Distress among disaster-affected populations: delay in relief provision
研究了灾害后救援物资延迟提供导致的两种困境（临界性和贫困），并开发了一个混合整数目标规划模型来最小化这些困境，以伊斯坦布尔预期2030年发生的灾难性地震为例演示。
Central to humanitarian logistics is the minimization of distress among impacted populations in the aftermath of a disaster. In this paper, we characterize two levels of distress, termed criticality and destitution, with respect to the delay provision of relief items. Delay in provision of a relief item will lead to destitution for a tolerable number of days, beyond which it will lead to criticality. We develop a mixed-integer goal program that quantifies these two metrics with respect to the number of days without provision of each of a set of relief items. The model determines the allocation of resources and the distribution of available relief items in a manner that minimizes criticality and destitution in affected population segments. The use of the model is demonstrated for the aftermath of a catastrophic earthquake in Istanbul, expected to occur by 2030.
