This is a working-version of a tool that can be used to compare the net present value (NPV) cost of bus procurement options (e.g. diesel bus vs. electric bus). The Shiny app can be viewed at: https://michele-zemplenyi.shinyapps.io/fleetnpv_shiny/.
The tool uses a simulation approach to perform sensitivity analyses for the diesel price (
To use this tool, enter global inputs and procurement inputs in the tabs above. After clicking 'Run simulation,' a histogram displaying the difference in NPV costs across all simulations will appear below.
Note that the current version of this tool only accounts for a small subset of the costs of purchasing and operating a bus; future updates will include additional cost inputs (e.g. maintenance, financing) and the ability to specify other distributions for the diesel and electricity prices.
