pip install topsis_Bhavya_Jaiswal_1022203087

Usage

Input File Format

The input CSV file should have the following structure:

• The first column should contain the names of the models.
• The subsequent columns should contain the criteria values for each alternative.
• The first row should contain the headers for each column.

Example:

model	Criteria 1	Criteria 2	Criteria 3	Criteria 4	Criteria 5	Criteria 6
A1	400	3.5	2500	80	7.2	150
A2	350	4.0	2600	85	6.8	170
A3	420	3.8	2550	78	7.5	160
A4	390	3.6	2480	82	7.0	155

Command-line Usage

After installation, you can use the topsis command in the terminal:

topsis <input_file> <weights> <impacts> <output_file>

• <input_file>: Path to the input CSV file.
• <weights>: Comma-separated string of weights for the criteria.
• <impacts>: Comma-separated string of '+' or '-' indicating the desirability of the criteria.
• <output_file>: Path to the output CSV file to save the results.

Example

topsis data.csv "0.2,0.1,0.3,0.15,0.15,0.1" "+,-,+,+,-,+" results.csv

This command will process the data.csv file using the specified weights and impacts and output the results to results.csv.

NOTE

• Ensure that the input file has at least three columns: one for alternatives and at least two for criteria.
• All criteria columns should contain numeric values.
• The number of weights and impacts must match the number of criteria.
• Impacts should only be '+' or '-'.
