## What is Spares Scaling?

The application calculates, by Monte Carlo Simulation, the fleet availability (Service Level - SL) achieved by operating a number of fleet assets under specified scenarios. Each scenario examines a single repairable component/unit of the asset for which a specified number of spares (rotables) are kept in stock.
Inputs required are the number of fleet assets, the annual rate of fleet operational usage (e.g. 2000 hours per year), the number of installed components per asset, the number of spare components kept, the reliability of the component and finally its time Turn Around Time (TAT). This is the time needed to repair the failed component/unit and return it as serviceable back in the warehouse.

This app has nothing to do with screen scaling. It shows that Apple lets scammers apps on Mac.

## Frequently asked questions about Spares Scaling

### What is Spares Scaling used for?

Spares Scaling is used to calculate fleet availability (Service Level) by simulating various operational scenarios. It helps determine the optimal number of spare parts needed to maintain desired service levels for repairable components.

### What inputs are required for Spares Scaling?

You need to input the number of fleet assets, annual operational usage, components per asset, number of spare components, component reliability, and the repair Turn Around Time (TAT).

### How does Spares Scaling calculate fleet availability?

It utilizes Monte Carlo Simulation to model the behavior of fleet assets and their components over time, factoring in failure rates and repair times to predict the achievable Service Level.
