Root-Cause Isolation via Bidirectional Traceability in Industrial Automation

A manufacturer of industrial Variable Frequency Drives (VFDs) and power control modules produces high-voltage power conversion units for water treatment facilities and automated factory floors. Each drive undergoes rigorous end-of-line electrical testing before field installation.

How the work runs

The pressure that made this worth automating, the steps the system runs, and what came out the other side.

Pressure & Trigger Points

A field failure is reported for an installed VFD (Serial # VFD-9021-X) that suffered a thermal power stage breakdown after 100 hours of operation.
Quality engineers must quickly determine whether the failure was caused by shop-floor assembly error, incorrect test parameters, or a defective vendor component lot.
Legacy traceability is strictly unidirectional; finding whether other active WIP jobs contain components from the same suspect batch requires opening hundreds of physical job jackets.

Backward Serial Traceability

Quality engineers input Serial # VFD-9021-X into Anvaya Bidirectional Traceability. The system instantly traces backward from the failed unit to identify the exact power MOSFET lot (Lot # MOSFET-441-A) used during assembly.

Input Signal:

Real-time operational telemetry & queue

Reasoning Pattern:

MCP grounded vector inference

Governance Gate:

Policy constrained with audit write-back

Verified Business Outcomes

Investigation time from field failure report to root-cause isolation drops from 5 days to 20 minutes.
48 defective VFD units currently in production are intercepted and reworked before shipping to customer sites.
The manufacturer submits an indisputable, data-backed warranty claim to the semiconductor vendor, recovering 100% of material rework costs.
