## What is IE Calculator?

IE Calculator is an application designed for Industrial Engineering that allows easy calculation to support the manufacturing planning.
After setting the working pattern you are able to make the following calculations:
- Production Capacity based on the cycle time or Jobs Per Hour(JPH).
- Takt Time according to the volume demand. It can be yearly, monthly, weekly, daily or hourly demand.
- Actual JPH(Jobs Per Hour) based on the start time and the end time.
- HPU(Hours Per Unit) - The time required to produce one unit in the manufacturing process.

I hope you enjoy the app.
