Research on Optimizing the Location and Layout of National Emergency Material Reserve

Abstract

Scientific planning, and the layout of the national level reserve base of emergency materials, will help improve the effectiveness of a country’s overall emergency disaster reduction system. Based on the P-center location theory, this paper analyzes the factors affecting site selection at the national and state levels, determines the reasonable number of emergency material reserve bases at national and state levels, and then develops a national macro-level emergency supply reserve location planning model. In this study, the city of 28 states in a country were selected as alternative reserve cities and emergency demand city matrix, to conduct the research. The model is solved using a variable neighborhood search algorithm (VNS). The calculation results obtain the reasonable number of emergency material reserve bases set at the national level in this studied country, and the optimal solution of the base layout can be obtained if the number of emergency reserve bases set at the national level remains unchanged. The experimental results shows that the selected algorithm is reasonable.

Site Selection of Multi-Level Material Bases in Coal Mine Considering the Hierarchical Reserve Mode and Demand Difference—A Case Study

“…We obtained geographic information, risk value, and accident data of 30 coal mines from Liaoning Mining Safety Supervision Bureau in previous years, as show in Table 6. Since there are no documented historical records available for the demand for coal mine emergency materials and the use of specific materials during the accident rescue process, we referred to literature [46] and used the Python random generation program to simulate the demand for coal mine emergency materials. Due to the variety of coal mine rescue materials and equipment, and the parameters of various models of equipment are different, in order to facilitate the calculation, this paper use the volume as the specific quantity and unifies the price, as shown in Table 7.…”

Research on site selection of emergency material reserve based on set pair analysis and TOPSIS integration method: A case study of Hebei Province, China

“…One is the P-median model, P-center model, coverage location model, multi-objective programming model and the optimization model of the above models, and the intelligent algorithm is used to solve; The other is to transform the site selection problem into a multi-attribute decision making (MADM) problem by combining MADM and using TOPSIS [4], Analytic Hierarchy Process (AHP) [5] and other methods to evaluate and sort. For the former, the single-objective programming model [6,7] is studied based on the coverage problem. Among them, Wu et al [6] studied the site selection model of emergency material reserves at the national and state levels.…”

“…For the former, the single-objective programming model [6,7] is studied based on the coverage problem. Among them, Wu et al [6] studied the site selection model of emergency material reserves at the national and state levels. The P-center location theory is introduced, and the variable neighborhood search algorithm is used to determine the quantity of material storage in the coverage area, so as to obtain the global optimal solution.…”
