DEA 모형을 이용한 우유 대리점의 효율성 분석

Abstract

DEA model is developed for evaluating the relative efficiencies of the dairy product agencies. The efficiencies are calculated from the agency's and the producer’s points of view. The input and output components are determined based on the cost and benefit factors, respectively. From the producer’s point of view, the outstanding amount, total number of households, financial aids from the producer, and distance from the plant to the agent are determined as input components. Also, the outputs are total sales and rate of sales increase. As such, the input and output components from the agency’s point of view are also determined. Data from the 355 agencies are gathered and the relative efficiencies are evaluated using the input and output model, respectively. As a result, the efficiency of each agency is evaluated and the projection to the efficient agency is suggested for the inefficient agency to be effective. Also, each agency is classified into four groups depending on the cost and efficiency, such as LE(less productive and efficient) and HI(high productive and inefficient) groups. Moreover, the non-parametric analyses are performed to test the hypotheses that the efficiencies between two groups are the same depending on the ages of the agent, total number of households, and number of family accounts.
