Abstract:

On the basis of slacks-based measure (SBM) model, firstly, divide the inputs, desirable outputs and undesirable outputs into separable and non-separable variables, build the undesirable SBM efficiency evaluation model based on non-separable variables to the complex production system. This model is more suitable to the actual production process of the production system. Then, on the basis of total regulation target of undesirable outputs, build the non-separable variables undesirable SBM model according to the perspective of regulation of undesirable outputs, this model measures the impact of regulation of undesirable outputs on the efficiency of the whole system. Finally, take 0.5 as the step length, use an example to test the sensitivity of its impact.
