Evaluation and selection of Medical Tourism sites: A rough AHP based
  MABAC approach
  In this paper, a novel multiple criteria decision making (MCDM) methodology
is presented for assessing and prioritizing medical tourism destinations in
uncertain environment. A systematic evaluation and assessment method is
proposed by integrating rough number based AHP (Analytic Hierarchy Process) and
rough number based MABAC (Multi-Attributive Border Approximation area
Comparison). Rough number is used to aggregate individual judgments and
preferences to deal with vagueness in decision making due to limited data.
Rough AHP analyzes the relative importance of criteria based on their
preferences given by experts. Rough MABAC evaluates the alternative sites based
on the criteria weights. The proposed methodology is explained through a case
study considering different cities for healthcare service in India. The
validity of the obtained ranking for the given decision making problem is
established by testing criteria proposed by Wang and Triantaphyllou (2008)
along with further analysis and discussion.
