The estimated cost of fire in the United States is about $329 billion a year, yet there are gaps in the literature to measure the effectiveness of investment and to allocate resources optimally in fire protection. This article fills these gaps by creating data-driven empirical and theoretical models to study the effectiveness of nationwide fire protection investment in reducing economic and human losses. The regression between investment and loss vulnerability shows high R values (≈0.93). This article also contributes to the literature by modeling strategic (national-level or state-level) resource allocation (RA) for fire protection with equity-efficiency trade-off considerations, while existing literature focuses on operational-level RA. This model and its numerical analyses provide techniques and insights to aid the strategic decision-making process. The results from this model are used to calculate fire risk scores for various geographic regions, which can be used as an indicator of fire risk. A case study of federal fire grant allocation is used to validate and show the utility of the optimal RA model. The results also identify potential underinvestment and overinvestment in fire protection in certain regions. This article presents scenarios in which the model presented outperforms the existing RA scheme, when compared in terms of the correlation of resources allocated with actual number of fire incidents. This article provides some novel insights to policymakers and analysts in fire protection and safety that would help in mitigating economic costs and saving lives.
美国每年火灾造成的损失估计约为 3290 亿美元,但在评估投资效果和优化资源配置以实现最佳消防保护方面仍存在差距。本文通过建立数据驱动的实证和理论模型,研究了全国性消防投资在减少经济和人员损失方面的效果,填补了这一空白。投资与损失脆弱性之间的回归显示出很高的 R 值(≈0.93)。本文还通过建模来研究战略性(国家级或州级)资源分配(RA),同时考虑公平与效率之间的权衡,这是现有文献中很少关注的问题,而现有文献主要集中在运营层面的 RA。该模型及其数值分析为辅助战略决策过程提供了技术和见解。该模型的结果用于计算各个地理区域的火灾风险评分,可作为火灾风险的指标。本文还使用联邦消防拨款分配案例研究进行了验证,并展示了最优 RA 模型的实用性。结果还确定了某些地区在消防保护方面存在潜在的投资不足和过度投资的情况。与现有 RA 方案相比,本文提出的方案在资源分配与实际火灾事件数量的相关性方面表现更优。本文为消防和安全领域的政策制定者和分析师提供了一些新颖的见解,有助于减轻经济成本和拯救生命。
