Design and Construction of the Spirit Lake Outlet Tunnel, Mount St. Helens, Washington
In 1982, a governmental task force was formed to evaluate the hazard posed by the blockage of Spirit Lake that resulted from the eruption of Mount St. Helens in May 1980. An analysis was...
What is an Expert System
Knowledge-based expert systems (KBES) have created much excitement in the civil engineering computer user community. KBES evoke expectations of full-blown Artificial Intelligence (AI)...
Problem Solving Using Expert System Techniques
There are basically two approaches to problem solving currently used in expert systems: the derivation approach and the formation approach. The derivation approach involves deriving a...
Expert System Tools for Civil Engineering Applications
Expert system software tools have played a major role in expediting program development. Some problems should not and possibly cannot be solved by current expert system technology. For...
Attributes and Characteristics of Expert Systems
This paper discusses some of the characteristics of expert systems, with emphasis on the incorporation of these attributes in the development stage. It is suggested that the scope of expert...
Expert Systems in an Engineering-Construction Firm
