electre-1-3-python-app

This is the Python application that I created doing my thesis studying Industrial Engineering and Management in Democritus University of Thrace. It contains all the files as long as a download link to the standalone executable.

Installation

This application is for windows only.

Easy method

If you have a bit of space in your local pc, the easiest way is to download the executable (.exe) from here.

There are 2 alternatives, one is windowed mode, OptimizeIt.exe, - no console at all - and the second is a consoled version, OptimizeIt_db.exe, - there is still the window and the console additionally - for bebugging reasons.

Then, jsut download the folder "content" and place it in the same folder as the executable.

That's it! Now you can run it normally, by double clicking the executable.

Second method

This method is done by cloning the repo in your local machine.

Requres a Python installation to your pc, preferably Python v3.10.10 which was the version that this application was developed at. It is also required to have Git installed.

First, open the terminal and navigate to the folder you want to install the application.

Then, clone the repo, runing:

git clone https://github.com/nikosbeskos/electre-1-3-python-app

When the download is complete, it is recomended to create a Python virtual environment so that there is a clean Python installation for the application:

python -m venv <your-venv-name>

Then you can activate the venv using:

<your-venv-name>\Scripts\Activate.ps1

and deactivate it using:

deactivate

For running the app, it is recomended to be in an active Python venv. Then, it is needed to install the requred Python libraries, so run:

pip install -r requirements.txt

That's it! now you can run the application. To run it, use an IDE or a debuger to run the main.py or run in the terminal:

python main.py

Usage

Since it has a GUI developed, usege is easy and self explanatory.

If you have selected to install it via the first method, just double click the executable and you re on.

If you selected to install it via the second method, you can use an IDE of your choice to navigate to the installation folder and run main.py . Another way to run it, is through the terminal. navigate to the installation folder, and run:

python main.py

The way it works, is by using an excel spreadsheet that has a particular form, like this:

Important

The requirements of the excel spreadsheet are:

It has to be of the filetype "<filename>.xlsx" .
The application will only read from the first sheet of the file, if it has multiple sheets.
The sheet must be empty, and only contain the data of the MCDA decision problem's Decision Matrix, i.e. names of the criteria, names of the alternatives and their values for each criterion.
Data must be in a matrix where the fisrt column is the column of the alternatives's names, and the first row is the row of the criteria names, just like it is shown in the green and blue marked area in the image above. The rest of the cells are filled with the values of the decision problem.
First cell of the matrix CANNOT be empty. it doesnt matter what value it has.
Two samples of how should the excel file be are here for ELECTRE I, and here for ELECTRE III.

Contributing

This code was developed for my Diploma thesis of my master's degree in Industrial Engineering and Management of the Engineering Department of Democritus University of Thrace, located in Xanthi, Greece. Any furhter commenting or help regarding the application and its evolution would be much appreciated and considered positively.
