How to run a simulation
To run a simulation in Shoreline, configure your case with bases, logistics, personnel, and strategy, then follow these steps:
- Open a Shoreline simulation case.
- Click the Simulate tab.
- Choose your simulation settings.
- Click Run simulation.
Simulation settings
| Setting | Description |
|---|---|
| Weather | Controls how the weather data in your case is applied across simulation runs. For example, weather data can be set to cycle through available years sequentially or be sampled randomly. |
| Start year | Note: O&M only. The year from which operations will begin in the simulation. |
| Start date | Note: Construction only. The date from which the construction campaign will begin in the simulation. This is the date on which the first task is carried out. |
| Years | Note: O&M only. How many years you want your O&M schedule to run. |
| Runs | How many simulations you want to run using the same settings. Simulation runs are run as a batch and used to calculate percentiles. See the How many simulation runs should I use? section below for more details. |
How many simulation runs should I use?
O&M
The complexity of the simulated events can affect the number of runs required. More complex cases (such as those with MCRs) may require more runs to achieve convergence.As a general guideline, simpler cases may converge with as few as 20–30 runs, while highly complex cases with multiple MCRs may require 100 or more.
If you are unsure how many runs you require, it is best to start with a moderate number (~50 runs) and increase the number gradually until you observe convergence.
Construction
For construction simulations, run the same number of simulations as the number of overlapping years in your weather data. For example, if your weather datasets share 10 overlapping years, use 10 simulation runs.
