+ # Supply Chain Integrity & Track-and-Trace Dataset
33
+
34
+ ## Abstract
35
+
36
+ **30,000 simulated medicine shipment observations** (10,000 per scenario) across three supply chain visibility levels. Variables include serialization, authentication, temperature monitoring, GPS tracking, intermediary count, diversion, tampering, SF product entry, and recall. Three scenarios: serialized (90% serialized, 3% SF), partial visibility (16% serialized, 23% SF), opaque (1% serialized, 69% SF).
37
+
38
+ **This dataset is entirely simulated. It must not be used for supply chain or regulatory decisions.**
39
+

+ ## Usage
47
+
48
+ ```python
49
+ from datasets import load_dataset
50
+ dataset = load_dataset("electricsheepafrica/supply-chain-track-trace", "partial_visibility")
51
+ df = dataset["train"].to_pandas()
52
+ print(df.groupby('serialized')['sf_product_detected'].mean())
