Evaluating the Comparative Productivities of the Bakeries by Using the Data Envelopment Analysis : A research in West Mediterranean Region

The performance evaluation of the enterprises is an important element of their strategic and routine decisions. In performance evaluation instruments such as stability, productivity, effecitiveness and efficiency can be used. Concepts such as efficiency and productivity are and will always be important in our country in which sources are limited. Competition, in our day, forces enterprises to use the sources efficiently. Enterprises need some measurements to define their variances from targeted plans and to decide whether their competitors are beter or worse than themselseves. Different techniques can be used for measuring productivity of an enterprise. One of the techniques that are prominent nowadays is Data Envelopment Analyze (DEA). DEA is a method that was desipned to measure the relative productivities of economical organizations or enterprises which are responsible for changing input to ouput and based on linear programming principles. In our study using the DEA technique, cost of the investment, maintaince, staff, fixed cost as input parameter , sale quantity and sale amount as an output parameter are took into consideration in the calculation of productivity of an enterprise on bread . In this study, 115 bakeries -which operate in West Mediterranean Region-, are evaluated using Data Envelopment Analysis techniques. Reference enterprises has been determined as a result of productivity scores of analyse. Low productivity level-enterprises have been observed after comparing other enterprises with reference enterprises.
