Promethee 1.0

Promethee algorithm

Promethee

Multi-decision criteria algorithm Promethee

Usage:

install with pip:

pip install Promethee==1.0

Import on your code:

from Promethee import promethee

Paramethers:

promethee(df,pesos,objetivos,tipo,q,p)

df = pandas dataframe with de Criterias, the problems and their values as the example:
|__|C1|C2|C3|
|D1| 6 | 7 |10|
|D2| 9 | 8 | 9 |
|D3| 8 | 2 | 8 |
|D4| 7 | 8 | 5 |
|D5| 1 |10|10|
|D6| 8 | 3 | 8 |
|D7| 6 |10| 9 |
|D8| 1 | 2 | 6 |

pesos = list with the respective wheights of each criteria
objetivos = list with the respectives values if the criteria is for maximization or minimization. True = minimization False = maximization
tipo = int that determines the type of the function used:

1. Usual Criterion
   
2. U-shape Criterion
   
3. V-shape Criterion
   
4. Level Criterion
   
5. V-Shape with indiference criterion
   
6. Gaussion Criterion
   

q and p = int that is necessarie in some types of function, if not informed, their default value is 0 (functions type 4 and 5 requires 'q' and 'p', in that case, 'q' is the intermediary value and 'p' is the higher value).
