Sensitive analysis of the directional distance function

This paper analyses the directional distance function at presence of uncontrollable and undesirable factors. By focusing on the undesirable, uncontrollable and environmental factors, the effect of these factors are surveyed. The Directional Distance Function (DDF) model is imposed to deal with each of these factors simultaneously and separately. Then the efficiency of a chemical reaction of a sample is assessed according to each scenario. The data is derived from laboratory dataset. Different DDF models through various inputs and outputs specifications are used while considering temperature levels as an environmental factor.
