Beschreibung
Zusammenfassung:	A system operation decision-making assistance device includes: a state mode clustering unit that calculates, on the basis of measurement data DB1 of a power system and a clustering parameter DB3, which state mode, from among prescribed state modes, applies to a power system; a state mode collation unit that collates state transition data DB4 indicating transitions between state modes and the calculated state mode to calculate state transition probability data, which is the probability of transitioning from the calculated state mode to each state mode defined in the state transition data; and an accident shift pattern calculation unit that calculates important accident cases on the basis of a system model DB2, an importance parameter DB5 including the importance of a power system accident, the measurement data, and the calculated state transition probability data.
