An MOLP method for Complex-valued DEA model

Data Envelopment Analysis(DEA) is a mathematical programming technique for evaluating decision making units(DMUs) with multiple inputs and outputs. In all standard DEA models semi positive real- valued measures are assumed, while in some real cases inputs and outputs may take complex valued. The question is related to measuring efficiency in such cases. As far as we are aware, there is not any special formulation replying the complex-valuedquestions. In this study Multi-Objective Linear Programming(MOLP) model has been proposed in the literature to takethe complex-valued efficiency into consideration and demonstrate the applicability of the method in complex-valued situations
