b. If the daily (24-hour) production rate is 96 units, what is
the greatest possible cycle time?
c. If the cycle time after allowances is given as 10 minutes,
what is the daily (24-hour) production rate?
d. With a 10-minute cycle time, what is the theoretical minimum

1. Balance delay" is another name for the percentage of idle time in a product layout. True False 2. The percentage of idle time in an assembly line is called cycle time. True False 3. For a production line, daily capacity can be determined by dividing the daily operating time by the line's cycle time. True False 4. Heuristic approaches (e.g. LOT, RPW) to line balancing are the only approach that will guarantee an optimal solution. True False 5. Cycle...
