摘要:
为解决城市应急医疗集配中心配送时间长及配送覆盖范围小的问题,提出构建城市应急医疗物资集配中心第2代非支配排序遗传算法优化选址模型.该方法以最小化总体运输成本和最大化应急物资集配中心对邻近地区的人口数量和医疗资源覆盖为目标,建立改进的层次分析法-模糊折衷决策评价模型,引入折衷模糊决策方法进行总体选址方案决策优选.以中国石家庄市藁城区应急医疗物资集配中心选址为例,验证该模型的可行性.结果表明,建设7个集配中心即可满足石家庄市藁城区的疫情防控需求,进一步节约建设和运输成本,最优方案中平均运输车程耗时为18.9 min,30 min以上车程占比为13.3%,相较于优选前各方案的平均值分别下降了49.1%和80.0%.研究成果可为城市突发公共卫生事件下应急集配中心选址方案提供参考依据.
Abstract:
In order to solve the problems of long distribution time and small distribution coverage of urban emergency medical materials distribution centers, this paper constructs an nondominated sorting genetic algorithm-Ⅱ-based (NSGA-Ⅱ-based) optimal location model for the urban emergency medical material distribution center. Aiming at minimizing the cost of transportation and maximizing the coverage of the population and medical resources of the emergency material collection and distribution center to the adjacent areas, the model introduces a compromise fuzzy decision-making method for the overall location plan and establishes an improved analytic hierarchy process (AHP)-fuzzy compromise decision evaluation model. The compromise fuzzy decision-making method is constructed to optimize the overall site selection decision-making. The feasibility of the model is verified by taking the location selection scheme of emergency medical materials collection and distribution in Gaocheng District of Shijiazhuang City, Hebei Province as an example. The results show that the construction of seven centralized distribution centers can meet the needs of epidemic prevention and control in Gaocheng District, Shijiazhuang City. The construction and transportation costs are reduced. The average transportation time of the optimal scheme is 18.9 minutes and the proportion of travel time over 30 minutes driving is 13.3%, which are reduced by 49.1% and 80.0% respectively compared with the previous scheme. The research results can provide reference for the location plan of emergency collection and distribution center under urban public health emergencies.
