An Improved Heuristics about Layout of Emergency Station in a City

Abstract

In order to deal with the urgent public security incidents timely, to meet the requirements of the shortest emergency time, to consume the least emergency resources and rescue points, its necessary to achieve a compromised site selection scheme that reflects a decision makers preference on time and cost, in the decision about a citys layout of fire station is to probe into the site selection of safe emergency station under the emergency restrictions. This research used an improved heuristics to explore the solving of combination model about multi-rescue points under the limitation of time and resource, provided the emergency restrictions and a cost model about establishment of the safety emergency facilities, and proved the correctness of the model solution method theoretically. In a limited emergency time, this paper analyzed and obtained selection method on emergency service facility points. Through a numerical example illustrated that specific application of the calculation method, this method is suitable for the planning and construction of the public facilities, such as fire control, hospital first-aid stations.
