LightEdge Technologies would like to put in place an assembly line in its Mexican facility that puts together Internet servers. The tasks needed to accomplish this, including times and predecessor relationships, are as follows:



a. Draw a precedence diagram for the tasks. Suppose the takt time is 240 seconds (4 minutes). What is the theoretical minimum number of workstations?
b. Develop workstation assignments using the "largest eligible task" rule (i.e., assign the largest task that will fit into the workstation without exceeding the takt time).
c. How many workstations does your solution re quire? What is the cycle time for the line? What is the idle time?
