Fault tree displaying method and process diagnosis support system

摘要

In a system which performs an inference based on fault tree knowledge, a guidance and a formula of definition can be displayed in a window on a CRT display screen by selecting the individual items from a fault tree on the display screen by using, for example, a soft key. For displaying an abnormal course in one display screen, only events relevant to the abnormal course is picked up, and the fault tree is then reedited, so that the reedited fault tree can be automatically displayed on the display screen.
