Fuzzy Network Data Envelopment Analysis: A Possibility Approach

The main purpose of this paper is to present a new approach for performance measurement of network data envelopment analysis (NDEA) with two-stage structure in the presence of imprecise and vague data. Possibilistic programming is one of the popular and applicable methods that can be used to reach this goal. By applying of possibility measure and chance constrained programming (CCP), the possibilistic network data envelopment analysis (PNDEA) model for different return to scale (RTS) is proposed. Finally, the fuzzy network DEA model that presented in this study is used for efficiency measurement of investment companies (ICs) with two-stage processes contain of operational management process and portfolio management process. Illustrative results show that proposed model is effective
