Multi-attribute decision-making method for emergency material storage siting based on triangular hesitant fuzzy numbers

Abstract

The invention provides a multi-attribute decision-making method based on triangular hesitant fuzzy numbers for emergency material storage, comprising: establishing an evaluation index system for emergency material storage; constructing a triangular hesitant fuzzy decision matrix for emergency material storage; The triangular hesitation fuzzy decision matrix is ​​expressed in the form of structural elements and transformed into a scoring function matrix; the weight of the evaluation index is determined by the maximum deviation method; the comprehensive score value of the site selection plan is calculated; address schemes. The invention expresses and operates the triangular hesitant fuzzy numbers based on the fuzzy structural element theory, constructs a scoring function based on the structural element theory to convert the triangular hesitant fuzzy numbers into real numbers, and effectively avoids the loss of information in the decision-making process. Based on the weight deviation theory, an optimization model with the goal of maximizing the deviation and the weight preference and the actual allowable floating range of the weight as constraints is established to calculate the index weight value, which is more in line with the actual decision-making process.

Description

technical field [0001] The invention relates to the technical field of site selection decision-making for an emergency material reserve storehouse, in particular to a multi-attribute decision-making method for site selection of an emergency material reserve storehouse based on triangular hesitant fuzzy numbers. Background technique [0002] In today's world, natural disasters, accidents, public health and social security emergencies occur from time to time. my country is also a country deeply affected by natural disasters. More than 70% of the cities and more than 50% of the population are distributed in meteorological disasters, earthquakes, etc. Areas severely affected by natural disasters such as disasters, geological disasters and marine disasters. After the occurrence of an emergency, it causes great casualties and economic losses, and has a huge impact on social stability and the physical and mental health of the masses. However, studying the theory of optimal site sel...

Problems solved by technology

[0003] At present, the multi-attribute fuzzy decision-making method on the site selection of emergency material reserve mainly uses the fuzzy number of single membership degree to represent the uncertainty in the decision-making process, but does not fully consider the situation of inconsistent opinions and too many fuzzy sources in the evaluation process of expert decision-making.
