    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (512 KB)

    A quadratic bilevel programming problem is transformed into a single level complementarity slackness problem by applying Karush-Kuhn-Tucker (KKT) conditions. To cope with the complementarity constraints, a binary encoding scheme is adopted for KKT multipliers, and then the complementarity slackness problem is simplified to successive quadratic programming problems, which can be solved by many algo...

  • Integrating dual-role variables in data envelopment analysis

    Publication Year: 2010, Page(s):771 - 776
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (568 KB)

    Traditional data envelopment analysis (DEA) theory assumes that decision variables are regarded as inputs or outputs, and no variable can play the roles of both an input and an output at the same time. In fact, there exist some variables that work as inputs and outputs simultaneously and are called dual-role variables. Traditional DEA models cannot be used to appraise the performance of decision m... View full abstract»
