Ageneralizationofthelinguisticaggregationfunctions(oroperators)ispresentedbyusinggeneralizedandquasiarithmeticmeans.Firstly,thelinguisticweightedgeneralizedmean(LWGM)andthelinguisticgeneralizedorderedweightedaveraging(LGOWA)operatorareintroduced.Theseaggregationfunctionsuselinguisticinformationandgeneralizedmeansintheweightedaverage(WA)andintheorderedweightedaveraging(OWA)function.Theyareveryusefulforuncertainsituationswheretheavailableinformationcannotbeassessedwithnumericalvaluesbutitispossibletouselinguisticassessments.Theseaggregationoperatorsgeneralizeawiderangeofaggregationoperatorsthatuselinguisticinformationsuchasthelinguisticgeneralizedmean(LGM),thelinguisticOWA(LOWA)operatorandthelinguisticorderedweightedquadraticaveraging(LOWQA)operator.Wealsointroduceafurthergeneralizationbyusingquasi-arithmeticmeansinsteadofgeneralizedmeansobtainingthequasi-LWAandthequasi-LOWAoperator.Finally,wedevelopanapplicationofthenewapproachwhereweanalyzeadecisionmakingproblemregardingtheselectionofstrategies.
