There is an upstream Picking department that feeds two downstream Packing departments: Pack Singles and Pack Multis. Those Packing departments feed to a Shipping department that loads the outgoing trucks. 40% of your Pick volume goes to Pack Singles and has a packing rate of 104 units per labor hour (uph). 60% of the Pick volume goes to Pack Multis and has a pack rate of 215 units per labor hour. Your pickers pick both Single and Multi items throughout the day at an overall average rate of 114 units per labor hour. All units that are packed in both processes go through the Ship process at a rate of 570 units per hour. You have 102 people today for all 4 departments and you absolutely must pack 47,880 units in Pack Multis Items to meet a customer promise metric.

Redirect 1: You now need to process all of the Pack Singles Volume in the first 5 hours of the shift. All of the constraints and parameters are the same as the original problem. Again, assuming no breaks and lunches. How do you allocate your staffing for the first 5 hours of the shift for all departments? How do you allocate your staffing for the second 5 hours of the shift for all departments?

Redirect 2: Your Pack Multis Volume reduces to 200 - from which department do you redistribute staff?
