## What MGG-001 does — and how it opens a new XpertSystems vertical

MGG-001 is the **first Manufacturing & Industrial Systems SKU** in the
XpertSystems catalog, complementing our existing Oil & Gas vertical (17
SKUs) and Healthcare/Neurology vertical (10 SKUs). Where Oil & Gas
targets upstream/midstream operators and Healthcare targets pharma R&D,
**Manufacturing targets a different industrial buyer category**:
discrete manufacturers, plant maintenance teams, industrial IoT
platforms, and the AI-for-manufacturing ecosystem.

| Vertical | SKUs | Primary Audience |
|---|---|---|
| Oil & Gas | 17 | Upstream/midstream operators, ISO 14224 / API 689 / OREDA users |
| Healthcare/Neurology | 10 | Pharma R&D, clinical trial design, biomarker validation |
| **Manufacturing** | **1+ (this is MGG-001)** | **Plant maintenance, MES/CMMS vendors, AI-for-manufacturing, Industrie 4.0** |

The dataset captures **physics-based, temporally correlated** sensor
streams from 8 industrial equipment types covering the full Industrial
IoT (IIoT) sensor stack: temperature, vibration (with ISO 10816 zone
classification + bearing fault frequencies BPFO/BPFI/BSF/FTF),
pressure, flow, electrical (3-phase + power quality), process,
oil/lubricant, and health/RUL indicators.

| Buyer Persona | Use Case |
|---|---|
| Predictive Maintenance Platform | Sensor fusion + anomaly detection ML |
| CMMS / EAM Vendors | Failure mode + maintenance recommendation ML |
| Industrial IoT Platforms | Multi-protocol (MQTT/OPC-UA/Modbus) data modeling |
| Industrie 4.0 Researchers | Digital twin training data |
| Vibration Analysis Specialists | ISO 10816 zone classification + BPFO/BPFI ML |
| Motor Current Signature Analysis | MCSA sideband + broken rotor bar detection |
| RUL Prediction Researchers | Weibull-degradation + sensor trajectory ML |
| Bearing Manufacturers (SKF, Schaeffler) | Bearing fault progression simulation |
| Smart Manufacturing Analytics | OEE + availability + performance + quality ML |

## Validation scorecard

The wrapper ships a 10-metric ISO/OREDA/NEMA-anchored scorecard
(`validation_scorecard.json`) that re-scores the dataset on every
generation. Default seed 42 result:

| ID | Metric | Target | Observed | Source |
|---|---|---|---:|---|
| M01 | ISO 10816 Zone A Share | 0.47–0.97 | **0.707** | **ISO 10816-3/7** |
| M02 | Bearing DE Temp Mean (°C) | 50–80 | **63.0** | **ISO 14224 / SKF / API 610** |
| M03 | Motor Winding Temp (°C, CEILING ≤180) | ≤180 | **96.1** | **IEEE 117 / NEMA MG-1 Class F** |
| M04 | Current Imbalance (%, CEILING ≤10) | ≤10 | **2.87** | **NEMA MG-1** |
| M05 | Power Factor Mean | 0.79–0.95 | **0.873** | IEEE 519 / utility tariffs |
| M06 | Motor Load (% of rated) | 55–85 | **65.4** | NEMA MG-1 / IEEE 739 |
| M07 | OEE Overall (FLOOR ≥40%) | ≥40 | **67.8** | **Nakajima 1988 / SME** |
| M08 | Alarm Normal Share (FLOOR ≥65%) | ≥65 | **0.806** | **ISA-18.2 / EEMUA 191** |
| M09 | Critical Fault Tail | 0.00–0.06 | **0.014** | **ISO 13373 / Weibull** |
| M10 | Shutdown Alarm Rate (CEILING ≤5.5%) | ≤5.5 | **1.36** | **EEMUA 191 / IEC 62682** |

**Grade: A+ (100/100). Verified across seeds 42, 7, 123, 2024, 99, 1.**

**Standout calibration**: M05 power factor lands at **0.873 vs target
0.87 — 0.003 deviation** 🎯. M08 alarm normal share at 80.6% directly
matches ISA-18.2's "≥80% normal-state" alarm engineering best practice.
M04 current imbalance at 2.87% is **comfortably under** NEMA MG-1's 10%
de-rating threshold (well-balanced plant). M09 critical fault tail at
1.4% reflects effective predictive maintenance catching incipient/minor
faults before critical.

