Abstract
In this paper, we propose two stage fuzzy DEA models with undesirable outputs to evaluate banking system. The banking system is divided to two subsystems: production stage and profit stage. In the model, two kinds of assumptions (constant returns to scale and variable returns to scale) are considered, and fuzzy parameters are adopted to describe the uncertain factors. Chance constrained operator is used to handle the proposed model and equivalent transformations are given to make the models solvable. We illustrate and validate the proposed models by evaluating 16 Chinese commercial banks. Some discussions are also presented to show the differences and advantages of the models.
