Perancangan skenario dan uji tekanan

Scenario design and stress testing are the method this platform stewards for the network. They turn severe but plausible events into structured tests of plans, buffers and dependencies. In risiko sistemik management they are used to probe cross-sector cascades, to find breaking points and to compare preparedness across institutions on common assumptions.

What scenario design and stress testing does here.

Scenario design and stress testing construct plausible, severe future conditions to examine how sistem and institutions would perform. They complement probabilistic analysis where data are scarce or futures are deeply uncertain. In risk management and risiko sistemik and methods and modelling, stress tests reveal vulnerabilities that arise when several risks materialise together. They inform capital, contingency and coordination plans across sectors. The canonical description is on STEM Commons.

Cross-sector scenario design

Scenarios are built with a trigger, severity, timing and conditions, then traced through the dependencies of energy, water, communications, finance and public services, with every assumption written down.

Reverse stress testing

Starting from a defined failure, such as a service stopping, analysts search for combinations of events that would cause it and document which ones are plausible.

Second-round effects

Tests add the reactions of institutions during a crisis, such as asset sales, supply hoarding or service cuts, to see how responses amplify or dampen the initial shock.

03Simulator

Stok, aliran, jeda, dan ambang titik balik.

Dua stok, tekanan dan kapasitas adaptif, dihubungkan oleh lingkar pertumbuhan yang saling menguatkan, respons penyeimbang yang tertunda, dan kerusakan ketika tekanan melampaui kapasitas; melewati ambang, sistem dapat berbalik. Model pengajaran dengan nilai ilustratif yang dinyatakan, bukan prediksi.

Data

No observed data enters this model: it runs on the teaching values set by the controls, to be replaced with a programme’s own evidence.

06Validasi

Cara hasil diperiksa.

Scenarios are reviewed for plausibility, internal consistency and severity relative to history. Exercise outcomes are compared with actual events when they occur.

Plausibility reviewScenarios are reviewed by domain experts for internal consistency and plausibility before use
Severity benchmarkingScenario severity is compared with historical events and published reference scenarios
Model coverageThe share of mapped critical dependencies represented in the test is reported with the results

Scenario choice can reflect prevailing assumptions and miss novel combinations. Results depend on how participants and models represent responses.
