Question: As a part of a major plant renovation project, the industrial engineering department has been asked to balance a revised assembly operation to achieve an output of 240 units per eight-hour day. Task times and precedence relationships are as follows:

Task Duration (Minutes) Precedes Task
a 0.2 b
b 0.4 c
c 0.2 f
d 0.4 e
e 1.2 g
f 1.2 g
g 1 end

Do each of the following:

  1. Draw the precedence diagram.
  2. Determine the minimum cycle time, the maximum cycle time, and the calculated cycle
    time.
  3. Determine the minimum number of stations needed
  4. Assign tasks to workstations on the basis of greatest number of following tasks. Use
    longest processing time as a tiebreaker. If ties still exist, assume indifference in choice
  5. Compute the percentage of idle time for the assignment in part d.
