An assembly line is to be designed to operate 7'2 hours per day and supply a steady demand of 300 units per day. Here are the tasks and their performance times: PRECEDING TASKS TASK TASK A B PERFORMANCE TIME (SECONDS) 70 40 45 10 30 20 UIH PRECEDING TASKS D E F G H, I J, K PERFORMANCE TIME (SECONDS) 60 50 15 25 20 25 D E F B C 3 L b. What is the workstation cycle time required to meet the desired output rate? Workstation cycle time 90 seconds per unit c. What is the theoretical minimum number of workstations required to meet the desired output rate? (Round up your answer to the next whole number.) Minimum number of workstations d. Assign tasks to workstations using the longest operating time. Work Station I Task A-D Idle Time 10 5 II III 5 G-J C-B E-H F-I-K-L IV 10 V 10 e. What is the efficiency of your line balance, assuming It is running at the cycle time determined in part b? (Round your answer to 1 decimal place.) Efficiency % f. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 72 hours per day. (Round your answer for cycle time down to the nearest whole number. Round your answer for overtime up to the nearest whole number.) Reduce cycle time to seconds per unit. Another option is to work minutes overtime
