Characteristics and structures of weak efficient surfaces of production possibility sets

摘要: This paper studies the characteristics and structure of weak surface production possibility set. We apply techniques methods transferring a polyhedral cone from its intersection form to sum form, identify an representation give theorem set, which includes three complementary slackness conditions. define input efficiency output for different DEA models according form. It investigates surfaces, proves theorems efficiency. The establish weighted combination inputs outputs that are efficient. Numerical examples provided illustration.
