Abstract
The existing Data Envelopment Analysis models for evaluating the relative eciency of a set of decision making units by using various inputs to produce various outputs are limited to crisp data in crisp production possi- bility set. In this paper, rst of all the production possibility set is extended to the fuzzy production possibility set by extension principle in constant re- turn to scale, and then the fuzzy model of Charnes, Cooper and Rhodes in input oriented is proposed so that it satises the initial concepts with crisp data. Finally, the fuzzy model of Charnes, Cooper and Rhodes for evaluating decision making units is illustrated by solving two numerical examples.
