Abstract
Maintenance optimisation is indispensable to the core business objectives of industries that utilises physical assets. A quantitative maintenance optimisation technique known as the Modelling System Failures (MSF) is critically reviewed to identify its relevance to industries that employs physical assets. Practical application of the approach to optimise the maintenance activities of wind turbines is explored and discussed in a case study. The analysis is based maximum likelihood parameter estimation in the Weibull distribution. Shape and scale parameters for a gearbox and its components are estimated. The estimated parameters are used to design Reliability Block Diagrams to model the failures of the gearbox of a selected wind turbine. The models are simulated using Monte Carlo simulation software to assess the reliability, availability and maintainability of the gearbox, and the resultant effects on the wind turbine operation. The methodology presented in the paper is sufficiently generic to any mechanical system in the Built Environment/Construction Industry.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
