Unformatted text preview: ge is stored in a rulebased format. Two kinds of problemsolving rules Symptomatic Topographic Two schematic components A stored pattern of information relating to a given problem situation A set of motor programs appropriate for governing the corrective action(s) Human error
Human error Symptom rules or Srules Rapid & relatively effortless in retrieval & application
Require a match between local cues and situational components of the stored rule. Human error
Human error Topographic rules or Trules Do not need any reference to specific system components
They demand access to some mental or actual map of the system & a consideration of the structural & functional relationships to its constituent parts. Human error
Human error Fuzzy set theory Criteria for rule selection The rule must be recallable (available) The rule must be applicable to the current situation (applicable)
The rule must have some expected utility (useful)
The rule must be simple (easy) Human error
Human error Fuzzy set theory 1. Criteria are not always distinguishable from a human problemsolving perspective
2. Each rule must be evaluated according to the possibility of its membership in the fuzzy sets of available, applicable, useful, and simple rules.
3. Rule selection is heav...
