Asset managers are facing the challenges of shrinking budgets from one side and the increasing frequency and impact of disturbances on their assets from the other side. To further equip asset managers to address these challenges, we propose an analytical framework for resilient asset management based on an extension to the established analytical framework of resilience. The core concept of this extension is to understand the significance of two types of couplings, including: (i) the coupled impact of different categories of disturbances, including shocks and stressors, and (ii) the chronological coupling of events in life cycle of an asset. A dynamic model of the proposed framework for integrating resilience into regular asset management is developed for building facilities and is integrated with mathematical modeling of stressors and randomly generated shocks. The model is then simulated as the results pointed to the need to offset the overestimation of the resilience of assets by integrating the coupled impact of shocks and stressors and the compounding impact of multiple potential disturbances in its life cycle. The proposed approach can extend the existing asset management models to future proof the plans for the life cycle of an asset and align the maintenance, repair, or rehabilitation actions with the actions associated with resilience enhancement retrofits.

将弹性整合到专注于建设设施的资产管理中

资产管理公司正面临着一方面缩减预算的挑战,另一方面则干扰对其资产的频率和影响日益增加。为了进一步装备资产管理公司以应对这些挑战,我们提出了一个基于对已建立的弹性分析框架的扩展的弹性资产管理分析框架。这个扩展的核心概念是理解两类耦合的重要性,包括:(i) 不同类别干扰的耦合影响,包括冲击和压力源,以及 (ii) 事件在生命周期中的时间顺序耦合。资产。为建筑设施开发了一个将弹性整合到常规资产管理中的拟议框架的动态模型,并与压力源和随机产生的冲击的数学模型相结合。然后对该模型进行模拟,因为结果表明需要通过整合冲击和压力源的耦合影响以及资产生命周期中多种潜在干扰的复合影响来抵消对资产弹性的高估。提议的方法可以扩展现有的资产管理模型,以证明资产生命周期计划的未来证明,并使维护、维修或修复行动与与弹性增强改造相关的行动保持一致。然后对该模型进行模拟,因为结果表明需要通过整合冲击和压力源的耦合影响以及资产生命周期中多种潜在干扰的复合影响来抵消对资产弹性的高估。提议的方法可以扩展现有的资产管理模型,以证明资产生命周期计划的未来证明,并使维护、维修或修复行动与与弹性增强改造相关的行动保持一致。然后对该模型进行模拟,因为结果表明需要通过整合冲击和压力源的耦合影响以及资产生命周期中多种潜在干扰的复合影响来抵消对资产弹性的高估。提议的方法可以扩展现有的资产管理模型,以证明资产生命周期计划的未来证明,并使维护、维修或修复行动与与弹性增强改造相关的行动保持一致。
