增建与公平情景下城市应急物资储备库网络优化模型

Network Optimization Model of Urban Emergency Material Reserve under the Scenario of Expansion and Equity

增建应急物资储备库以健全城市应急物资保障体系,实现城市应急物资储备库网络优化的同时保持“空间正义”对于城市应急物资保障能力提升极为重要。该文以科学增建城市应急物资储备库和公平调度应急物资为目标,构建了基于加权距离方差最小准则的公平设施选址模型,设计了拉格朗日松弛启发式算法求解模型,选取石家庄市为例实证了模型的有效性。

As far as the improvement of the urban emergency material support capacity is concerned,it is extremely important for building additional emergency material reserves to improve their emergency material support system and for realizing the optimization of the urban emergency material reserves network while maintaining“spatial justice”.This study aims at the scientific construction of urban emergency materials reserve network and the fair dispatch of emergency material to formulate the optimization model of urban emergency materials reserve network considering the expansion construction and fair situation.The Lagrange relaxation algorithm is used to solve the model,and an empirical study is carried out by taking Shijiazhuang City of Hebei Province as an example.
