Abstract

fetched live from OpenAlex

The reliability indices of the turbines were analyzed based on a six-year failure database. Such reliability indices as failure rate (), repair rate () and mean time to repair () have been estimated. The analyses showed that gas turbine 1 (GT1) has maximum failure rate () of once in 100 h in 2007 with system availability () of 0.333 and minimum failure rate () of once in 1000 h in 2005 with of 0.983. While for gas turbine 2 (GT2), of once 100 h was obtained in 2007 with of 0.333 and  of once in 1000 h in 2008 with of 0.0869. It was also showed that GT1 has a maximum repair rate () of once in 1.45 h in 2005 with of 0.983 and minimum repair rate () of once in 21.28 h in 2006 with  of 0.513. In the other hand, GT2 has  of once in 1.44 h in 2008 with of 0.869 and of once in 35.7 h in 2006 with of 0.513. GT1 has maximum mean time to repair () of 2133 h in 2006 with of 0.595 and minimum mean time to repair () of 72.5 h in 2005 with of 0.714. Similarly, GT2 has  of 3552 h in 2006 with of 0.595 and  of 144 h in 2008 with  of 0.984. For the period under study, GT1 has  of 0.333 in the year 2007 and  of 0.983 in 2005 while GT2 has of 0.595 in 2006 and  of 0.984 in 2008. Measures to improve the reliability () indices of the plant have been suggested such as training and retraining of technical personnel on the major equipment being used.   Key words: Warri Refining and Petrochemical Company (WRPC) gas turbines, reliability indices, maintainability.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
