BFX: OPERATIONAL EXPERT SYSTEM FOR BRIDGE FABRICATION

The Bridge Fabrication Error Solution Expert System (BFX) was developed to help designers and inspectors determine the severity of fabrication errors on steel bridge members and specify the necessary repairs. Aspects of the development, delivery, and operation of BFX of direct interest to highway bridge and materials engineers are described. The scope of BFX focused on tolerance, drilling and punching, cutting, and lamination fabrication errors that do not have a codified repair procedure. During predelivery testing, BFX provided the correct repair in two-thirds of the test cases, recognized that the test case was not covered by its rule base in one-third of the test cases, and gave the wrong solution for none of the test cases. BFX has been in use at the Kansas Department of Transportation since January 1994. An operational example using BFX is presented.
