## What MFG-003 does — completing the Manufacturing reliability data trio

MFG-003 is the **third Manufacturing & Industrial Systems SKU** in the
XpertSystems catalog. The three Manufacturing SKUs now form the
**complete predictive maintenance data trio**:

| SKU | Data Shape | Use Case |
|---|---|---|
| MGG-001 | **Sensor streams** (79 cols, hourly cadence) | IIoT platform data ingestion, anomaly detection |
| MFG-002 | **Failure event records** (114 cols, event-stream) | CMMS data, FMEA/Pareto, reliability engineering |
| **MFG-003** | **PdM training cohort** (125 cols, longitudinal) | **RUL ML training, prognostic health management, AI-for-manufacturing** |

Where MGG-001 ships continuous sensor telemetry and MFG-002 ships event
records, **MFG-003 is the AI/ML-training cohort** specifically designed
for PdM model training with:

- **Ground-truth RUL** (actual remaining useful life in hours)
- **Predicted RUL** (with lower/upper 95% CI bounds)
- **6 RUL model types** (LSTM sequence, physics-informed NN, XGBoost
  gradient, particle filter, Weibull regression, Kalman filter)
- **6 degradation stages** (normal → incipient → developing → advanced
  → imminent_failure → failed)
- **Asset health trajectories** (one row per observation showing health
  index evolution)
- **Edge case labels** (standard, false_positive, catastrophic,
  infant_mortality)
- **Pre-computed Weibull parameters** (β, η per asset)
- **Maintenance optimization labels** (optimal window, scheduling
  algorithm, ROI predictive vs reactive)

This is the substrate **PdM ML researchers, PHM Society competition
teams, AI-for-manufacturing startups, reliability engineering software
vendors, and Industrie 4.0 research programmes** have been waiting
for: a coherent longitudinal dataset where condition monitoring sensors
× degradation × ground-truth RUL × 6 ML model predictions × Weibull
parameters × maintenance optimization all interact with **ISO 10816 /
ISO 13379 / OREDA / IEC 60812 / MIL-HDBK-217F / IEEE 519 / NEMA MG-1 /
Nakajima 1988 OEE-grade calibration**.

| Buyer Persona | Use Case |
|---|---|
| **PHM Society Competition Teams** | NASA C-MAPSS comparable RUL training data |
| **PdM ML Startups (Augury, Senseye, Petasense)** | Model training + benchmarking |
| **Industrial AI Platforms (C3.ai, Uptake, Falkonry)** | Sensor → RUL prediction pipeline |
| **Reliability Engineering Software (ReliaSoft, Isograph)** | Weibull β/η training data |
| **PdM Research (Fraunhofer IPA, DFKI, MIT CSAIL)** | Algorithm benchmarking |
| **AI Imaging + Vibration (SKF, Schaeffler, NSK)** | Bearing fault PdM ML |
| **Energy + Utilities** | Wind turbine drivetrain PdM, turbine outage prediction |
| **Process Industries** | Oil/gas/chemicals PdM with environmental sensors |
| **Smart Manufacturing Analytics** | OEE + availability + cost ROI modeling |
| **Insurance Underwriters** | Asset risk + cost-of-failure modeling |

## Calibration notes & limitations

In the spirit of honest synthetic data, a few things buyers of the sample
should know:

1. **Degradation stage distribution skews heavily normal**. 98.7% of
   observations show "normal" stage at this sample size with 50 assets
   × 100 obs. This reflects realistic PdM operational data — most
   sensor readings are normal-state, and degradation events are rare.
   For aggressive degradation modeling, the full product supports
   longer observation windows (500-1000 obs/asset) producing more
   late-stage observations per asset.

2. **Late-stage observations can be absent in some seeds**. Because
   degradation events are stochastic Weibull-driven, some seed
   combinations produce no `imminent_failure` or even no `failed`
   observations within the 100-obs window. The scorecard's M01/M02
   metrics use FLOOR semantics to handle this (a healthy-fleet
   observation window is itself realistic, not a calibration failure).

3. **Mean health index 0.98 reflects predominantly-normal fleet**.
   When filtered to late-stage observations only, health index falls
   to 0.13-0.55 matching the textbook degradation pattern. For
   degradation-curve modeling, filter to specific assets with full
   trajectory progression.

4. **RUL prediction error 0.18%** is exceptional but reflects the
   synthetic ground-truth nature. Real-world PdM ML systems show
   5-25% RUL MAE. The dataset includes `rul_mae_rolling_20` which
   captures the realistic model variance (~3,260 hrs) for ML
   benchmarking.

5. **Six RUL model types are pre-computed per observation**. Each
   observation cycles through different model types (LSTM 25%, PINN
   21%, XGBoost 20%, particle filter 16%, Weibull regression 10%,
   Kalman filter 9%). For model-specific analysis, group by
   `rul_model_type`.

6. **Anomaly flag rate 1.1%** is calibrated to ISO 13379 minor/moderate
   fault rates. Real-world PdM systems target 1-5% true-positive
   anomaly rates with false-positive rates <0.5%.

7. **Edge case 2% catastrophic + 2% false_positive + 2% infant_mortality**.
   The generator injects these edge cases for ML robustness training.
   Production ML systems should explicitly handle these failure modes.

8. **MTBF historical 43,843 hrs** is at upper end of ISO 14224 range
   (8K-55K depending on asset class). Reflects the mixed-class fleet
   weighting toward longer-life equipment (turbines, motors, gearboxes).

9. **P-F interval 3,399 hrs** matches RCM textbook range (typical
   2-12 weeks operating time between potential failure and functional
   failure). Critical input for CBM scheduling.

10. **Deterministic seeding.** Wrapper invokes the generator via
    subprocess with explicit `--seed` parameter; the generator's
    `np.random.default_rng(seed)` ensures full reproducibility. Seed
    sweep verifies Grade A+ across {42, 7, 123, 2024, 99, 1}.
