近年来,随着经济的发展,农村公共危机形势严峻,文章以CNKI和Web of Science中有关农村公共危机文献作为数据来源,采用文献计量等分析法对文献进行系统梳理和回顾。随着时代的发展,该方面的研究呈现出不断变化和多学科交叉融合的整体发展趋势,已形成一定的研究热点。此研究对了解和分析国内外公共危机应急管理研究的发展动态、掌握国内目前此主题研究的发展态势以及对后续学者的研究等提供有益参考价值。
In view of the pressure time of emergency rescue against the infectious diseases,a mathematical model to optimize the location of emergency rescue centers is proposed.The model takes full account of the spread function of infectious diseases,the cycle of pulse vaccination,the distance between the demand area and the emergency rescue centers,as well as the building and maintenance cost for the emergency rescue center,and so on.At the same time,the model integrates the traditional location selection models which are the biggest cover model,the p-center model and the p-median model,and it embodies the principles of fairness and efficiency for the emergency center location.Finally,a computation of an example arising from practice provides satisfactory results.
