Performance assessment of a spare part dealer network using data envelopment analysis

Abstract

In this study, we analyze comparative dealer efficiency of a spare part distributor, using data envelopment analysis. In order to ensure homogeneity in the data sets, five different clusters are formed, and for each cluster, BCC-Output and CCR-Output oriented models are applied. The results of all models are interpreted and the comparison of the results is provided. The comparison is made in two perspectives: One perspective is related with different clusters of the same data set under the same data envelopment analysis model. The other perspective compares different types of the efficient frontiers under two different data envelopment analysis models. The results provide insight about the nature of Data Envelopment Analysis as well as about the practical problem at hand.
