应急物资筹集点动态保障能力评估研究

目的研究在应急物流资源动态使用情况下,应急物资筹集点的现存保障能力。方法在明确应急物资筹集点保障能力的含义、特征、影响因素的基础上,通过对应急物资筹集点保障能力构成要素及其相互关系的分析,构建了应急物资筹集点动态保障能力的表达模型,并通过算例进行了模型的有效性验证。结果应急物资筹集点可以根据已受领任务,以及在待领任务时间区间内各类资源的综合占用情况,动态地评测出在任一时间点的现存保障能力。结论该方法适用于某一筹集点在持续承担救援保障任务情况下的任务安排,使决策者对于应急物资筹集点的选定及筹集量的确定等应急物资筹集决策更加合理、可行。

Evaluation of Dynamic Support Capability of Emergency Materials Raising Point

The aim of this work was to study the existing support capability of an emergency material collection point under conditions of dynamic usage of emergency material resource. The definition, characteristics and influencing factors of support capability of emergency material collection point were clarified firstly, and then an expression model of dynamic support capability was established through the analysis on the support capability components and their interaction. And the effectiveness of the model was verified through a simulation instance. The existing support capability at any future timing of an emergency material collection point tasked could be evaluated well by the model based on the comprehensive occupation of various resources in the time ranges. The model is suitable for tasking for any emergency material collection point which is under conditions of sustained undertaking support task, and could increase the reasonability and feasibility of the decisions made for the selection of emergency material collection point and the collection amount.
