Popis: Maintenance Management Support Systems (MMSSs) for nuclear power plants have been developed using component aging estimation methods and decision tree analysis for maintenance planning. The former evaluates actual component reliability through statistical analysis on field maintenance data. The latter provides preventive maintenance (PM) planning guidance using heuristic expert knowledge and estimated reliability parameters. The following aspects have been investigated: 1. A systematic and effective method of managing components/parts design information and field maintenance data 2. A method for estimating component aging based on a statistical analysis of field maintenance data 3. A method for providing PM planning guidance using estimated component reliability/performance parameters and decision tree analysis. Based on these investigations, two MMSSs were developed. One deals with “general maintenance data”, which are common to all component types and are amenable to common data handling. The other syst...
