| 内容記述 | We extend the concept of returns to scale in Data Envelopment Analysis (DEA) to the weight restriction environments. By the addition of weight restrictions, the status of returns to scale, i.e., increasing, constant and decreasing may suffer a change. We first define "returns to scale" under weight restrictions and propose a method for identifying the status of returns to scale. Then, it is demonstrated that the region of the most productive scale size (MPSS) will usually be narrowed by this addition. For an inefficient decision making unit (DMU), a simple rule for determining the status of returns to scale of its projected DMU will be presented. An empirical study compares the results of the proposed method with those of the BCC model and demonstrates the change in the MPSS for both models. | |||||||
