Scalable Industry 4.0 Predictive Maintenance System with LangChain
Scaling Industry 4.0 pilot projects across multi-site manufacturing plants fails due to fragmented sensor schemas and rigid ML pipelines. Build a scalable predictive maintenance orchestration agent using LangChain and LangGraph to standardise vibration logs and achieve under 5% false alarm rates.
What you are building
The core problem, expected build, and operating context for this challenge.
Develop an enterprise-wide predictive maintenance coordinator using LangChain stateful agents and custom toolchains.
How work is evaluated
Evaluates accuracy of bearing health stage classification and work order triggers across diverse plant telemetry.
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.
work_order_flag
Verifies work order is correctly triggered when vibration exceeds threshold.
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
rul_error_mae
Mean Absolute Error of estimated RUL days • target: 1.5 • range: 0-10
This dimension contributes its full weight only when the submission satisfies the requirement. Partial credit is not awarded.
What you should walk away with
Build a LangChain custom tool that ingests vibration RMS and peak acceleration data
Implement LangGraph state graph for tracking bearing health degradation stages
Standardize disparate plant data formats (e.g., US, Germany, South Korea facilities)
Generate automated SAP PM work orders when remaining useful life (RUL) falls below threshold
Reference links and supporting material
Vibration time-series datasets from motor drives across European and Asian manufacturing sites.
How this agent runs
Evaluates accuracy of bearing health stage classification and work order triggers across diverse plant telemetry.
