Good day rizvisa1,
Referring to your questions, here is what I am facing. We have break down the daily work hours into 20-minutes intervals. The production time for 1pc is 4.5 seconds, which means we can produce 266pcs in 20 minutes. Thus, we need to break down the daily plan into groups where each group is of 20-minutes intervals and the quantity can be produced cannot exceed 266pcs. If the quantity of an item exceeded 266pcs, the balance needs to go into the next group of 20-minutes interval.
In the attached file, I have provided the result expected from the data.
Hope this clears the doubt.
Thank you in advance for your help.
