FAULT TREE SIMPLIFYING APPARATUS AND FAULT TREE ANALYZING METHOD

摘要

A fault tree simplification apparatus according to an embodiment of the present invention includes a search unit for searching for a cyclic structure that is a logical structure in which a plurality of gates having the same input and output are circulated in a faulty tree, And a conversion unit for converting the simplifiable structure into a simplified structure, when the at least one of the simplified structures is included in the cyclic structure.
