Predictive Maintenance & Work Order State Graph with LangGraph and LangChain
Unscheduled machine down-times disrupt production schedules when sensor alarm triggers are not seamlessly translated into maintenance work orders. Construct a stateful workflow graph using LangGraph and LangChain to process vibration sensor alerts, evaluate asset health, and generate ERP work orders. Achieve 100% correct state transitions across complex asset repair workflows.
What you are building
The core problem, expected build, and operating context for this challenge.
Design a stateful LangGraph workflow that orchestrates predictive maintenance alerts through health evaluation, asset lookup, and automated work order dispatch.
How work is evaluated
Evaluates state transition accuracy and work order generation correctness in the LangGraph workflow.
Shared data for this challenge
Review public datasets and any private uploads tied to your build.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
state_transition_validity
Ensures graph executed through all mandatory evaluation nodes without dangling states.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
transition_accuracy
Accuracy rate of conditional edge branching based on severity thresholds. • target: 1 • range: 0-1
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Define state schema graph nodes for telemetry ingestion, asset health evaluation, and work order creation
Implement conditional routing edges based on vibration threshold severity levels
Integrate LangChain tool nodes for external ERP (e.g., SAP / Maximo) work order API dispatch
Reference links and supporting material
Asset telemetry records including motor bearing vibration and temperature metrics associated with historical failure records.
How this agent runs
Evaluates state transition accuracy and work order generation correctness in the LangGraph workflow.
