Conventional software quality models such as ISO 9126 address quality in terms of factors. Since distinct quality factors have dissimilar units, comprehensive quality cant be computed just by adding them. But, a mechanism to determine quality is needed to guide developers in achieving the desired product quality. This research proposes evolution levels of stakeholders trust namely a priori belief, indirect trust, proximity trust, transitive trust and intentional trust which are used to quantify quality of Multi-agent system. Since trust is subjective in nature and Intuitionistic fuzzy sets are most suited for capturing subjectiveness, these have been adopted to evaluate multi level measure of stakeholders trust.]]>Atanassov, K.,1999Barber, K.S. and J.
