A risk-based maintenance system was developed fbr cost-effective maintenance ef steam turbines.This system was consisted of field maintenance database and probabilistic risk analysis algorithm.The probabilistic risk analysis procedure has several steps as fo11ows; (1) Development ofparts trees to be resolved into the smallest maintenance units, (2) Construction of event trees of failure, damage or deterioration for individual parts, (3)
