In recent years there has been an exponential growth in the number of publications related
to theory and applications of Data Envelopment Analysis (DEA). Charnes, Cooper, and …

This paper deals with inverse DEA from both theoretical and applied viewpoints. First, some
methodological approaches and theoretical results are outlined; and then an application of …

This paper deals with the estimation of returns to scale (RTS) in free disposal hull (FDH)
models and provides some stability intervals for preserving the RTS classification. It has …

Recently, in some papers in the field of operations research the performance analysis of
decision making units, in the presence of time factor, has been dealt with by an analytical …

A concept that has sparked considerable interest in DEA is that of returns to scale (RTS).
One of the basic and useful definitions of RTS in DEA models is based upon the PPS. In this …

This paper provides computationally efficient approaches for determining to which returns to
scale (RTS) class a unit belongs in weight-restricted Data Envelopment Analysis (DEA) …

Abstract Global Returns to Scale (GRS) is an important notion in performance analysis
under Free Disposal Hull (FDH) technologies. Ray Average Productivity (RAP) function has …

Scale elasticity (SE) and returns to scale (RTS) are important topics in performance analysis,
which help managers to make decisions about the expansion or contraction of the operation …

In this paper some new results about two important topics in performance analysis, including
scale elasticity (SE) and returns to scale (RTS), in the presence of weight restrictions and …

In many countries, including Iran, Provincial Departments of Physical Education try to
develop the athletic sports and sports for all in their related areas (state), using the …
