While these charts show the usefulness of a well-operated TUM, there are a few considerations to take into account when dealing with any TUM.
The Great Debate – “I want my MTVBF.“
Most miners and process operators have opinions on how metrics are viewed and calculated. There is much focus on the numbers and how “time” events are categorized and reported. Outliers Mining Solutions focuses on simplifying and clearly defining the time categories to create ease and make more accurate data capture. The simplified process looks like: applying standard formulae to the data, analyze, and make decisions based on the trends more than the number itself. With good data, individual numbers are explainable, whether good or bad.
The strength of a well-designed model resides in its ability to host simple, yet effective single-use time codes aligned with one category to minimize confusion and post-processing. Arbitrary time constraints such as “Reason code X > 12 hours” and “Reason X code <12 hours”, which map in different categories but that are also for the same root cause, create challenges in implementation and use, and require judgment, post-processing, and reconciliation afterward.
Simplicity goes a long way – the people selecting these codes often don’t have time to contemplate them in real-time; hence simple non-duplicate codes yield a better result in adoption and data quality.
Classification of time use plays a huge factor in determining the site’s time usage. For example, the GMG TUM classifies “No Production” under “Unscheduled Time,” so any increase has no impact on availability metrics. Outliers Mining Solutions recognizes that mining is capital intensive, so operations must maximize usage to deliver the required products and return on investment. Thus, the Outliers Mining Solutions TUM includes “No Production” within the primary category of Available (AT). An increase or decrease in “No Production” impacts availability metrics directly, which tends to ensure the requisite focus to minimize “No Production” whenever possible.
