Hierarchical probabilistic model generation system, hierarchical probability model generation method, and program

摘要

A hierarchical probability model generation system includes: an independent event analysis unit that specifies independent events about operating conditions of a system on the basis of availability requirements of the system and configuration information of the system, the independent events being calculable independently of each other; an event tree generation unit that generates an event tree using the independent events; and a state transition model generation unit that generates state transition models used to calculate occurrence probabilities of the independent events.
