Assignment:
Wichita’s famous Sethi Restaurant is open 24 hours a day. Servers report for duty at 3 a.m., 7 a.m., 11 a.m., 3 p.m., 7 p.m., or 11 p.m., and each works an 8-hour shift. The following table shows the minimum number of workers needed during the 6 periods into which the day is divided:
Period Time No. of servers required
1 3AM - 7AM 3
2 7AM - 11AM 12
3 11AM - 3AM 16
4 3PM - 7PM 9
5 7PM - 11PM 11
6 11PM - 3AM 4
Owner Avanti Sethi’s scheduling problem is to determine how many servers should report for work at the start of each time period in order to minimize the total staff required for one day’s operation. (Hint: Let X i equal the number of servers beginning work in time period i , where i 5 1, 2, 3, 4, 5, 6.)
Provide complete and step by step solution for the question and show calculations and use formulas.
