What you are building
The core problem, expected build, and operating context for this challenge.
Correlate simulated open62541 station cycle times to identify starvation risks in multi-stage production lines. Propose prioritized buffer dispatch schedules to balance hourly takt time.
Manufacturing Operations Supervisor
Extract station cycle times and buffer levels from simulated open62541 server records.
Compute actual takt time vs target takt time across sequential manufacturing stages.
Detect workstations experiencing starvation or impending buffer overflow.
Construct a revised WIP lot dispatch manifest to re-align line flow with target takt.
Interactive takt-time balancing chart showing buffer deltas, stage starvation alerts, and lot routing dispatch options.
Synthetic station telemetry feeds containing cycle time history, buffer count changes, and parts rejected counts. Starter examples below are synthetic. They are not downloaded records.
open62541 OPC UA Extracts station runtime telemetry and discrete production counters mapped to open62541 OPC UA information nodes.
crewai, pandas, fastapi. CrewAI facilitates multi-agent role division between line bottleneck analysis and dispatch schedule creation. Local or hosted LLM with multi-step reasoning capabilities for dispatch logic.
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.
Detects stations whose actual cycle time deviates more than 15% from line takt time.
Prioritizes starved stations in dispatch schedule output.
Ensures proposed lot moves do not breach downstream buffer limits.

How work is evaluated
Detects stations whose actual cycle time deviates more than 15% from line takt time. Prioritizes starved stations in dispatch schedule output. Ensures proposed lot moves do not breach downstream buffer limits.
Runnable source, pinned dependencies, setup commands, working interface, example outputs, recorded demo, tests, and action logs.
Challenge datasets
Public datasets, plus the private datasets you have access to.
How submissions are scored
These dimensions define what the evaluator checks and which criteria separate a passable run from a strong one.
