Abstract

The term of productivity and the term of efficiency, two important indicators of performance, are used interchangeably in daily life, although in reality the meanings they have are different from each other. The term of productivity refers to the proportional relationship between output and inputs. In literature, the term of efficiency is rather used to describe in a way that gives the possibility to benchmark Decision Makin Units performance with each other relatively. Several analysis methods have been developed for the measurement of the efficiency. These methods are Parametric Measurement Methods, Non-parametric Measurement Methods and Ratio Analysis. Data Envelopment Analysis is a Linear Programming-based Non-parametric Approach, which aims to measure efficiencies of DMUs in multi-input and multi-output environments. Data Envelopment Analysis was offered to analyze the efficiencies of the entities under the assumption of constant returns to scale by Charles et al, in 1978.
