Abstract :
The treatment of uncertainty in expert system shells is addressed, starting with a review of the modeling of uncertainty by expert system shells. An experiment to replicate earlier work investigating the manner in which individuals manipulate certainty factors in comparison to commercial shells is discussed. Comparisons are made among seven commercial shells, both personal-computer (PC)-based and mainframe-based, and individuals. A significant difference between individuals and shells themselves is indicated. Some implications for both expert system and decision-support-system methodologies are discussed.<>
