Estimation of efficiency and infinitesimals in data envelopment analysis
Summary: The role of the non-Archimedean construct \(\varepsilon\) in the DEA models is clarified. It is established that the multiplier (envelopment) forms of DEA models can be infeasible (unbounded). Sufficient conditions are established for feasibility (boundedness) of multiplier (envelopment) forms of DEA models and a method of securing a global assurance interval for \(\varepsilon\) is provided.
