The method of generating the weight data may take into account the degree of corrosion in the historical data, the weights of different environmental factors, material characteristics, etc. These weight data are generated using mathematical models, expert evaluation, or data mining techniques.

Specifically, corrosion rate: the corrosion rates of different parts are different, and the parts with higher corrosion rates can obtain higher weight. Depth of corrosion: the depth of corrosion may be used to indicate the extent of corrosion, with greater depths of corrosion resulting in higher weights. Material properties: the material properties of the piers, such as corrosion resistance, strength, etc., can also influence the weight calculation.
