THE UNIVERSAL GAUGE The VL Flex device can easily replicate every analog instrument thanks to the sun-readable 1.44” TFT display embedded into a standard 52 mm satellite instrument. The supported analog inputs allow you to directly read from your engine sensors, and the CAN interface expands this possibility by allowing the device to read from the digital network. The simple but effective graphic design can be set up in a single or dual layout, presenting the data in a clear and intuitive form. The colored bar graph and the alarm display allow you to visually understand your data. CONTACTLESS DEVICE CONFIGURATION (Patent Pending) The VL Flex configurator is the easiest way to configure your VL Flex device! Thanks to the contactless configuration you can setup your all-in-one instrument with a simple tap! Launch the App and define your settings through the user-friendly interface, then simply hold your mobile device in proximity of the VL Flex device to transfer the configuration. Thanks to the embedded passive antenna the configuration can be done powerless! Discover more on www.veratron.com
Spares Scaling
This app simulates fleet availability using Monte Carlo methods. It calculates service levels based on the number of fleet assets, component reliability, repair times, and spare parts inventory.
- Monte Carlo Simulation
- Fleet Availability Calculation
- Spare Parts Inventory Management
- Component Reliability Analysis
- Repair Time (TAT) Input
- Scenario-Based Analysis
Read full descriptionHide full description
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.
