本文采用随机优化技术，在八个城市之间分配稀缺的国家资源，以最好地应对三个同时发生在这些地点的灾害。我们的第一个模型分析了在资源限制的情况下无法实现绩效目标的风险，而我们的第二个模型分析了满足目标绩效水平所需的资源。第三个混合模型（由前两个模型构成）分析不同财政预算的影响。通过查看位置重要性、同时发生的灾害数量和资源需求的不同设置，进行了额外的敏感性分析。我们反映了这些问题的建模技术的使用，并讨论了政治方面的资源分配，这些模型不能解决的影响。我们还反映了需要先进的建模，以认识到用户的能力和现实的假设，如果他们要影响灾害管理人员的做法的可用性。
This paper uses stochastic optimisation techniques to allocate scarce national resource across eight cities to best respond to three simultaneous disasters happening across these locations. Our first model analyses the risk of not being able to achieve performance targets given resource constraints while our second model analyses the resources needed to meet target performance levels. A third hybrid model (constructed from the first two models) analyses the implications of different financial budgets. Additional sensitivity analysis is performed by looking into different settings of location importance, number of simultaneous disasters, and resource requirements. We reflect on the use of such modelling techniques for these problems and discuss the influence of political aspects of resource allocation which such models cannot address. We also reflect on the need for advanced modelling to recognise the abilities of the users and the availability of realistic assumptions if they are to influence the practices of disaster managers.
