Interval Cross Efficiency Measurement for General Two-Stage Systems

The data envelopment analysis (DEA), which is based on mathematical programming, employed to measure the relative efficiency of several homogeneous decision-making units (DMUs) with multiple inputs and outputs. There has been extensive research developing classical DEA models for various forms conditions. For example, ranking such as cross have proposed address shortcomings initial basic models. network systems developed (NDEA), interval (IDEA) provided take into account uncertainty. But using this technique issues that all these conditions requires a single model, in are included. In case study paper, branches banking industry ranked, presented according different approaches NDEA order calculate general two-stage system. Finally, results compared.
