Topsis_iyasha_102103034

Topsis_iyasha_102103034 is a Python library for dealing with Multiple Criteria Decision Making (MCDM) problems by applying Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS).

Installation

Install Topsis_iyasha_102103034 using Pypi via pip.

$ pip install topsis_iyasha_102103034

Usage

You can use this package in python as :

from topsis_iyasha_102103034 import topsis
inputFile="sample.csv"
weights="1,1,1,1"
impacts="-,+,+,+"
resultFile="result.csv" 
topsis(inputFile, weights, impacts, resultFile)

OR

You can use this package via commandline as :

$ topsis [InputDataFile as .csv] [Weights as a string] [Impacts as a string] [ResultFileName as .csv]

For Example :

$ topsis sample.csv "1,1,1,1" "-,+,+,+" result.csv

Please Note That :

• The first column and first row are removed by the library before processing, in attempt to remove indices and headers. So the csv MUST follow the format as shown in sample.csv shown in the Example section.
• The input data file MUST contain three or more columns.
• The second to last columns of the data file MUST contain NUMERIC values.
• The number of weights, impacts and columns (second to last) MUST be SAME.
• Impacts MUST either be '+' or '-'.
• Impacts and Weights MUST be separated by ‘,’ (comma).

Example

sample.csv

A csv file that contains data for mobile models and their features.

Model	Price (in $)	Storage Space (in GB)	Camera (in MP)	Looks (1 to 5)
M1	250	16	12	5
M2	200	16	8	3
M3	300	32	16	4
M4	275	32	8	4
M5	225	16	16	2

Weights : 0.25,0.25,0.25,0.25

Impacts : -,+,+,+

input :

$ topsis sample.csv "0.25,0.25,0.25,0.25" "-,+,+,+" result.csv

result.csv

A csv file that contains the same data as sample.csv with two additional columns 'Topsis Score' and 'Rank'.

Model	Price (in $)	Storage Space (in GB)	Camera (in MP)	Looks (1 to 5)	Topsis Score	Rank
M1	250	16	12	5	53.43	3
M2	200	16	8	3	30.84	5
M3	300	32	16	4	69.16	1
