Calculate Cycle Time

Contents



How is Cycle Time defined?

Cycle time is defined as the time elapsed between two baskets exiting the line when the line is fully loaded. This time is normally somewhat longer than the longest minimum residence time. The extra time is accounted for by robot movements, lids opening, etc.

How is Cycle Time calculated?

The cycle time is typically calculated for the basket sequence taking the longest time. In a line with more than one robot, each robot will have its own cycle time. The cycle time for the basket sequence will never be shorter than that of the longest robot cycle time. Ideally, the cycle times of the robots should be equal, giving the cycle time of the basket sequence in question. The cycle time calculation must be performed for one robot at a time. This can be done by creating installations that are the relevant fragments for each robot. Thus, it is possible to correct the basket sequence if any bottlenecks are identified. When bottlenecks have been reduced to a minimum, a full simulation will give the best approximation of cycle time for the basket sequence.

Columns in Cycle Time Window

Basket The basket for which the cycle time was calculated.
Total Total cycle time
Wait until the Corr value is 0 (zero) or that the Total Cycle Time has stabilized.
Move X Total time spent on X movements
Move Y Total time spent on Y movements
Wait T Total time spent waiting on Timers
Wait I Total time spent waiting on Inputs
Pause Total time spent on Pause
Idle Total time spent on other instructions
Corr Correction for graphical movements
Graphics, in average, are NOT finished before the calculated time for robot movements.
This correction is self-adjusting after each cycle. Wait until the Corr value is 0 (zero) or that the Total Cycle Time has stabilized.
Count Total instructions performed for the basket.
This count can vary by one or two depending on round-offs of timers.