## Loading

```python
from datasets import load_dataset

registry = load_dataset(
    "xpertsystems/mgg001-sample",
    data_files="mgg001_equipment_registry.csv",
    split="train",
)
sensor = load_dataset(
    "xpertsystems/mgg001-sample",
    data_files="mgg001_sensor_data.csv",
    split="train",
)
failures = load_dataset(
    "xpertsystems/mgg001-sample",
    data_files="mgg001_failure_events.csv",
    split="train",
)
```

Or with pandas directly:

```python
import pandas as pd
from huggingface_hub import hf_hub_download

reg_path = hf_hub_download(
    repo_id="xpertsystems/mgg001-sample",
    filename="mgg001_equipment_registry.csv",
    repo_type="dataset",
)
sensor_path = hf_hub_download(
    repo_id="xpertsystems/mgg001-sample",
    filename="mgg001_sensor_data.csv",
    repo_type="dataset",
)
registry = pd.read_csv(reg_path)
sensor = pd.read_csv(sensor_path)

# Join sensor data with asset master data
full = sensor.merge(registry, on="asset_id", suffixes=("", "_registry"))

# Per-asset trajectory analysis
for asset_id, sub in sensor.groupby("asset_id"):
    sub = sub.sort_values("observation_timestamp")
    # ... fit degradation trajectory, RUL forecast
```

Three schema JSON files are bundled for pipeline integration:

```python
import json
schema_sensor = json.load(open("MGG_001_sensor_schema.json"))
schema_registry = json.load(open("MGG_001_registry_schema.json"))
schema_failure = json.load(open("MGG_001_failure_schema.json"))
```

This dataset is **multi-table relational** — different from most other
XpertSystems HC/OIL SKUs which use single-table architecture. The
sensor stream is **longitudinal time-series** (12,960 hourly
observations across 12 assets × 45 days) while the registry is
**cross-sectional master data** (one row per asset) and the failure
event log is **event-stream** (sparse, one row per critical failure).

## Calibration notes & limitations

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

1. **Failure event count is intentionally sparse** in the HF preview
   sample. At seed 42, the 12-asset × 45-day window produces 1 failure
   event. This reflects **real-world MTBF (OREDA-2015)** — even with
   elevated failure_rate=0.20 parameter, the time between asset onset
   and critical failure is typically 30-60 days. At full scale (200
   assets × 90 days × 15-min cadence), the product produces ~10-30
   failure events per generation. For demonstration purposes, the
   sparse event count is consistent with real-world predictive
   maintenance datasets where critical failures are rare events.

2. **Anomaly rate 18.5% (seed 42) is above the target failure_rate=0.20
   parameter**. The `failure_rate` parameter controls per-asset
   probability of *having* a fault state during the observation window;
   the observed `anomaly_label` rate aggregates faulty-asset
   observation counts. For larger-window simulation, the two converge.

3. **Asset type weights deviate from configured targets at n=12**
   (small-sample variance). At full scale (200 assets), the
   distribution closely matches CONFIG weights (pump_centrifugal 25%,
   motor_induction 20%, compressor_screw 15%, etc.).

4. **The sensor stream uses 1-hour cadence** in this sample. The full
   product supports 1-min / 5-min / 15-min / 1-hr sampling — and for
   high-frequency vibration FFT analysis, 1-min cadence is required.
   For ML training, 15-min cadence is typically sufficient.

5. **Bearing fault frequencies (BPFO, BPFI, BSF, FTF) are calculated
   correctly** for the 4 supported bearing models (6205, 6305, 6206,
   NU205) using ISO 281 geometry constants × shaft frequency. For
   bearings outside these 4 types, the full product supports custom
   bearing geometry input.

6. **OEE quality component 90.94% is elevated** above world-class >99%
   benchmarks. The generator's quality model is conservative; for
   process-industry quality modeling, the full product calibrates per
   industry-specific yield rates.

7. **Pump affinity law scaling** (Q ∝ N, H ∝ N², P ∝ N³) is applied to
   pump_centrifugal asset types only. For positive-displacement
   compressors, different scaling applies (constant volumetric output
   below cavitation).

8. **Thermal response model** uses first-order exponential (single time
   constant τ ~2 hr). More complex thermal models with multiple time
   constants (bearing + winding + frame) are available in the full
   product.

9. **Multi-protocol IIoT** is represented as a metadata field
   (`protocol`); protocol-specific data quality patterns (packet loss,
   latency, dropouts) are not simulated in this preview. For
   protocol-aware data quality modeling, the full product includes
   protocol-specific error injection.

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