Simulation

Overview

Simulation mode lets you explore how the destination could respond to a change in conditions. Start with the live state, then test a scenario such as increased arrivals, fewer available vehicles, or a wind shift over the reef. The forecast helps identify where capacity or operating limits may be reached; it is a planning aid, not a precise prediction of the future.

For example, increasing arrivals in a scenario may reveal a shortfall in transfer capacity. You can review that forecast and compare responses while there is still time to change the schedule, adjust the fleet, review a route or revise the marine plan.

How a run works

Choose a simulation and scenario preset, adjust the available inputs, then run the forecast. The controls are predefined; you do not write a model or a freeform scenario. Recommended responses preview their modelled effects without dispatching an action. The final option, Do nothing, keeps the modelled outcome unchanged or, in the energy simulation, follows the projected worst case.

Read the screen from left to right: the setup defines the scenario, the map shows where its effects occur, and the forecast panel explains the expected outcome and available responses.

Crowd and Traffic simulations currently use an earlier workflow: operators select a prepared event and action plan, which can be dispatched. These simulations are being redesigned to use the preview workflow described here.

The page at a glance

The standard simulation layout has three columns. The controls and metrics change with the simulation, but their positions stay the same:

  • Setup, on the left: choose the simulation, preset, input values, and visible layers. Select Run Simulation to start the forecast.
  • Digital twin, in the centre: view the forecast on Shura Island as a heatmap, wind field, or coastal overlay. The map shows where the predicted conditions occur.
  • Forecast, on the right: review the outcome banner, main metric, supporting KPIs, and recommended responses, including Do nothing.

The working area moves through two states, from setup to run.

Default, setup. Set the scenario on the left while the map shows live conditions. The outcome reads Not running and the forecast metrics are empty. Review this baseline before starting the run.

Running, the forecast. The map displays predicted conditions, such as wind above a limit, surge water reaching the marina, or reduced shade. The right panel shows the outcome, metrics, and response options. Select a response to preview its modelled effect without dispatching it.

Where the models come from

Specialist engines provide the models used by the IOC. Modelling and calibration take place in those tools; the IOC lets an operator select a prepared scenario and view its forecast on the twin.

The left side of this diagram shows the specialist engines and the presets and inputs prepared outside the IOC. The right side shows the operator workflow: set up a scenario, run it, and review its forecast and responses on the map.

The engine behind each read

Different roles use the same engine output to answer different questions. A wind forecast can help Guest Experience assess exposed decks, Operations review closure thresholds, and Marine Operations plan small-craft departures.

The grid groups simulations by domain and persona. Each entry identifies the specialist engine and the results relevant to that role.
