Design and Diagnosis Problem Solving with Multifunctional Technical Knowledge Bases

“…Xplain was probably the fist syu&~m to pro-89 I vide explanations of problem-solving knowledge by showing how it was obtained by compilation from other knowledge about the domain (26,35]. Our work on functional representations (FR) (31] is similar in showing how to compile diagnostic programs from functional representations of mechanical devices.…”
