"Crop rate" refers to the proportion of time that equipment takes up in order to create value in the time it can provide. At the same time, according to the domestic manufacturing level, the crop rate A and crop rate B were created by Amy, who has 10 years of IE experience, and are vigorously promoted in the assessment department.
Here A is understood to be the ratio of the actual crop time to the idealized calendar date (idealized potential exploitation), and B is the ratio of the actual crop time to the production plan that can be invested (management and process potential exploitation), and each indicator brings different impacts on the decision-making of the enterprise.
Expanded Information:
Time Crop Ratio is the ratio of the time spent actually producing goods (crop time) relative to the time spent in production (load time). It is obtained by dividing the time of operation of machinery and equipment by the maximum load time.
And the cycle time is the load time minus the time for mold change, tool change, breakdown, and adjustment. Therefore, in order to improve the yield, it is necessary to reduce the lost time of mold change, tool change, failure, adjustment. If these lost time can be reduced to zero, then the crop rate can reach 100%.
