In this paper a new model is introduced to evaluate decision making units (DMUs) in the production possibility set (PPS), with three properties. (a) The observed activities ( x j , y j ) , ( j = 1 , … , n ) belong to PPS. (b) Any convex combination of activities in PPS belongs to PPS. (c) PPS is the smallest set that satisfying the principles (a) and (b). Thus, a model is presented to investigate convex efficient DMU. Then, the efficiency of each DMU would be measured by presenting a criterion to assess efficiency. Finally, a discussion regarding to return to scale would be presented following an example to explain accuracy of the presented discussion.
