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.
