US 2024/0177258 A1 · METHOD AND DEVICE FOR FOOD SECURITY INDEX EVALUATION

Abstract

The present disclosure provides a method and device for food security index evaluation. The method includes the following steps: dividing a food security status into two dimensions and formulating a plurality of first-level indicators and second-level indicators for the two dimensions, respectively; establishing a hierarchical structure model with the plurality of first-level indicators and second-level indicators of the two dimensions by an analytic hierarchy process (AHP); obtaining indexes of the two dimensions; and calculating a food security index FI, where a result is determined as: 0<FI<1; when FI is closer to 1, the food security status is better; and when FI is closer to 0, the food security status is worse. The present disclosure adopts a combined subjective and objective evaluation method, and therefore an evaluation result is more accurate and objective.

A method for food security index evaluation, comprising the following steps:

S1, dividing a food security status into two dimensions:
food production and consumption security status A1 and food quality security status A2, and formulating a plurality of first-level indicators and second-level indicators for the two dimensions, respectively;
S2, establishing a hierarchical structure model with the plurality of first-level indicators and second-level indicators of the two dimensions by an analytic hierarchy process (AHP);
S3, obtaining an index FI (A1) of the food production and consumption security status A1 and an index FI (A2) of the food quality security status A2;
and
S4, calculating a food security index FI according to the FI (A1) and the FI (A2), wherein a result is determined as:
0<FI<1;
when FI is closer to 1, the food security status is better;
and when FI is closer to 0, the food security status is worse.
