Dependence of multi‐criteria evaluation result on choice of preference functions and their parameters

Abstract

A considerable usage increase of multicriteria methods is recently observed in the area of quantitative analysis of social or economical phenomena. The PROMETHEE methods are discerned from other multi‐criteria methods by depth of their intrinsic logic and by using preference functions, which make up a foundation of the methods. Shapes of functions and their parameters are chosen by decision‐makers thus exerting clear advantages and features of the methods. This paper reveals influence of the choice of preference functions and their parameters on the outcome of evaluation. Along with already recently described by the authors PROMETHEE I method the other PROMETHEE II method is described and examples of its application are provided. New types of preference functions were proposed.

Santrauka

Pastaruoju metu socialiniu ir ekonominiu sudetingu reiškiniu kiekybiniam lyginimui plačiai taikomi daugiakriteriniai metodai. PROMETHEE metodai skiriasi nuo kitu daugiakriteriniu metodu savo ypatumu ir gilesne logika. Metodo pagrinda sudaro vadinamosios prioritetu funkcijos. Ju tipai pasirenkami ir ju parametrai nustatomi aktyviai dalyvaujant priimantiems sprendima asmenims. Tai yra PROMETHEE metodu privalumas bei ypatumas. Darbe parodyta vertinimu rezultatu priklausomybe nuo prioritetu funkciju ir ju parametru reikšmiu pasirinkimo. Kartu su autoriu anksčiau nagrinetu PROMETHEE I metodu šiame darbe aprašytas PROMETHEE II metodas, pateiktas jo taikymo pavyzdys ranguojant alternatyvas.
