摘要
针对中国农村地区可持续医疗中心的选址与分配问题,提出了一种基于多目标整数规划模型的决策方法。首先,通过分析可持续医疗中心选址过程中的影响因素,构建可持续发展影响因素指标体系,通过集结计算得出综合指标值。然后在此基础上建立选址与分配的多目标优化模型,并采用基于隶属度函数的加权和方法将多目标优化模型转化为线性规划模型,通过求解该模型,得出医疗中心选址与分配结果。最后,通过一个算例来证明所提方法的合理性和可行性。该方法可以比较直观的得出选址与分配的决策方案,为我国农村地区医疗中心选址问题提供重要的决策支持。
Aiming to location-allocation problem of the healthcare center,a decision making method based on multi-objective integer programming model is proposed in this paper.Firstly,the factors that influence the location process of sustainable healthcare center are analyzed,a Sustainability Factors Indicator System is constoucted,a comprehensive index value calculated by aggregation calculation is obtained.Then on such basis a location-allocation multi-objective optimization model is constructed.The method of weighted sums is used to change the multi-objective optimization model into linear programming model.By solving this model,the location-allocation results of sustainable healthcare center can be obtained.Finally,a case is given to illustrate the feasibility and practicality of the proposed method.This method can get a location-allocation decision scheme intuitively,so that it can provide decision support for location problem of sustainable healthcare center in rural areas of China.
