4.1.1.1.2. bca_tool_code.engine_cost_modules.engine_package_cost module
- calc_avg_package_cost_per_step(settings, cost_object, vehicle, standardyear_id, labor=False)[source]
- Parameters:
settings – object; the SetInputs class object.
cost_object – object; an object of the PieceCost class (e.g., settings.engine_costs or settings.replacement_costs).
vehicle – object; an object of the Vehicle class.
standardyear_id – int; the implementation year associated with the cost.
labor – boolean; if True, a labor cost from the RepairAndMaintenance class will be included in the package cost.
- Returns:
Updates the engine_costs object dictionary to include the year-over-year package costs, including learning effects, associated with implementation of each new standard.
Note
Tech penetrations are applied here.
- calc_package_cost(settings, cost_object, vehicle)[source]
- Parameters:
settings – object; the SetInputs class object.
cost_object – object; an object of the PieceCost class (e.g., settings.engine_costs or settings.replacement_costs).
vehicle – object; an object of the Vehicle class.
- Returns:
The package average cost and package cost associated with the passed vehicle.
4.1.1.1.3. bca_tool_code.engine_cost_modules.indirect_cost module
- calc_project_markup_value(settings, vehicle, markup_factor_name)[source]
This function calculates the project markup value for the passed markup_factor (Warranty, RnD, Other, Profit).
- Parameters:
settings – object; the SetInputs class object.
vehicle – object; an object of the Vehicle class.
markup_factor_name – str; represents the name of the project markup factor value to return (warranty, r and d, other, etc.).
- Returns:
A single markup factor value to be used in the project having been adjusted in accordance with the proposed warranty and useful life changes and the Absolute/Relative scaling entries.
Note
The project markup factor differs from the input markup factors by scaling where that scaling (if applicable) is done based on the “Absolute” or “Relative” entries in the input file and by the scaling metric (Miles or Age) entries of the warranty/useful life input files. Whether Miles or Age is used is set via the BCA_General_Inputs file.
- calc_indirect_cost(settings, vehicle, pkg_cost)[source]
- Parameters:
settings – object; the SetInputs class object.
vehicle – object; an object of the Vehicle class.
pkg_cost – numeric; the direct manufacturing cost for the given vehicle.
- Returns:
A dictionary of indirect cost contributors and their values.
