B.18 7 Boston's famous Limoges Restaurant is open 24 hours a day. Servers report for duty at 3 A.M., 7 A.M., 11 A.M., 3.M., 7., or 11 r.m., and cach 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 NUMBER OF SERVERS REQUIRED 1 3 A.M.-7 A.M. 3 2 7 AM -11 AM 12 3 11 AM -3 PM 16 3 P.M.-7.M. 9 5 7 P.M.-11 PM 11 M.-3.A.M. Owner Michelle Limoges' 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, equal the number of servers beginning work in time period-i, where i = 1, 2, 3, 4, 5, 6) 4 11 6 Hints: Six variables and six constraints. Don't ignore hint above-each variable is how many servers stort at a given time, not how many are working at that time
