HIERARCHICAL PROBABILITY MODEL GENERATION SYSTEM, HIERARCHICAL PROBABILITY MODEL GENERATION METHOD, AND PROGRAM |
摘要 |
A hierarchical probability model capable of improving the performance and reliability of an availability analysis in a large and complex system is efficiently generated.;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. |

1. A hierarchical probability model generation system, comprising:
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. |
