Fault diagnosis knowledge tree ranking device, and fault diagnosis knowledge tree ranking manner

摘要

PROBLEM TO BE SOLVED: To efficiently genereate a more optimized fault diagnostic knowledge tree to be effectively used for fault diagnosis while suppressing operator's load. SOLUTION: A fault diagnostic knowledge tree hierarchization setting device 42 divides a large fault diagnostic knowledge tree having much knowledge into small fault diagnostic knowledge trees having small quantity of knowledge and relationally links these divided trees to hierarchiz them. A fault diagnostic knowledge tree hierarchization display device 36 displays these hierarchizated knowledge trees. Each acquired knowledge is hierarchized and optimized.
