Evaluarea calitatii si competitivitatii produselorEtapa I:
Definirea multimii caracteristicilor produselor1. Caracteristici
tehnico-functionale:- dimensiuni : cote de gabarit : lungime(L),
latime(l), Grosime (g), Greutate(m), Marime ecran (in),- de
exploatare:Rata de contrast(rc), Memorie interna (mi), OS (os),
3G(3g), Bluetooth(b), Camera(c), Video(v), Standby 2G(s2g), Standby
3G(s3g), Conv. 2G(c2g), Conv. 3G(c3g), Calitate audio(ca), Difuzor
voce(dv), Difuzor zgomot(dz), Difuzor sunet(ds), SAR(sar).2.
Economice:- pret(p)Caracteristicile ce apartin lui S1: rc, mi, os,
3g,b, c, v, s2g, s3g, c2g, c3g, ca, dv, dsCaracteristicile ce
apartin lui S2: L,l,in,sar,g, m, p,dz.
Etapa II: Determinarea coeficientilor de importanta a
caracteristicilor asupra nivelului tehnic absolutCalculelese vor
face prin utilizarea procentului de comparare reciproca a doua cate
doua caracteristici: metodologia STEM.Pentru determinarea tabelului
2, caracteristicile au fost grupate pe 4 grade de importanta.Grupa
