DEA Based Total Efficiency Evaluation Method Using the Dissatisfaction Index

抄録

DEA is a nonparametric method for finding the relative efficiency of DMUs (Decision Making Units). However, the most of these studies is based on the situation that objective DMU has competed with other DMUs as a group of relative comparison. There is a little study from the analyst aspect that manages the all DMUs which are in the state of cooperation. This paper proposed the DEA based method in order to control the activities when all DMU are in the state of cooperation. Proposed method has constructed following three steps: (1) employee's temporary assignment based on DEA evaluation and analyses of inconsistent characteristics, (2) setting of dissatisfaction degrees for each employees based on inconsistent characteristics, (3) employee's assignment based on each dissatisfaction degrees. Numerical study shows that the proposed method can control the activities of DMUs according to analyst's intention.
