergency storage can be reasonably determined.

Description

technical field [0001] The invention relates to the technical field of food security emergency response, in particular to a method and system for analyzing food security vulnerability. Background technique [0002] The food emergency reserve guarantee system is a major issue related to the national economy, the people's livelihood and national security. Especially in the event of an emergency, timely guarantee of food supply is the basic guarantee for resisting disasters and stabilizing society. However, in various emergencies at home and abroad recently, many unnecessary losses have been caused due to the lack of a scientific and efficient food emergency reserve guarantee system. [0003] At present, the defects of the grain emergency reserve support system are mainly manifested in the following aspects: 1) Due to problems such as unreasonable layout of grain emergency reserves in many areas, untimely command and dispatch, and inadequate logistics distribution, etc., the lo...
