| Abstract: | In this paper we suggest a new approach to representing the empirical production possibility set with its facet hyperplanes. Extending the work of reference 3, this paper also indicates a general algorithm to calculate the gradient of DEA efficiency for inefficient DMUs within the empirical production set, in which all inputs and outputs of the inefficient DMUs are simultaneously changed to make them efficient DMUs. Two wrong conclusions existing in references 4 and 7 respectively are discovered. |
