Finding defining hyperplanes and efficient surfaces Of the PPS in the DEA

Data envelopment analysis (DEA) is a mathematical programming technique for evaluating efficiency of homogeneous decision making units (DMUs) with multiple inputs and multiple outputs. The production possibility set (PPS) is defined as the set of all inputs and outputs implicitly use PPS to evaluate relative efficiency of DMUs. In this paper, we propose an applicable algorithm for finding all defining hyperplanes and identify strong efficient surfaces of the PPS.
