Ranking software quality factors using intuitionistic preference relations and group decision making

It is well known that developers and professionals do not agree on common factors that derive quality of software. Therefore it is appropriate to apply group decision taking to rank quality factors of software. The present research considers three decision takers, viz., users, developers and professionals to decide ranking of quality factors. In this process, each decision maker provides his/her intuitionistic fuzzy preference values rather than exact values for each factor. These preference values are aggregated using averaging operator, which is further aggregated using weighted arithmetic averaging operator. Finally eight considered factors are ranked.
