Shift Performance Variation Analyzer
Surface output gaps between comparable shifts and lines
Reference implementation. Industrial use requires validation on plant-specific data. Metrics are from open evaluation splits, not customer plants.
Intended use
Finding output gaps between comparable shifts, crews, and lines under similar conditions, where the best-versus-typical gap is often recoverable.
Inputs & outputs
Inputs
Output by shift and crew, comparable-line records, conditions
Output
Comparable-conditions performance gaps with context
Training data & evaluation
Training-data classification
Synthetic shift/crew output panels with matched conditions.
Evaluation approach
Ranking AUC for comparable-conditions gaps on a held-out split.
AUC 0.86· open split
Industrial relevance
Applies across Metals, Chemicals, FMCG / CPG, Paper · Glass · Cement, Battery Materials. The value is highest where the affected asset is a constraint and additional output can be monetized.
Limitations
- Comparability hinges on capturing the conditions that matter.
- Highlights gaps; it does not diagnose the practice behind them.
