Current DEA includes two models, CCR and BCC, with different scale assumption.The former compares to all DMU but the later compares DMU with comparable condition. These two models can be explored under two operation targets, input or output oriented. The input oriented target is about how to reduce input when output remained fixed and output oriented target is about how to create maximum output based on current available resources. For this study, it is aimed at creating the most highquality (satisfied) service cases with minimum resources input. Therefore, output oriented model is used for analysis.
