Topsis-Jasween-102017187 0.2

Topsis-Jasween-102017187 is a Python library to solve Multiple Criteria Decision Making(MCDM) problems by using TOPSIS

TOPSIS

Goals of this project :

:star: Learn about mathematics of TOPSIS Algorithm
:star: Implementation of TOPSIS Algorithm using python. The code for same is available in 102017187.py file
:star: Create a package and publish it on (https://pypi.org/). Also, provide a user manual for it.
:star: Test the package by installing it and run it through command line.
:star: Create a web app for TOPSIS

What is TOPSIS ?

• Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) is a multi-criteria-based decision-making method
• {Eg. You want to purchase a mobile phone. But you are confused because there are so many factors like price, memory, battery, camera quality etc. So, TOPSIS provides you the solution.}
• It is a way to allocate the ranks on basis of the weights and impact of the given factors.

How to install this package ?

pip install Topsis-Jasween-102017187

---

Example of how to use it on command line:

Usages: topsis <InputDataFile> <Weights> <Impacts> <ResultFileName>

Parameters:

Arguments	Description
InputDataFile	Input CSV file path
Weights	Comma separated numbers
Impacts	Comma separated either '+' or '-'
ResultFileName	Output CSV file path

It accepts input file (which contains parameters and their values in csv format) and weights and impacts.

It creates a output file(.csv), that contains the original data with Topsis Score and Ranks.

Be careful about these, otherwise you will get an error :smile: :

• Correct no. of parameters must be provided in command line
• Input file must be in csv format and must be present
• Input file must contain three or more columns
• Input file: first column is the object/variable name (e.g. M1, M2, M3, M4…...)
• Input file: from 2nd to last column the valuse should be only numeric
• Result file should be .csv file
• Weights and impacts should be in correct format and separated by ","
• Number of weights, number of impacts and number of columns (from 2nd to last columns) must be same.
• Impacts must be either +ve or -ve
