Tailwind, Inc. produces high-quality but expensive training shoes for runners. Manufacturing the shoes requires ten separate tasks. There are 400 minutes available for manufacturing the shoes in the plant daily. Daily demand is 60. The information for tasks is as follows: Task Task Time (min) Immediate Predecessor Task Task Time (min) Immediate Predecessor A 1 F 3 A B 4 G 2 F C 2 B II 5 G D 4 B I I E 1 C. D J 3 E, H I a. Draw the precedence diagram. b. What is the theoretical workstation cycle time? c. What is the theoretical minimum number of workstations? d. Balance the line by using the "Ranked positional weight" and use "longest operation time" as a secondary criterion. Finally, write the sequence of each task in each workstation. e. What is the efficiency of your line balance? What is the total idle time? f. which Workstation(s) is (are) the bottleneck of the system? B- calculate the utilization of each station. h. Suppose demand increases by 10 percent. How would you react to this? Assume that you can operate only 400 minutes per day.
