Embodiment 1

[0073] The technical solution adopted in this embodiment is a post-earthquake hierarchical medical emergency facility site selection model, which complies with the following assumptions:

[0074] a) The demand points of post-earthquake medical emergency facilities are known, that is, they are set at the administrative center of the research area (usually representing the most concentrated point of population), so as to define the structural location and characteristics of the demand points.

[0075] b) The distance from the candidate medical emergency facility to the demand point is the straight-line distance from the facility to the center of the demand point;

[0076] c) Taking into account the severe road damage after the strong earthquake and the need for emergency rescue, helicopter transportation is used for medical emergency rescue after the earthquake;

[0077] d) The construction cost of all medical emergency facilities is the same.

[0078] The flow of this embodime...

Abstract

The invention discloses a site selection method for post-earthquake medical emergency facilities. The method comprises steps that (1), candidate points for the post-earthquake medical emergency facilities are determined; (2), influencing factors for site selection optimization of the post-earthquake medical emergency facilities are analyzed according to the specific conditions of a region; (3), weights of the various influencing factors are calculated through utilizing TOPSIS; (4), fairness, high efficiency, the maximum coverage range and appropriate cost consideration are taken as targets toestablish a base-level emergency medical facility site selection model; (5), a post-earthquake advanced emergency medical command post site selection model is established based on the base-level emergency medical facility site selection model of the step (4); and (6), the model is solved by the nested genetic algorithm, and a base-level medical emergency facility point set and advanced emergency medical command posts are determined. The site selection method is advantaged in that the site selection method can quickly and scientifically determine the medical emergency facility points, and the method is of great significance to reduce casualties after earthquakes.

Description

technical field [0001] The invention belongs to the technical field of post-disaster emergency management, and in particular relates to a site selection method for post-earthquake medical emergency facilities. Background technique [0002] my country is located at the intersection of the circum-Pacific seismic belt and the Eurasian seismic belt. There are many earthquakes, large intensity, wide distribution and shallow focus. It is one of the countries most seriously affected by earthquake disasters in the world. According to statistics, in the 20th century, there were more than 650 earthquakes of magnitude 6 or above in China: 100 of them were 7 on the Richter scale, and 10 were of magnitude 8 or above. 36%, ranking first in the world. In fact, according to post-disaster rescue experience, there is a "golden 72 hours" after an earthquake. If timely and scientific rescue can be carried out during this period, the survival rate of the wounded will be greatly improved. Howev...
