Quizplus · Accepted Answer

The cycle time can be calculated by dividing the total available time per day by the desired output rate. With 2 shifts per day, each 8 hours long, the total available time is 16 hours or 960 minutes (16 hours * 60 minutes/hour). Converting 960 minutes to seconds gives 57600 seconds (960 minutes * 60 seconds/minute). Dividing this by the desired output rate of 480 units per day gives a cycle time of 120 seconds (57600 seconds / 480 units = 120 seconds).
