Upload and Calculate

Upload Cutting Plan Files or ZIP

You can select multiple files. Supported formats: .csv, .json, .xlsx, .xls, .zip

Yield File (Required when uploading files manually)

Format: "filename: yield_value" per line, or CSV with filename and yield columns. This is the yields.csv from Step 2.

Solving Time File (Optional)

Format: "filename: time_in_seconds" per line, or CSV. This is the solving_times.csv from Step 2.

Statistics to Calculate

Select which statistics categories to include (yield is always included):

Length Statistics - Statistics based on piece lengths weighted by demand Demand Statistics - Statistics based on demand values Length × Demand Statistics - Statistics based on total material per length Solving Time - Include optimization solving time in output (optional)

Each statistics category includes: mean, max, min, median, mode, std_dev, skewness, kurtosis, quartiles, IQR
