Abstract

This paper presents a multi-tier methodology for understanding the cascading impacts of hazards on the internal operations of a facility. Building Information Modeling (BIM) is utilized to create a 3D representation of a facility where each building element is linked with its design, operation, and maintenance data. The building data stored inside BIM is processed by the interdependency model to build an interdependency map. This is linked to a simulation engine built to consider the effect of deterioration of building elements on the processes housed inside a facility. The simulation engine adjusts the likelihood of failure of each building element based on its deterioration rate and the occurrence of hazardous events, if applicable. The output is a risk profile showing the cumulative likelihood of failure for each building element at each time step of the simulation, considering the spatial and operational interdependencies. A case study for a power plant facility in Ontario, Canada, is used to demonstrate and discuss the methodology. Owners, operators, and stakeholders can utilize the methodology to visualize the cascading effects of hazards on capital intensive facilities using an interactive simulation environment.

摘要

本文提出了一种多层方法，用于了解危害对设施内部运营的级联影响。建筑信息模型 (BIM) 用于创建设施的 3D 表示，其中每个建筑元素都与其设计、运营和维护数据相关联。存储在 BIM 中的建筑数据由相互依赖模型处理以构建相互依赖图。这与一个模拟引擎相关联，该引擎旨在考虑建筑元件退化对设施内流程的影响。如果适用，模拟引擎会根据每个建筑元件的劣化率和危险事件的发生来调整其失效的可能性。输出是一个风险概况，显示在模拟的每个时间步中每个建筑元素的累积失效可能性，考虑到空间和操作的相互依赖性。加拿大安大略省一家发电厂设施的案例研究用于演示和讨论该方法。业主、运营商和利益相关者可以利用该方法通过交互式模拟环境可视化危害对资本密集型设施的级联影响。
