Relationship between the allocated Fuzzy cost and dea efficiency

R. Shahverdi, F. Rezai Balf, P. Nasrollahian. Islamic Azad University


In this paper we propose an approach for compute performance of a decision making unit (DMU) in allocation fuzzy cost. If cost is not precisely defined, so we could consider it as fuzzy number, and if each DMU has other cost inputs then fuzzy cost must be combine with other cost measures. Based on this observation, this paper investigated about relationship between allocated fuzzy cost and efficiency in DEA. To illustrate the method, numerical results for an example from the literature are presented.
