2. The manager has been asked to balance an assembly line to achieve an output of 240 units per eight hour day. Task times and precedence is as follows: Tasks Times (mnt) Follower a 0.2 b b 0.4 C C 0.2 f d 0.4 e e 1.2 g f 1.2 1.01 g end a) Draw precedence diagram and find the cycle time (2 minutes) b) Determine theoretical number of work stations needed (3). c) Assign tasks to stations and break ties using these rules: First, greatest followers; then longest processing time. If tie still persists, choose arbitrarily. d) Compute percentage of idle time and efficiency of the line. I
