The Manufacturing Cost Model (ManuCostModel) is a python package developed for technical cost modelling of the manufacturing costs for products made from fibre-reinforced composite materials.

ManuCostModel was developed for a generic aircraft wing design, consisting of a structural I-beam spar supporting an aerodynamic skin. The design is also applicable to a standard wind turbine blade construction.

Installation on Windows:

The following outlines an example analysis case using ManuCostModel:

# Import the library
import ManuCostModel as mcm

# Provide a path to the directory where the input files can be found
directory = "...your_path_here"

# Provide a name for the manufacturing database (if different from the default)
inputFileName = "manufacturingDatabase"

# Set up the manufacture class object (this can be considered the "factory")
wingProduction = mcm.CostModel.Manufacture(directory, inputFile=inputFileName)

# Analyse the production costs
# scaling is True if the model determines its own geometric scaling variables
wingProduction.productionRun(scaling=True)

# Use the toolset to create a data object from the analysis results
plotData = mcm.Tools.costCentres(wingProduction, totals=True, stacked=True)

# Produce a pie chart of the main cost centres for the product
mcm.DataVis.pieChart(plotData)
