Reduced Multivariate Polynomial Model for Manufacturing Costs Estimation of Piping Elements

الملخص EN

This paper discusses the development and evaluation of an estimation model of manufacturing costs of piping elements through the application of a Reduced Multivariate Polynomial (RMP).

The model allows obtaining accurate estimations, even when enough and adequate information is not available.

This situation typically occurs in the early stages of the design process of industrial products.

The experimental evaluations show that the approach is capable, with a low complexity, of reducing uncertainties and to predict costs with significant precision.

Comparisons with a neural network showed also that the RMP performs better considering a set of classical performance measures with the corresponding lower complexity and higher accuracy.
