Efficiency Evaluation of Food and Beverage Companies in Thailand : An Application of Relational Two-Stage Data Envelopment Analysis

摘要

This study used a relational two-stage data envelopment analysis (DEA) to evaluate the efficiency of 23 food and beverage companies in Thailand in 2011. The whole production process of the companies can be divided into two sub-processes for analyzing the efficiency differences: production achievement and profit generation. The conclusion shows that the low efficiency score of the profit generation process leads to the low overall efficiency score of the companies.
