- Summary
- A complete balance for fiber, water and
temperature was built for the whole mill. - First analysis for optimization on DIP 1
- 8 hours modeling work for different scenarios to
increase profitability on DIP 1. - 20 minutes for the management to understand the
problem and decide to do the investment.
