The arrival of the mobile phone and its rapid and widespread growth
may well be seen as one of the most significant developments in the fields of
communication and information technology over the past two decades. The aim
of this study is to compare two hybrid multi-criteria decision-making (MCDM)
approaches to evaluate the mobile phone options with respect to user’s
preferences. Firstly, we identify the most desirable features influencing the
choice of a mobile phone. This is realised through a survey conducted among
the target group, the experiences of the telecommunication sector experts and
the studies in the literature. Secondly, two MCDM methods are used in the
evaluation procedure. More precisely, two hybrid methods ‘analytic hierarchy
process–voting analytic hierarchy process (AHP–VAHP) and AHP-entropy–
technique for order preference by similarity to ideal solution (TOPSIS)’ are
compared in ranking the mobile phone alternatives. A case study is made at a
telecommunication centre in Iran to investigate both techniques. Considering
the same ranking of the two methods, the numerical results are evaluated using
data envelopment analysis to identify the most beneficial method.
