The library is also fully integrated withchatGPT, elevating result interpretation through AI. Additionally, pyDecision provides the flexibility to import results from custom methods or those not yet implemented in the library for swift comparison.UsageInstallpipinstallpyDecisionImport# Import AHPfrompyDecision.algorithmimportahp_method# Parametersweight_derivation='geometric'# 'mean' or 'geometric'# Datasetdataset=np.array([#g1     g2     g3     g4     g5     g6     g7[1,1/3,1/5,1,1/4,1/2,3],#g1[3,1,1/2,2,1/3,3,3],#g2[5,2,1,4,5,6,5],#g3[1,1/2,1/4,1,1/4,1,2],#g4[4,3,1/5,4,1,3,2],#g5[2,1/3,1/6,1,1/3,1,1/3],#g6[1/3,1/3,1/5,1/2,1/2,3,1]#g7])# Call AHP Functionweights,rc=ahp_method(dataset,wd=weight_derivation)# Weigthsforiinrange(0,weights.shape[0]):print('w(g'+str(i+1)+'): ',round(weights[i],3))# Consistency Ratioprint('RC: '+str(round(rc,2)))if(rc>0.10):print('The solution is inconsistent, the pairwise comparisons must be reviewed')else:print('The solution is consistent')Try it inColab:AHP (Colab Demo) (Paper)Fuzzy AHP (Colab Demo) (Paper)ARAS (Colab Demo) (Paper)Fuzzy ARAS (Colab Demo) (Paper)Borda (Colab Demo) (Paper)BWM (Colab Demo) (Paper)Simplified BWM (Colab Demo) (Paper)Fuzzy BWM (Colab Demo) (Paper)CILOS (Colab Demo) (Paper)CoCoSo (Colab Demo) (Paper)CODAS (Colab Demo) (Paper)Copeland (Colab Demo) (Paper)COPRAS (Colab Demo) (Paper)Fuzzy COPRAS (Colab Demo) (Paper)CRADIS (Colab Demo) (Paper)CRITIC (Colab Demo) (Paper)DEMATEL (Colab Demo) (Paper)Fuzzy DEMATEL (Colab Demo) (Paper)EDAS (Colab Demo) (Paper)Fuzzy EDAS (Colab Demo) (Paper)Entropy (Colab Demo) (Paper)ELECTRE I     (Colab Demo) (Paper)ELECTRE I_s   (Colab Demo) (Paper)ELECTRE I_v   (Colab Demo) (Paper)ELECTRE II    (Colab Demo) (Paper)ELECTRE III   (Colab Demo) (Paper)ELECTRE IV    (Colab Demo) (Paper)ELECTRE Tri-B (Colab Demo) (Paper)GRA (Colab Demo) (Paper)IDOCRIW (Colab Demo) (Paper)MABAC (Colab Demo) (Paper)MACBETH (Colab Demo) (Paper)MAIRCA (Colab Demo) (Paper)MARCOS (Colab Demo) (Paper)MAUT (Colab Demo) (Paper)MEREC (Colab Demo) (Paper)MOORA (Colab Demo) (Paper)Fuzzy MOORA (Colab Demo) (Paper)MOOSRA (Colab Demo) (Paper)MULTIMOORA (Colab Demo) (Paper)OCRA (Colab Demo) (Paper)Fuzzy OCRA (Colab Demo) (Paper)ORESTE (Colab Demo) (Paper)PIV (Colab Demo) (Paper)PROMETHEE I    (Colab Demo) (Paper)PROMETHEE II   (Colab Demo) (Paper)PROMETHEE III  (Colab Demo) (Paper)PROMETHEE IV   (Colab Demo) (Paper)PROMETHEE V    (Colab Demo) (Paper)PROMETHEE VI   (Colab Demo) (Paper)PROMETHEE Gaia (Colab Demo) (Paper)EC PROMETHEE (Colab Demo) (Paper)PSI (Colab Demo) (Paper)Regime (Colab Demo) (Paper)ROV (Colab Demo) (Paper)SAW (Colab Demo) (Paper)SMART (Colab Demo) (Paper)SPOTIS (Colab Demo) (Paper)TODIM (Colab Demo) (Paper)TOPSIS (Colab Demo) (Paper)Fuzzy TOPSIS (Colab Demo) (Paper)VIKOR (Colab Demo) (Paper)Fuzzy VIKOR (Colab Demo) (Paper)WINGS (Colab Demo) (Paper)WSM, WPM, WASPAS (Colab Demo) (Paper)Fuzzy WSM, Fuzzy WPM, Fuzzy WASPAS (Colab Demo) (Paper)Compare Methods:Compare Ranks & Ask chatGPT (Colab Demo)Compare Fuzzy Ranks & Ask chatGPT (Colab Demo)Compare Weigths & Ask chatGPT (Colab Demo)Advanced MCDA Methods:3MOAHP- Inconsistency Reduction Technique for AHP and Fuzzy-AHP MethodspyMissingAHP- A Method to Infer AHP Missing Pairwise ComparisonsELECTRE-Tree- Algorithm to infer the ELECTRE Tri-B method parametersRanking-Trees- Algorithm to infer the ELECTRE II, III, IV, and PROMETHEE I, II, III, IV method parametersAcknowledgementThis section is dedicated to all the people who helped to improve or correct the code.
