  The existing software requirement selection methods have mainly focused on
optimizing the economic value of a software product while ignoring its social
values and their long-term impacts on the society. Social values however, are
also important and need to be taken into account in software requirement
selection. Moreover, social values of software requirements may change in the
presence or absence of other requirements due to the value dependencies among
those requirements. These dependencies are imprecise and hard to specify in
software projects. This paper presents an Integer Programming (IP) model for
the integration of social values and dependencies among them into software
requirement selection. We further, account for the imprecision of social values
and dependencies among them using the algebraic structure of fuzzy graphs.
