Challenge

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.

Delivery guide

How work is evaluated

Evaluation

Evaluates state transition accuracy and work order generation correctness in the LangGraph workflow.

Datasets

Shared data for this challenge

Review public datasets and any private uploads tied to your build.

Evaluation rubric

How submissions are scored

These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.

Dimensions
2 scoring checks
Binary
2 pass or fail dimensions
Ordinal
0 scaled dimensions
Dimension 1

state_transition_validity

Ensures graph executed through all mandatory evaluation nodes without dangling states.

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Dimension 2

transition_accuracy

Accuracy rate of conditional edge branching based on severity thresholds. • target: 1 • range: 0-1

Binary check

This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.

Learning goals

What you should walk away with
