The concept of system robustness is scrutinized with the objective of integrating it into a decision analytical framework. A stochastic interpretation of robustness refers to the ability of systems (engineering, environmental, human systems) to confront unexpected or exceptional hazards without causing excessive consequences to the system constituents. Robustness involves casual events, propagating and indirect consequences, and extreme events. It is therefore amenable to quantitative risk analysis and decision making which includes the planning and optimization of infrastructural design, inspection and maintenance. The key framework of analysis is the use of hierarchical system models, which consist of sub-models or components that are not only logically and stochastically linked but also allow for consequences and risk to be passed on and shared.

系统的鲁棒性的概念进行审查，其目标是将其集成到一个决策分析框架。鲁棒性的随机解释是指系统（工程，环境，人类系统）面对意外或异常危险而不会对系统组成造成过度后果的能力。鲁棒性包括偶然事件、传播和间接后果以及极端事件。因此，它适合定量风险分析和决策，包括基础设施设计、检查和维护的规划和优化。分析的关键框架是使用分层系统模型，其中包括子模型或组件，不仅在逻辑上和随机联系，而且还允许后果和风险被传递和分担。
