Resilience investment portfolios
Combinations of hardening, redundancy and backup projects are selected to reduce expected service loss across scenarios within a budget.
GCRI · Binesaziya girîng
Optimisation and operations research choose the best use of limited budgets, crews and capacity. In this field they prioritise investments in resilience, schedule restoration and plan network expansion under uncertainty.
Optimisation and operations research develop mathematical methods for allocating resources and making decisions under constraints. They support planning and logistics in complex, interconnected pergalan. In binesaziya girîng and cities and built environment, optimisation supports prepositioning of supplies, network investment and recovery sequencing. Robust formulations help choose options that perform acceptably across many scenarios. The canonical description is on STEM Commons.
Combinations of hardening, redundancy and backup projects are selected to reduce expected service loss across scenarios within a budget.
Repair crews and sequences are optimised to restore critical services fastest given dependencies and access.
Stochastic and robust optimisation choose network expansions that perform acceptably across many demand and hazard scenarios, not only the expected one.

Solutions are checked for feasibility, tested through simulation and compared with historical decisions. Analîza hesasiyetê examines how results change with parameters.
| Kontrol bikin | How it is done |
|---|---|
| Scenario coverage | Solutions are tested on scenarios not used for optimisation |
| Constraint validation | Constraints are confirmed with operators |
| Solution stability | Small changes in inputs are tested for large changes in the chosen portfolio |
Optimal solutions can be fragile when assumptions are wrong. Objectives may omit values that are hard to quantify.

Li seranserê şeş stûnan, bi pêşengiya Nexus Consortium
Assembled from the Nexus Standards area profile Critical infrastructure and critical entities: the hazards it names, the pergalan 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.

Zanista pergalan û modelkirin stewards optimisation and operations research for the Consortium and reviews how it is applied across platforms.
