| 摘 要： | 基于模糊数学、排队理论与选址理论，建立了应急救援物流中物资分发点的多目标模糊排队选址优化模型，其中：受灾点的需求率和物资分发点的服务率为模糊数，物资分发点建立成本最小和救援反应时间最短为目标函数．设计了模型的求解算法，确定了物资分发点的选址以及各个分发点所覆盖的受灾点区域范围．结合具体算例，验证了模型的实用性，并分析了物资分发点应急服务能力对救援效果的影响．

| Abstract: | Based on fuzzy mathematics,queuing theory and location theory,a model is introduced into solving the problems about item distribution spots location optimization in emergency relief logistics where the demand rates of disaster spots and service rates of item distribution spots are fuzzy numbers.The proposed model aims at jointly minimizing the setup costs for item distribution spots and relief response time.The algorithms are presented to set the proposed model to determine the location and covering scope o... |
