ABSTRACT
It is often useful to incorporate a metamodel into the sensitivity analysis of the economics of capital projects. While statistical models are straightforward and understandable, they are not always appropriate, especially where there are discontinuities or complex relationships in the economic data. This paper puts forth a neural network approach that uses design of experiments to generate metamodel training and validation data from the projects) under consideration. Both backpropagation multi-layered perceptron networks and cascade correlation networks are explored and compared with the statistical approach. It is shown that the backpropagation networks work well for a variety ...
