Thus,?given?a?set?of?alternatives?(options)?and?a?number of?decision?criteria,?the?purpose of?MCDM?is?to?provide?a?choice,?ranking,? description,? classification,? sorting,? and,? in? most? instances,? an? order? of? alternatives,?from?the?most?preferred?to?the?least?favored option. (Mulliner? et?al.,?2016).?Assigning?weights?to?criteria?is?a?crucial?step?that?needs?to?be? reconsidered?in?the?majority?of?MCDM?models.?However,?one?of?the?main? issues? with? MCDM? is? figuring? out? how? to? weight? the? various? criteria? (Pamu?ar et?al.? 2018;?Vinogradova et? al.,? 2018).?The? assessment? of?the? criteria? weights? can? be subjective,? objective? or? hybrid (Ginevi?ius and Podvezko,?2005).?The?subjective?methods?calculate?weights?in?accordance? with?the? preferences? of? decision?makers? for?the? criteria.?The? opinion? or? intuition? of? the? decision? maker? is? reflected? in? weights? created? using? subjective?methods.?Due?to?lack?of?information?or?experience,?the?decision? maker?may?impact?the?findings?of?analyses?or?the?rankings?of?alternatives? based? on? weights (Ma? et? al.,? 1999).? Furthermore,? determining? the? subjective weights for?the?criteria takes?a?lot? of?time,? particularly?when? there?is? disagreement? among?the? decision?makers? regarding?the?issue? at? hand? (Odu,? 2019). On? the? contrary, the? objective? methods? calculate? weights?on?the?basis?of?objective?data?(e.g.?decision?matrix).?However,?by? using? mathematical? models? to? generate? weights,? objective? methods? frequently? ignore? the? decision? maker's? subjective? judgment (Ma? et? al.,? 1999). The?question?of?how?completely?and?objectively?the?small?sample? of?alternative?traits?conveys?the?value?of?the?criteria?is?also?left?unanswered? for? these? methodologies.? Obviously,? the? decision matrix? entirely? determines? the? outcome (Mukhametzyanov,? 2021).
