VIKOR-based group decision-making method for software quality assessment

Software quality is an important research direction in software engineering domain,  which is a multi- dimen-sional evaluation problem.  The VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR) technique is a comprehensive  method for handing the multi-dimensional evaluation problems. The projection is commonly used to measure the closeness between two decision objects in decision science.  However, two research questions are found in this work: (1) There is no specific concrete regret  matrix in current VIKOR technique; (2) The existing projection measures are not  always reasonable in interval-valued intuitionistic fuzzy setting. Two research gaps are filled  systematically in this paper: (1) A specific concrete regret matrix is provided in this extended VIKOR-based group decision-making method; (2) A new normalized projection measure is provided in order to measure the closeness between two decision matrices.  The decision procedures are also provided in this paper. A practical application to  the software quality assessment is introduced.  Some experimental comparisons are provided in order to illustrate the feasibility and practicability of introduced method.
