针对存在传染效应突发事件的资源布局问题研究

Study on Resource Location/Allocation Problem of Emergencies with Infection

本文针对一类具有传染效应的突发事件建立资源布局模型。具有传染效应的突发事件是指在某地区发生事件,在其周围一定距离内的其他地区也会发生同类事件。对初始发生事件供应不同的资源将影响到其他地区的资源需求,因此整个地区的资源需求表现为多个需求组合。本文建立的模型考虑到某个地点发生事件带来的多种资源需求组合,将问题分为两个阶段进行分析,并同时考虑选址和资源配置来满足该地区发生事件需求以及引发的其他地区的资源需求。针对此模型,构造两层的禁忌搜索算法,并在最后给出算例。

This paper develops a model of location and allocation in view of emergency with infection. Infection means when an emergency occurs in one place, the same emergency may occur in the places near it. The resource supply for the place where the emergency happens will influence the resource demand of the emergency elicited. So the demand of the whole place is combinations of demand. The model in this paper considers demand combinations and analyzes the problem in two stages and combines location and allocation in one model. Finally, this paper designs a two--layer tabu search algorithm and gives a numerical example.
