Algorithm for calculating a gradual improvement target and its applications in DEA
*Syuuji Yamada (Niigata University)
In this paper, we introduce a model called the RBM model that DMU is evaluated by both
score and best ranking. In the RBM model, we can find a weight which maximize its efficiency score
keeping the best ranking. Based on the best ranking, we define a ranking frontier given by expanding
the efficient frontier. Moreover, we propose an algorithm to calculate an improvement target for each
inefficient DMU by utilizing the ranking frontier.
