FAULT TREE SIMPLIFYING APPARATUS FAULT TREE ANALYZING APPARATUS AND FAULT TREE ANALYZING METHOD

摘要

A fault tree simplifying apparatus according to an embodiment of the present invention may include a search part which searches for a loop structure that is a logical structure where a plurality of gates are circulated in a fault tree, a confirmation part which confirms whether or not a simplifiable structure where the output value of a first gate among the plurality of gates is unchanged when at least one of the input values of a second gate is a predetermined value is included in the loop structure, and a conversion part which converts the simplifiable structure into the simplified structure. It is possible to reduce time required for the analysis of the fault tree.
