Network data envelopment analysis with two-level maximin strategy

Network data envelopment analysis (NDEA), one of the most important branches recent DEA developments, has been developed for examining decision making units (DMUs) a system with complex and internal component divisions. In this study we apply maximin strategy to network at two levels. At individual DMU level, evaluate system’s performance by maximizing minimum divisions efficiencies, which is based on weak-link approach. all DMUs DMUs’ ratio efficiency model. With such two-level strategy, propose NDEA model efficiencies as well same time. The will provide unique unbiased scores in improve incomparable weak discrimination power traditional models. addition, discuss cross evaluation proposed models are applied supply chains illustrations.
