Application of artificial neural network on risk evaluation of engineering project investment

This paper seeks to some drawbacks of the conventional risk analysis methods and engineering project risk evaluation methods; and proposes a new method, which applies the artificial neural network (ANN) to engineering project risk evaluation. Based on the established risk evaluation index system, an ANN model that can redeem the deficiencies of the other methods is built. And finally, the effectiveness of the proposed model is demonstrated by an example. Simulation results show that this model does not need to define the weights and has been proved satisfactory.
