摘要：
In this paper, the relationship between possibility sets, a fuzzy number concept, and efficiency score in Data Envelopment Analysis (DEA) is dealt with. A new DEA model for handling crisp data using fuzzy concept is proposed. The model which is equivalent to a traditional DEA model is then extended to incorporate situations whereby some inputs, in a fuzzy sense, are almost discretionary variables. With this relationship, a new perspective of viewing and exploring other DEA models is now made possible. (C) 2015 Elsevier Ltd. All rights reserved.
