While data science has the power to revolutionize the reliability industry, it will only do so with strong guidance from SMEs. This combination enables facilities to develop solutions to challenges based on each method’s unique strengths.
This study found that a machine learning model was able to predict degradation rates for a hydrocracker unit more accurately and with a smaller margin of error compared to current industry practices.
This article is Part 2 in a series discussing condition monitoring optimization where statistical inference techniques on the measured data can be utilized to provide reasonable expectations regarding the true extent of damage on the asset.
Condition monitoring optimization goes beyond traditional CML optimization, which is often limited in the breadth of analysis, or can overemphasize a subset of the overall objective.
Facilities that can successfully leverage both their data and expertise while effectively integrating this unified model into their core business processes can improve performance and eliminate non-value-added activities.
