You manage a 24-hour store where workers can come in at the beginning of any 4 hour interval, starting at midnight, and work an 8-hour shift. Based on store activity levels, the numbers of employees needed during the different 4-hour intervals in the day are given below. Time range 12:00 - 4:00 AM 4:00 - 8:00 AM 8:00 - 12:00 Noon 12:00 - 4:00 PM 4:00 - 8:00 PM 8:00 - 12:00 Midnight # Employees Needed 6 9 12 10 18 14 What would happen to decision variables if there were a requirement to have at least 3 male workers and 3 female workers per shift? Question 20 options: You would need the decision variables Nothing, that is a constraint You would need double the decision variables It would cause the problem to become unfeasible (no optimal solution would exist)
