Automatic site selection method and device for large-scale emergency facilities and readable storage medium

Abstract

The invention discloses an automatic site selection method and device for large-scale emergency facilities and a computer readable storage medium. The method comprises the following steps: based on urban road network data of a to-be-planned area, calculating the shortest passing path among all road network nodes in the to-be-planned area; encoding the shortest path and a pre-constructed facility site selection model, wherein the facility site selection model indicates that emergency facilities set based on an emergency facility layout rule need to meet site selection conditions in the site selection process; and based on the coded shortest path, calculating the optimal solution of the facility site selection model by using a genetic algorithm to obtain the set total number and the set position information of the emergency facilities to be subjected to site selection in the to-be-planned area, and taking the set total number and the set position information as the site selection information of the emergency facilities for automatic output. On the premise that the setting number of the emergency facilities does not need to be determined in advance, site selection can be conducted onthe emergency facilities which need to balance the contradiction between the safety and economy of the facilities and are large in scale, and the layout of the urban emergency facilities is optimized.

Description

technical field [0001] The present application relates to the field of facility location technology, in particular to a method, device and computer-readable storage medium for automatic location selection of large-scale emergency facilities. Background technique [0002] It is understandable that the site selection of emergency facilities has a great impact on the safety of the entire city. With the gradual increase in the scale of urban construction, in order to effectively solve the problems of high construction costs and waste of space resources for urban emergency facilities, more For emergency services, the traditional manual site selection of emergency facilities based on the layout of urban buildings obviously cannot meet the actual needs. [0003] In the process of site selection for emergency facilities, such as site selection for fire stations, first aid stations, logistics centers, and nuclear power plants, layout safety and construction costs are two irreconcilab...

AI Technical Summary

Problems solved by technology

Existing accurate algorithms, such as branch and bound algorithm, center of gravity method, etc., are only suitable for solving small-scale facility location problems, and are not suitable for large-scale location problems such as urban fire station location
