Make-or-buy decision using interval-valued intuitionistic fuzzy COPRAS method

Abstract

One of the central issues in strategic management is the determination of a firm’s vertical boundaries. Since almost all the publications in the literature are based on crisp measurements and evaluations for make-or-buy decisions, we proposed a multi attribute decision making method using interval-valued intuitionistic fuzzy COPRAS for make-or-buy decision assessment. An illustrative example is presented for a Turkish toy company.
