Performance measurement of power plants in the existence of weight restrictions via slacks-based model

Purpose: The purpose of this paper is to suggest a model for evaluating the best power plants in the presence of weight restrictions. Design/methodology/approach: The paper introduces a model, which is based on slacks-based model (SBM) (one of the data envelopment analysis (DEA) models). Findings: The paper depicts the power plant evaluation process through a DEA model, while allowing for the incorporation of preferences of decision maker (DM). The chief advantage of the proposed model is that it does not demand exact weights from the DM. Originality/value: To the best of the author's knowledge, there is not any reference that evaluates power plants by means of SBM in the presence of weight restrictions.
