Use the following problem statement to answer questions 4-6. A department store has decided to stay open on a 24-hour basis. The store manager has divided the 24-hour day into six 4-hour periods. The beginning times for the shifts are 12:00 AM, 4:00 AM, 8:00 AM, 12:00 PM, 4:00 PM, and 8:00 PM. The minimum number of employees required in each period is as follows: 241 from 12:00 AM to 4:00 AM 193 from 4:00 AM to 8:00 AM 250 from 8:00 AM to 12:00 PM 244 from 12:00 PM to 4:00 PM 300 from 4:00 PM to 8:00 PM 215 from 8:00 PM to 12:00 AM . Personnel must report for work at the beginning of one of these times and work 8 consecutive hours. The store manager wants to know the minimum number of employees to assign for each 4- hour segment to minimize the total number of employees. [Note: Xi = no. of employees assigned to time period i, where i = 1, 2, 3, 4, 5, and 6 (time period 1 = 12:00 AM - 4:00 AM; time period 2 = 4:00 AM - 8:00 AM and so on).] [T/F] The objective function for the model is Min Z = X1 + X2 + X3 + X4+ X5 + X6. True False D Question 5 [T/F] One of the constraints for the model is X1 + X2 193. True O False Question 6 [T/F] One of the constraints for the model is X4+ X5 215. O True O False
