Formulas for the Cold Storage Process

Labor Time = Handling Time * Number of Operators * Labor Time Standard

Labor time (except for the Cold Storage process) is the product of the following:

• Handling time: this is load and unload time. Each time is looked up by blank mass in the lookup table tblMaterialHandling.

• Number of operators (specified as a machine property)

• Labor time standard: specified as 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 = Handling Time + Storage Time

• Handling time: this is load and unload time. Each time is looked up by blank mass in the lookup table tblMaterialHandling.

• Storage time: by default this is specified by the cost model variable defaultColdStorageTime (24 hours in starting point VPEs). Users can override the default with the setup option Cold Storage Time.
