[Chapter 9: 20 points] An operation manager wants to assign tasks to workstations as efficiently as possible. Management desires an output rate of 40 units per day. The tasks shown in the following table are to be assigned to minimize the percentage of idle time. Assume 480 minutes are available per day. a. Draw a precedence diagram of this operation. Determine the appropriate cycle time. What is the theoretical minimum number of workstations? Assign tasks to workstations using longesi operation time. What is the actual number of stations? How much total idle time is present each day? What is the overall efficiency of the assembly line? b. What is/are the bottleneck task(s) of the assembly line if the operation manager assigns one employee per task? What is the hourly capacity of the line (in units per hour) if the operation manager assigns one employee per task? c. What are the minimum and maximum cycle times? What is an hourly range of theoretical output possible for this assembly line
