Waste Module
From Commander4j Wiki
The Waste Module is designed to allow you to record where waste is being generated in a manufacturing environment and then report on it so that you can easily determine which areas might benefit from improvement.
This module is part of Commander4j version 8.02 or newer and some example data has been included to illustrate how it can be configured. This is a totally fictitious factory so don't worry if it does not make any kind of sense from a manufacturing perspective.
