Challenge brief

What you are building

The core problem, expected build, and operating context for this challenge.

Parse open62541 OPC UA lot tracking records to verify material substitutions in multi-level assemblies. Flag products using unauthorized alternative components against master bill-of-materials rules to maintain quality compliance.

Plant Quality Compliance Engineer

Extract serialized component binding logs and material identifiers from open62541 OPC UA structures.

Retrieve authorized substitution lists and primary component requirements from the master bill-of-materials.

Compare actual consumed component lots against authorized substitution lists for each assembly level.

Generate substitution compliance exception reports detailing unauthorized lot usages and affected product serial numbers.

Audit dashboard web UI displaying compliance statuses and flagged unauthorized material substitutions.

Create simplified synthetic app records representing normalized open62541 hierarchical assembly data and master BOM substitution rules in JSON fixtures. Starter examples below are synthetic. They are not downloaded records.

open62541 OPC UA Uses the open62541 OPC UA information modeling guidelines for hierarchical variable nodes to map component usage.

qdrant, pydantic, fastapi. Qdrant enables rapid vector and metadata filtering to cross-reference consumed materials against allowed substitution sets across deep assembly hierarchies. Requires a local or remote reasoning model to process multi-level BOM structures and apply substitution rules.

Submit runnable source, pinned dependencies, setup commands, a working interface, example outputs, and a recorded end-to-end demo. Include tests and an action log.

Traces components in the open62541 hierarchy to verify their presence in BOM substitution lists.

Generates exception reports for sub-assemblies containing unapproved materials.

Handles multi-level assemblies safely without recursive deadlocks.

Flags empty or malformed material records where required components are missing.

Outputs compliance audit suggestions for warehouse and quality verification; does not issue live ERP commands. Use mock external writes. Require human review before any real deployment.
