ABSTRACT
Food and agricultural production in Thailand play an indispensable role in economic growth. The frozen vegetable industry is considered to be important due to its increasing annual exports. The goal of this paper is to measure the efficiency of export frozen vegetables using network DEA. We use the two-stage model to measures efficiency by separating the supply chain structure into suppliers and manufacturers. There are 12 criteria used for inputs and outputs. The results show that out of 8 organizations with supply chains, only 2 chains are efficient according to the BCC-O model and only 1 chain is efficient under the CCR-O model. However, if the manufacturer’s role in the supply chain is considered, the results show that the majority of these manufacturers are efficient.
