Knockout Formulas

This process uses the following formulas:

Labor Time =

Labor Independent Process Time * Number of Operators * Labor Time Standard

Labor time is the product of the following:

• Labor-independent process time: see formula.

• Number of operators: specified by the machine property Number of Operators.

• Labor time standard: specified by the machine property Labor Time Standard. This multiplier is used to account for otherwise unaccounted for factors that affect labor time, such as operator fatigue or time spent by the operator for cleaning or maintenance.

Cycle Time = Labor Independent Process Time * Cycle Time Adjustment Factor

Cycle time depends on the following:

• Labor-independent process time: see formula.

• Cycle Time Adjustment factor (specified by the cost model variable cycleTimeAdjustmentFactor). This factor is 1 in aPriori starting point Digital Factories. Digital Factory Administrators can modify cycleTimeAdjustmentFactor in order to adjust cycle times across processes within the current Digital Factory.

Labor Independent Process Time =

Knockout Time + Process Load Time + Process Unload Time

Labor-independent process time is the sum of the following:

• Knockout time: specified by the cost model variable defaultCycleTime_knockOut (1200 seconds in starting point Digital Factories).

• Process load time: interpolated based on values looked up by tree weight (see Metal Pouring Machine Selection) in the lookup table tblHandlingTimes.

• Process unload time: interpolated based on values looked up by tree weight (see Metal Pouring Machine Selection) in the lookup table tblHandlingTimes.
