提出了一种面向规划的、能有效应对多种自然灾害的抗灾能力评估与增强方法。提出了一个统一的灾害模拟框架，从各种潜在的灾害情景中提取关键信息，从而形成灾害情景数据库。采用基于影响增量的枚举法，建立了可重用的影响增量数据库，加快了评估过程。该数据库还可用于计算构件级的抗灾指数和经济指数，以便在规划时间尺度内制定针对潜在灾害的增强策略。在台湾沿海地震统计区的综合电力，天然气系统的弹性评估表明，所提出的方法可以显着提高计算效率相比，现有的方法。数值结果表明，考虑自然灾害类型多样性的抗灾规划能够全面提高系统的抗灾能力，即不只是关注单一灾害类型下的系统性能。此外，在资金不足的情况下，应根据经济指标制定最合适的抗灾能力增强方案，而不是根据无法平衡抗灾能力增强效果与实施成本的组件级抗灾能力指标。
A planning-oriented resilience assessment and enhancement approach is proposed that can efficiently deal with multi-type natural disasters. A unified disaster modelling framework is proposed to extract key information from various potential disaster scenarios, thus forming a disaster scenario database. The impact-increment-based enumeration method is applied, and a reusable impact-increment database is established to speed up the assessment process. The reusable database is also utilized to calculate component-level resilience indices and economic indices, so as to make enhancement strategies against potential disasters within planning time scale. Resilience assessment on an integrated electricity-gas system in Taiwan's coastal seismic statistical zone shows that the proposed method can significantly improve the computational efficiency as compared to existing methods. Numerical results indicate that the resilient planning considering the diversity of natural disaster types comprehensively improves the system resilience, which means it is not only concerned with the system performance under a single type of disaster. In addition, the most suitable resilience enhancement scheme with insufficient funds shall be developed according to the economic indices, instead of the component-level resilience indices that cannot balance the resilience enhancement effect with the implementation cost.
