Problem 8-9 (Static) An assembly line is to be designed to operate 772 hours per day and supply a steady demand of 300 units per day. Here are the tasks and their performance times: PRECEDING PRECEDING TASKS TASK PERFORMANCE TIME (SECONDS) 70 TASK TASKS PERFORMANCE TIME (SECONDS) 60 a d g h b 40 e 50 45 i f 15 d a 10 g 25 b 30 i k 1 20 h, i i, k f 20 25 d. Assign tasks to workstations using the longest operating time. (Leave no cells blank - be certain to enter "0" wherever required.) Work Station Task Idle Time I 20 X II a-d 5 III e-h 10 IV x 25 f-i-k-1 9-1 V 5 f. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 772 hours per day in regular time. (Round your answers to the nearest whole number.) Reduce cycle time to 82 seconds per unit. Another option is to work 8 x minutes overtime
