ABSTRACT

ABSTRACT: Optimal configuration of emergency response resources is critical for disaster mitigation and protection of public health and safety. In this paper, the problem of configuring disaster response resources among a set of candidate nodes (hubs) is formulated as the p-hub centre problem, in which the objective is to minimize the maximum travel time from hubs to demand nodes (non-hubs). In order to cope with the uncertainty about travel time that is involved in the model parameter, formulations based on two-stage stochastic programming are proposed. The applicability of the proposed methodologies to a large-scale area is demonstrated using the real data of Yunnan province in China.
