Problems solved by technology

But on the whole, the current emergency material reserves at all levels generally have the problems of small warehouse area, low construction standards, and serious shortage of basic equipment, which cannot well meet the needs of the current disaster relief work, let alone adapt to the party and the state's preparedness in the new era. New requirements for disaster relief work

Embodiment Construction

[0035] The multi-facility fair location selection method proposed by the present invention is described in detail as follows in conjunction with the accompanying drawings and embodiments.

[0036] The multi-facility fair site selection method of the present invention is based on national and regional emergency material reserves at all levels, analyzes the regional demand for facilities under major emergencies and the coverage of emergency material reserves at each level, and calculates the distance between each point. Distance, selected facility. The location selection method includes the setting of demand points, facility points and coverage radius. Among them: demand points are the elements that need emergency materials and services in the region, which can represent people, communities or villages; facility points are the layout of emergency material reserves at all levels, and they are abstracted as "point" elements in the present invention; coverage radius is Refers to t...

Abstract

The invention relates to a multi-facility fair site selecting method. The method comprises the following steps of: calculating a shortest distance from all demand points to facility points and constructing a distance matrix; calculating a weighted average distance from each selectable facility point to all the demand points according to the distance matrix; constructing a matrix of a weighted distance variance between all the facility points and the demand points; constructing a fair site selecting target function according to a site selecting principle of selecting the facility point with the smallest weighted distance variance; solving the target function and finishing multi-facility fair site selection. The method and a system simplify the solving difficulty of the fair problem of multi-facility site selection, select by adopting an ant colony algorithm, more approach a practical value and are suitable for solving the site selecting problem of public service facilities in all hierarchies.

Description

technical field [0001] The invention relates to the technical field of location selection of public service facilities, in particular to a method and system for fair location selection of multiple facilities. Background technique [0002] Usually, after a major emergency occurs in a certain area, the local government mainly initiates the emergency plan, establishes an on-site headquarters, and unifies the command and dispatch of the emergency response work, including the emergency mobilization of various forces and resources, and the formation of an expert group to provide response and assistance. Decision-making services for dealing with emergencies, issuing emergency orders in a timely manner to mobilize relevant forces for reinforcements, etc. Due to the lack of coordination mechanism for emergency response among various government departments, and the lack of awareness of emergency prevention in the public sector, the existing allocation of emergency resources and the lo...
