QUESTION 7 Give the decision variables are defined as following: Pi: number of employee in shift i; i=1,2,3,4,5,6 Shift Time 12 am to 8 am 1 2 4 am to 12 pm 3 8 am to 4 pm 12 pm to 8 pm 5 4 pm to 12 am 6 8 pm to 4 am What is the objective function? OA. Min (P1+P2+P3+P4+P5+P6) OB. Max (P1+P2+1.5P3+1.5P4+2P5+2P6) OC. Min (P1+P2+1.5P3+1.5P4+2P5+2P6) OD. Max (P1+P2+P3+P4+P5+P6) QUESTION 8 Draw a picture like what we did in the lecture video. Which shifts will cover 12 am to 4 am? OA. Shift 1 and 2. B. Shift 1 and 6. C. Shift 4 and 5. D. Shift 1, 5, and 6. QUESTION 9 Which constraint ensures there are enough people between 12 pm to 4 pm? OA. P3+P5 165 B. P3+P4 165 OC. P2+P4 165 D.P3+P4 165 QUESTION 10 Which constraint ensures there are enough people between 4 am to 8 am? OA. P2+P4 215 OB. P3+P5215 OC. P3+P4 165 OD.P1+P2215 QUESTION 6 Q6 to Q10 are based on this problem. Maintenance at a major theme park in central Florida is an on-going process that occurs 24 hours a day. Because it is a long drive from most residential areas to the park, employees do not like to work shifts of fewer than eight hours. These 8-hour shifts start every four hours throughout the day. The number of maintenance workers needed at different times throughout the day varies. The following table summarizes the minimum number of employees needed in each 4-hour time period Time Period Minimum Employees Needed 12 am to 4 am 90 4 am to 8 am 215 8 am to 12 pm 250 12pm to 4 pm 165 4pm to 8 pm 300 8pm to 12 am 125 The maintenance supervisor wants to determine the minimum number of employees to schedule that meets the minimum staffing requirements. Formulate an LP model for this problem. I suggest you write down the complete formulation, including decision variables, objective function, and constraints first before you answer the multiple-choice questions. Which can not be the decision variable? OA. Number of People hired between 12 am to 8 am B. The minimum employees needed between 12 am to 4 am. O C. The total number of people hired between 8 am to 4 pm OD. The total number of people hired to cover 4 am to 12 pm.
