摘要

A Data Envelopment Analysis (DEA) algorithm is considered as a signal processor, receiving DEA inputs and outputs and computing efficiency index as an output signal. This approach allows us to represent the DEA-algorithm as a DEA-neuron, and to include it into a neural network (NN). The combination of DEA with NN has advantages over conventional DEA in problems where different types of efficiencies, e.g. related to different periods of time or types of activity, are considered together. Suggested approach is applied to analysis of daily stock prices. Numerical example is given.
