This research proposes an integrated benchmarking framework illustrated in the context of a large supply chain system comparised of 102 distribution centers. (DCs). We employ recent extentions of data envelopment analysis while addressing difficulties often associated with empirical data in real life settings. The study measures DC productivity in a large scale setting, evaluates and identifies DCs with consistent best performanceusing facet analysis, and detects performance trends using window analysis of 4 years'data.
