水力鋼構造物の寿命予測エキスパート・システムとその適用

抄録

Aiming to establish the life term prediction method of existing hydropower steel structures, various techniques which reported previously, such as simplified data aquisition, structural analysis program, data base, and expert system, were investigated.
The purpose of this paper is to describe the configuration and knowledge bases of the expert system in detail, and to show the application results of the system to radial gates of 25 sites. Especially, effectiveness of AHP (Analytic Hierarchy Process) Method to determine the weights among ambiguous qualitative data, such as appearance, operational condition, environment and others, is emphasized, and essential diagnosis rules for the expert system of existing structures are pointed out.
