Yes, but only with qualification and local validation. A scrap pattern model trained in one plant or program is rarely portable without adjustment.
The main reason is that scrap behavior is usually influenced by local conditions: machine configuration, tooling wear, routing differences, material lots, inspection methods, operator practices, shift patterns, rework rules, and how nonconformance data is coded. Even when two plants make the same part family, the data-generating process may not be equivalent.
If those differences are not addressed, the model may still produce scores, but the predictions can be misleading. In practice, that means false alarms, missed scrap drivers, poor trust from operations, and decisions based on patterns that do not hold in the target environment.
Feature engineering logic, such as how you derive setup-to-run transitions, lot-level context, environmental windows, or machine state sequences.
Modeling approach, such as classification versus anomaly detection, if the target process has similar failure mechanisms and enough labeled history.
Data pipelines, governance patterns, and review workflows for traceability, approvals, and change control.
Shared failure taxonomies, but only if defect and scrap codes are actually standardized across sites.
Model thresholds and alert logic.
Importance rankings for input variables.
Direct interpretation of defect classes when local coding practices differ.
Performance claims from one plant to another.
Reuse is most defensible when the source and target share most of the following:
Comparable product families, materials, tolerances, and process steps
Similar equipment types, maintenance condition, and control logic
Consistent definitions for scrap, rework, concession, and yield loss
Stable routings and work instruction governance
Enough target-site history to test drift and recalibrate the model
Reliable integration between MES, ERP, QMS, historian, and machine data sources
If those conditions are weak, you are not really reusing a model. You are reusing a starting point.
In most regulated manufacturing environments, the practical path is not a global model pushed unchanged to every site. It is a controlled template approach:
Standardize core data definitions where possible.
Map local tags, event codes, routing identifiers, and defect codes.
Retrain or fine-tune using target-site data.
Validate performance locally against known scrap events.
Run in parallel before using outputs for operational decisions.
Version the model, inputs, thresholds, and approval history.
That is slower than copying one model everywhere, but it is usually more credible and more sustainable.
Full replacement of existing MES, QMS, or data collection systems just to make model reuse easier is often a poor strategy in long-lifecycle regulated operations. The qualification burden, validation effort, downtime risk, integration complexity, and traceability impact are usually higher than the benefit. Coexistence with existing systems is more common, which means portability depends heavily on integration quality and data normalization.
A single enterprise model gives more standardization, but it can hide local failure modes.
Plant-specific models are often more accurate, but they are harder to govern at scale.
Transfer learning can reduce development time, but only if target data is sufficient and representative.
Tighter standardization improves reuse, but may require process and coding changes that plants resist or cannot absorb quickly.
So the short answer is: yes, sometimes, but not as an assumption and not without evidence. Reuse should be treated as a controlled transfer with local validation, not as proof that one plant’s scrap behavior generalizes to another.
