5 CONCLUSIONS
This paper presented a methodology to analyse maintenance data sets form a broad range of computerised maintenance
management systems. The purposes of these analyses are to identify strengths and weaknesses in the maintenance management
system and opportunities for improvements. The developed methodology to perform failure modes and effect analysis was
described. Easy to use and yet powerful software have been developed to facilitate FMEA. It captures work orders from the
CMMS and allocates selected work to defined failure modes. It also specifies which equipment is affected by a selected failure
mode, what is the total cost of the work and what is the total amount of labour hours spent on work in this mode. Weibull
analysis is also used to test the shape factors and MTTF of the various failure modes. The results from various case studies,
showing outcomes from FMEA and Weibull analysis and wide range of reports, which can be provided from analysing the
computerised maintenance management system data sets were presented.
