A Step by Step Method to Improve the Performance of Decision Making Units

In this paper, we present the concept of context-dependentdea based on the fdh model by introducing the fdh-attractivenessand fdh-progress for each dmu. by the presented method, not onlywe can improve the performance of inefficient dmus, but we can finda target for improvement among the existing efficient dmus. thesetargets are observed dmus and are not some virtual points on theefficiency frontier. also, the paper presents a step by step method toimprove the performance of dmus by measuring fdh-attractivenessand fdh-progress. one numerical example and a case study consistsof 20 iranian bank branches are given for illustration.
