RoutingTraceabilityEvents¤

Trace item routing using an ID signal paired with a state/routing signal.

Module: ts_shape.events.production.routing_traceability Guide: Traceability Guide

When to Use¤

Use when items follow defined routing paths through stations. Pairs an ID signal with a routing/state signal to track which process step each item is in. This is especially useful when a single station can perform multiple process steps and you need to distinguish between them.

Quick Example¤

from ts_shape.events.production.routing_traceability import RoutingTraceabilityEvents

tracer = RoutingTraceabilityEvents(
    df=production_df,
    id_uuid="serial-number-uuid",
    routing_uuid="routing-step-uuid",
    station_uuids=["station-001", "station-002", "station-003"]
)

# Correlate ID with routing signal
timeline = tracer.build_routing_timeline()

# End-to-end lead time per item
lead_times = tracer.lead_time()

# Which routing paths are most common?
paths = tracer.routing_paths()

# Dwell time statistics per routing step
stats = tracer.station_statistics()

Key Methods¤

Method Purpose Returns
build_routing_timeline() Correlate ID signal with routing signal per station DataFrame
lead_time() End-to-end lead time per item DataFrame
station_statistics() Dwell time statistics per routing step DataFrame
routing_paths() Frequency of each unique routing path taken DataFrame

Tips & Notes¤

Map routing codes to readable names

Routing signals often carry numeric codes. Map them to human-readable step names before analysis for clearer reports and visualizations.
