# kt-toposis

kt-toposis is a Python package for displaying ranking of all criteria using Topsis technique to get good computational efficiency and ability to measure the relative performance for each alternative in a simple mathematical form.

## Topsis Description

Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) is one of the multi-criteria models in making decision which is known for its simplicity, rationality, comprehensibility and good computational efficiency. Multi-criteria decision making (MCDM) refers to making choice of the best alternative from among a finite set of decision alternatives in terms of multiple, usually conflicting criteria.

## Getting Started

These instructions will help you to install and use this package for general use.

## Prerequisites

Your csv file should not have categorical data

## Installation

Use the package manager pip to install foobar.

pip install kt-toposis


## Usage

You can import it either in Python IDLE or run directly through command prompt

### For Command Prompt

If you want to use this package on "data.csv" file with 4 columns. You need to change the directory where "data.csv" is stored then. Here -w represents weights which signifies weight of each feature or column in our dataset and -i represents impacts which signifies impact of each column or feature in our data. If a feature is good we will use + to denote else we will use -

kt-toposis data.csv -w 1 1 1 1 -i + + - +


You can use the following command for help

kt-toposis -h


### For Python IDLE

from kt_toposis.topsis import top
top(X,weights,impacts)

#X should be a matrix
#impacts should be a list of string + for positive impact - for negative impact
#weights should be a list of int or float


### Sample dataset

Singer ID Sur Taal Laaye Pitch Pace
S1 0.79 0.62 1.25 60.89 11
S2 0.66 0.44 2.89 3.07 20
S3 0.56 0.31 1.57 62.87 16
S4 0.82 0.67 2.68 70.19 16
S5 0.75 0.56 1.3 80.39 20
kt-toposis Book1.csv -w 1 1 1 1 1 -i + + + + +


### Result
