Resilience requirements
Service levels under defined hazards, such as hours of supply to hospitals during a grid outage, are written as verifiable requirements for designers and operators.
GCRI · 关键基础设施
系统 engineering treats infrastructure as a system of systems with requirements, interfaces and life cycles. In this field it defines what services must deliver under stress, traces those requirements to assets and interfaces, and verifies them.
系统 engineering is an interdisciplinary approach to designing and managing complex systems over their life cycle. It focuses on requirements, interfaces and interactions so that the whole performs as intended. In 关键基础设施 and cities and built environment, systems engineering exposes interfaces where failures propagate between components and organisations. It supports designing interconnected infrastructure with explicit dependency management. The canonical description is on STEM Commons.
Service levels under defined hazards, such as hours of supply to hospitals during a grid outage, are written as verifiable requirements for designers and operators.
Interfaces between infrastructure systems, such as power feeds to pumping stations, are documented with their owners and failure modes.
Requirements are verified at design review, at commissioning and in operation, through tests, inspections and exercises run with the operator.

贯穿六大支柱,由 Nexus Consortium 牵头
Each requirement is traced to verification evidence from analysis, inspection, demonstration or test. Independent reviews check completeness at life cycle gates.
| 核查 | 如何开展 |
|---|---|
| Requirement traceability | Each requirement is traced to design elements and tests |
| Interface ownership | Every interface has a named owner on both sides |
| Operational verification | Requirements are re-verified after major changes |
Emergent behaviour in open or socio-technical systems may not be captured by requirements. Rigid processes can slow adaptation to change.
Assembled from the Nexus Standards area profile 关键基础设施与关键实体: the hazards it names, the 系统 and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.
