Calculations

Calculation Accuracies

These settings enable you to determine the level of accuracy you want to have applied in a calculation mode. The setting for the level of accuracy determines at what point FACTON will alert you when switching to a less accurate calculation mode. In addition, the levels of accuracy are also used to present the results in the "Mode Analysis" report.

Column	Description
Valuation	Displays the name of the calculation mode for which a level of accuracy is entered.
Part	Enter the accuracy of a calculation mode if it is applied to a part.
Material	Enter the accuracy of a calculation mode if it is applied to a material.
Manufacturing process	Enter the accuracy of a calculation mode if it is applied to a manufacturing process.
Additional costs	Enter the accuracy of a calculation mode if it is applied to additional costs.

"Basic" calculation mode

Reference in calculation

• "Resource" option

  Machine and labor costs are separately assessed in "Basic" calculation mode (default setting). Machine cost and workforce cost rates as well as machine and worker time are used to calculate manufacturing costs.

• "Process" option

  There is no separate assessment of machine and labor costs in "Basic" calculation mode . The manufacturing cost rate and production time are used to calculate manufacturing costs. Setup costs are assessed in a separate field.

Setup times

This setting determines the default reference unit used for the setup time and applies only when assessing work steps in "Basic" calculation mode .

• "Per n piece" option

  When selected, the lot size of the process is preset with n pieces. n is the amount entered in the input field.

• "Per lot" option

  When selected, the time entered is per lot.

Reference of lot size for calculation

Lots

• "Define lots at part" option:

  When selected, enter the number of lots at the part. Only this number of lots will be used. The default value is 1. The number of project lots from production planning is not taken into account.

• "Take-over lots from product" option

  When selected, the lots are taken from the Production Planning. This enables you to define different lot sizes for single calculation years. In this case, you cannot define the number of lots at the part.

• "Multiply lots at part by lots from product" option

  When selected, the lots are taken from the project. You can also define the number of lots for each part. The final number of lots at a part is calculated by multiplying the number of project lots by the number of part lots.

Cavities

• "Use cavities" checkbox

  This is a default value for the manual setting in the calculation modes. Activate the checkbox to use cavities in the calculation.

Basis data

• "Show column "Variable Portion"" checkbox

  This setting allows you to define the variable portion for each surcharge (material overhead, production overhead rates, etc.). The variable portion of the surcharge per year is set in the basic data. You can also adjust the share of variable costs in production planning for each project.

Manufacturing processes

• "Enter production parameters based on validity" checkbox

  Activate the checkbox to use validities for process parameters. This function is deactivated by default.

Inflation

• "Starting after the year of the last valid rate or price" option

  This option complies with the revised inflation calculation.

  The inflation takes effect from the date of the most recently valid price or tariff. Tariffs without validity are not considered in the inflation.

  A price or tariff valid until year X is included in the inflation of year X+2 with the inflation rates valid in X+1 and X+2, and is then provided for the calculation.

  As for purchased part prices and cost center tariffs, the value determination is being appraised before the inflation. For example, if (as defined in the settings) there is no price for year X, the future price for year X+2 is to be used. In this case, no inflation is calculated.

• "Starting after start of production (SOP + 1) option

  This option complies with the revised inflation calculation and is the default setting after database maintenance.

• "Wage inflation before SOP" checkbox

  Activate the checkbox to add wage inflation before the start of production to the labor costs from Data Administration. It is crucial to determine the start date of wage inflation in the basic data. Precondition: The inflation rates must be saved in the basic data (with location) in Data Administration.

  Note

  If the checkbox is activated, wage inflation only applies to work processes that have been evaluated in "Advanced" calculation mode . Labor costs that were entered in "Estimation" calculation mode or "Basic" calculation mode are not inflated before SOP.

• "Inflate manufacturing processes evaluated with "Technology" mode" checkbox

  Activate the checkbox to calculate wage inflation in the "Technology" calculation mode .

• "Inflate labor and setup costs for manufacturing processes evaluated with "Estimation" mode" checkbox

  Activate the checkbox to increase setup costs with a separate inflation rate (setup inflation).

  Deactivate this checkbox to use wage inflation to inflate setup costs.

  Note

  Setup inflation is an inflation rate that acts upon labor and machine costs during setup. A surcharge rate type "Inflation rate" and surcharge on "Setup inflation" must exist in the basic data in order to use setup inflation. Setup inflation acts on the "Estimation", "Basic", "Advanced" and "Technology" calculation mode (on processes). In "Estimation" calculation mode the setup inflation always applies.

  Note

  Setup inflation is only calculated for active projects. Existing versions are not changed when the option is turned on or off.

• "Inflate setup costs independently from machine and labor rate inflation" checkbox

  Activate the checkbox to calculate wage inflation in the "Estimation" calculation mode .

• "Use labor and machine inflation also for '"ost Center" mode" checkbox

  Activate the checkbox to calculate wage inflation in the "Cost Center" calculation mode .

Machine Depreciation and Interest

These settings are not active by default.

By activating, depreciation and interest at the hourly cost rate of the machine are also considered beyond the depreciation period. When changing the validity context in the Data Administration of the machine, the values for the imputed depreciation and imputed interest remain.

• "Activate on standard machine" checkbox

  Activate the checkbox to consider depreciation and interest for standard machines.

  Changes for these settings are only available after database synchronization or adding the machine again because standard machines are not recalculated in the project.

• "Activate on project-specific machine" checkbox

  Activate the checkbox to consider depreciation and interest for project-specific machines.
