Abstract |
|
|
| One of the most important issues in data envelopment analysis is sensitivity analysis of efficient and inefficient decision
making units (DMUs). Sensitivity analysis of inefficient units has been more studied recently. We know that a specific inefficient
DMUcan scarcely reach to the efficient frontier and achieving the score 1 in efficiency but it can easily obtain an efficiency score of
a (a is a constant which is usually closed to 1 and defined by the decision maker). In this paper we are going to find a region which
named Improvement Region (IR) for a specific inefficient DMU which can obtain at least an efficiency score of a. In this region the
inefficient DMU which is under evaluation can satisfy the decision maker and also it can be improved itself to gain a new efficiency
score and by these variations it is made more contented for decision maker. The procedure is illustrated by numerical examples. |
