Technical and Scale Efficiencies of Milk Collection Centers in Thailand
Jakrapan Suksawat and Winai Puttakul
This study measured the technical and scale efficiencies of 42 milk collection centers, performing as cooperatives, in order to improve their operational efficiencies. The analysis was based on data of the years 2001and 2002; and used data envelopment analysis (DEA) technique formulated as CRR and BCC models. Four inputs and three outputs formed a set of variables. The results show that the average values of the technical efficiency index, the operational efficiency index, and the scale efficiency index are very close, i.e. 0.980 0.989 and 0.989, respectively. There were 16 centers found inefficient. Reducing the input use by 3-24 % and increasing the output by 0-38% would improve their efficiencies.
