This study describes the application of multi-criteria decision analysis (MCDA) to prioritise the seismic risk mitigation of existing buildings in earthquake-prone Wellington, New Zealand. Through retrofitting or demolition, this is an important requirement in many cities around the Pacific Rim and in other high-level seismic hazard locations. The prioritisation strategy proposed here, based on MCDA methods, can provide decision-makers with a fast and reliable support tool for identifying the optimal sequencing of their retrofitting programmes. The premise of the MCDA analysis presented in this paper is that there are multiple criteria that determine societal prioritisation preferences; these are limited not just to life safety (often the explicit/exclusive priority of governments) and commercial value (the main concern of many building owners). The study demonstrates how different measures, within four general criteria—life safety and geo-spatial, economic, and socio-cultural roles—can be operationalised as a viable framework for establishing intervention policy priorities.

优先考虑新西兰惠灵顿的地震改造

本研究描述了多标准决策分析 (MCDA) 的应用，以优先减轻新西兰惠灵顿地震多发地区现有建筑物的地震风险。通过改造或拆除，这是环太平洋地区许多城市和其他高地震危险地区的重要要求。此处提出的优先排序策略基于 MCDA 方法，可为决策者提供快速可靠的支持工具，用于确定改造计划的最佳顺序。本文提出的 MCDA 分析的前提是，有多个标准可以确定社会优先排序偏好；这些不仅限于生命安全（通常是政府明确/排他的优先事项）和商业价值（许多建筑业主的主要关注点）。
