Abstract :

Measuring the performance of a production system is an important task in management for purposesof control, planning, etc.Lord Kelvin said, “When you can measure what you are speaking about, andexpress it in numbers, you know something about it; but when you cannot measure it, when youcannot express it in numbers, your knowledge is of a meager and unsatisfactory kind.”Hence, management knowledge is a measurable science; if we can’t measure each subject, then wecan’t control then, and management is impossible. We know that the major criterion of performance isproductivity, and we should be able to measure it. Data Envelopment Analysis (DEA) can estimatesystematically the relative efficiencies of an organization. The efficiency of a organization can bebenchmarked using DEA. DEA presents a model for evaluating the performance of a set ofcomparable decision making units (DMUs). In this paper, we develop a new model for calculatingproductivity with data envelopment analysis.
