Description¶

FAULT is the article's context-specific fault diagnosis simulation, named because "an excellent acronym was FAULT which stands for Framework for Aiding the Understanding of Logical Troubleshooting." Subjects receive general symptoms, then gather information by checking gauges, requesting component function definitions, making observations, or bench-testing removed components, and can replace parts. Costs for observations, tests, and replacements plus a priori failure probabilities yield a single cost performance measure; subjects minimize total cost. Its software is general, with systems specified by data files, and has been used for automobile and aircraft powerplant systems.

Design Implications¶

Context¶

Requirements¶

• Particular systems of interest are completely specified by data files rather than software changes.

Constraints¶

• Thus far the article reports use concentrated on various automobile and aircraft systems, in particular powerplant systems.

Target Learners¶

• maintenance trainees in FAA certificate programs

Target Learning Goals¶

• context-specific equipment fault diagnosis under cost constraints

Claims¶

Related Elements¶

• CRESST Integrated Assessment System: a computer-based suite of performance assessment tasks

Examples¶

• Rate only poor tests in rule-based aiding: full quality ratings were counterproductive
