As 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 a b с d 00 +100 Duration (minutes) 0.2 0.4 0.2 0.4 1.2 1.2 1.0 The minimum cycle time The maximum cycle time Calculated cycle time a. Determine the minimum cycle time, the maximum cycle time, and the calculated cycle time. (Round your answers to 1 decimal place.) Minimum number of stations Immediate Predecessor d C Work stations Following Tasks I || ||| IV f b. Determine the minimum number of stations needed. (Round your answer to the next whole number.) Percentage of idle time 20 minutes per unit 30 minutes per unit minutes per unit c. 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. 1 d. Compute the percentage of idle time for the assignment in part d. Use the actual bottleneck cycle time in your calculation. (Round your answer to 2 decimal places.) %
