aPriori uses the formulas below to determine costs associated with this process.

Accounting Calculations

Labor Time = Cycle Time * Machine Labor Time Standard

Labor time is the product of the following

• Cycle time (see Cycle Time Calculation)

• Machine labor time standard (specified as a machine property). This value reflects the amount of time spent by machine operators in between machine cycles, including time performing maintenance and cleaning tasks as well as time pausing between tasks. The amount is expressed as a cycle time multiplier.

Labor Cost = (Labor Time / 3600) * Labor Rate

Labor cost is a function of the following:

• Labor time (see formula above)

• Labor rate: this is the product of the following:

  • Machine property Labor Rate
  • Cost model variable laborRateAdjustmentFactor (1 in starting point Digital Factories)
  • Machine property Work Center Labor Rate Factor (1 in starting point Digital Factories)

Direct Overhead Cost = (Labor Time / 3600) *
Machine Overhead Rate

Direct overhead cost depends on the following:

• Labor time (see formula above)

• Machine overhead rate (specified as a machine property)

Amortized Batch Setup = (Machine Setup Time *
(Labor Rate +
Direct Overhead Rate)) / Batch Size

Amortized batch setup cost depends on the following:

• Machine setup time (specified as a machine property)

• Labor rate: this is the product of the following:

  • Machine property Labor Rate
  • Cost model variable laborRateAdjustmentFactor (1 in starting point Digital Factories)
  • Machine property Work Center Labor Rate Factor (1 in starting point Digital Factories)

• Direct overhead rate (see Direct and Indirect Overhead)

Cycle Time Calculation

Cycle Time = Part Edge Perimeter + Machine Perimeter Allowance

Cycle time is the sum of the following:

• Part edge perimeter (sum of the perimeters of each GCD operated on)

• Machine perimeter allowance (time per unit length, specified as a machine property)
