1. A gasket connection reliability evaluation system comprising:
a measurement value acquisition unit configured to acquire a measurement value obtained through measurement by a sensor provided in a system including piping connections with gaskets;
a simulation unit configured to simulate a behavior of a fluid flowing through the system on the basis of the measurement value and calculate a state quantity relating to the fluid;
a loading analysis unit configured to analyze a loading applied to each of the gaskets on the basis of the measurement value and the state quantity and calculate a connection index of the gasket;
a fatigue analysis unit configured to analyze a fatigue state of the gasket on the basis of the measurement value, the state quantity, the loading applied to the gasket, and a specifications and condition of the gasket connection and calculate a deterioration index of the gasket; and
a reliability evaluation unit configured to calculate a reliability of the gasket on the basis of the measurement value, the state quantity, the connection index, the deterioration index, and a predetermined reliability evaluation model.
