Heres how ClickUp can help you calculate cycle time and use it to your advantage. Definition Continuous Capacity the continuous passes per hour are determined from swing time and this multiplied by bucket capacity gives the hourly production capacity that would be expected. The formula for calculating Cycle Time is as follows: CYCLE TIME = Net Production Time / UNITS PRODUCED. From calculations, it is clearly seen that if the RR could be reduced to 2% on every road segment, then each cycle period per truck can be reduced by 1.24 minutes.
