Discussion On 'prediction Of Ground Vibrations Resulting From The Blasting Operations In An Open-pit Mine By Adaptive Neuro-fuzzy Inference System'

摘要

The discusser appreciates the exhaustive study undertaken by the authors for predicting ground vibrations resulting from the blasting operations in an open-pit mine by adaptive neuro-fuzzy inference system. However, the present paper has some scientific mistakes especially in the basic conception and application of the fuzzy theory. The straightforward application of ANFIS through software gives rise to physical and logical problems even though the results may seem convenient from the numerical tests point of view. In any scientific research the first steps should include the logical and physical principles of the data at hand in addition to its simple treatment through some graphs such as the scatter diagrams prior to classical regression or ANFIS methodology application. Otherwise, complete dependence on any methodology especially by software without knowing its internal domain may lead to erroneous scientific applications. The paper by the authors suffers from such defects even though it seems numerically sound. The following logical points may be raised on the scientific grounds.
