Abstract: As follow up effort, the present research takes advantage of the concreting productivity database as established by Lu and Anson (2004), and in particular, applies an ANN based sensitivity analysis technique to process the productivity data for the concreting operations using the stationary pump and reveal quantitative information on the significance of independent input factors. Definition of the partial derivative based sensitivity measure for a trained ANN model is distinguished for continuous, discrete, and binary variables respectively in order to factor in the effect on the model's sensitivity of the unit of measure and the relevant range of input factors of various natures, which could be considerably different in practical engineering applications. It is found that dropping the least sensitive factor identified from NN modeling brings about slight tradeoff of the prediction accuracy, while the sensitivity of the other independent factors remains relatively stable.
