Abstract
The development of an expert system for selection of pile type for design of a pile foundation is documented. The expert system, pile selection version 1.0 (Ps1), incorporates many unique features. Among them are approximate reasoning with fuzzy logic, the blackboard architecture, and the emulated parallel processing of fuzzy production rules. An example using ps1 for pile selection is presented, and possible enhancement of the system is discussed.
