Labor and Setup Costs for Stretch Forming
The processes Bench Operation, Stretch Form, Cold Storage and Router use the formulas in this section (but note that in the absence of manual forming, setup cost is 0 for Bench Operation):
Labor Cost = Labor Time * Labor Rate / Final Yield
Labor cost depends on the following:
• Labor time (see formula below)
• Labor rate (specified as a machine property)
• Final yield (see Yields for Stretch Forming)
Labor Time = Cycle Time * Number of Operators * Labor Time Standard
Labor time (except for the Cold Storage process) is the product of the following:
• Cycle time (see process-specific Cycle Time formulas)
• 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.
See also Formulas for the Cold Storage Process.
Amortized Batch Setup =
(Setup Time * (Labor Rate + Direct Overhead Rate)) / Batch Size
Batch setup cost per part depends on the following:
• Setup time (specified as the machine property Setup Time)
• Labor rate (specified by the machine property Labor Rate)
• Direct overhead rate (see Direct and Indirect Overhead)
• Batch size (specified in the Production Scenario screen of the Cost Guide)
In the absence of manual forming, setup cost is 0 for Bench Operation.
