| In recent years,emergencies in the waters along the "Marine Silk Road" frequently occur,which not only cause huge economic losses,casualties,but also cause great damage to the environment.In order to effectively respond to these emergencies,this paper studies the location of the Maritime Silk Road emergency reserve warehouse,and establishes an emergency reserve warehouse network covering the waters along the route,so as to provide timely rescue for the ships in distress.First,the risk points of the water area are determined.Considering that the coverage location model constructed in this paper is the comprehensive coverage of the general risk points and multiple coverage of important risk points by the emergency reserve,it is the subsequent location work to accurately determine the risk points of the water areas along the line The basics.In this paper,through the spatial analysis function of ARCGIS,the risk assessment of the waters along the route is carried out to determine the general risk points and important risk points.Secondly,in terms of model construction,this paper establishes a coverage site selection model,which considers the cargo damage rate and material allocation,and aims to minimize the total cost of construction of emergency reserves,transportation costs,and storage costs of rescue materials.Comprehensive coverage of risk points and multiple coverage of key risk points.And design genetic algorithm to solve the model.Then in the analysis of calculation examples,this paper selects the ports along the Maritime Silk Road as candidates for the emergency reserve.Combining the risk points determined in Chapter 3,the location of the Maritime Silk Road emergency reserve is determined through the coverage selection model and genetic algorithm.Location and corresponding reserves.Finally,the main conclusion of this paper is obtained:after determining the risk point and risk level through the spatial analysis function of ARCGIS,taking the minimum total cost as the goal,considering the cargo damage rate,establishing a multiple coverage location model,and designing a genetic algorithm for the model,and finally through the design The calculation and analysis of the calculation example found that the layout of the storage reservoirs distributed in the waters along the Maritime Silk Road was more reasonable,realizing comprehensive coverage of the waters along the line and multiple coverage of key waters.To a certain extent,the validity of this site selection idea proposed in this paper is verified,and it can provide a decision basis for the site selection of the marine silk emergency reserve.At the same time,it also expands the application scenarios of ARCGIS and enriches the emergency location system. |
