In addition, there are some interrelations between ISO 9126 quality factors that must be considered during assessment. In this study, we present a Fuzzy Group Analytical Network Process (FGANP) model for evaluating software packages in which some dependencies between criteria are considered. This ANP model is based on the criteria and sub-criteria which were introduced by previous researchers. Also, interrelations between the factors are considered from their suggestions. Therefore, for deriving preference ratio among decision makers and to reach a global argument among them, we use Group Fuzzy Preference Programming (GFPP). Finally, we show the general assessment techniques and some obtained results using our model to evaluate the three existing E-learning software which are employed in some universities.]]>Jadhav, A.S. and R.M.
