Abstract
In the previous paper of this series, the analysis using descriptive statistics and the Weibull distribution on hospital facilities were shown. This report deals with quantitative tendencies of maintenace and major maintenance results. Firstly by using the logarithmic normal distribution for quantitative analysis of maintenance, we assume and estimate the time to repair based on these results and qualitative analysis results. This is very useful in carrying out scheduled maintenance plan. Secondly we discuss on the major maintenance which is being defined, as that requiring more than 360.0man・min to repair a machinery/system. According to this proposal and actual verification, we are contributing in suggesting to treat upon the major maintenance.
