Build a Port-Adjacent Hauler Appointment Rescheduler and Weather Delay Planner

Monitor Singapore real-time rainfall data to reschedule hauler container collection slots at port terminals. Calculate slipway congestion risks and balance driver shifts across alternative pickup intervals.

Fleet Logistics Dispatcher

Ingest terminal hauler appointment rosters and container pickup deadlines for PSA terminals.

Fetch real-time rainfall and storm warning telemetry from data.gov.sg weather APIs.

Compute rain-induced transit delays and gate buffer windows for heavy transport vehicles.

Propose non-conflicting appointment rescheduling slots and notify carrier drivers via formatted alerts.

A dynamic dispatch timetable showing rain radar overlays, slot utilization gauges, and side-by-side rescheduled appointment proposals.

Query data.gov.sg real-time weather rainfall endpoints combined with synthetic prime mover schedules in CSV format. Starter examples below are synthetic. They are not downloaded records.

Singapore open data API Extract real-time weather APIs from data.gov.sg to calculate heavy transport travel delay allowances.

dspy, fastapi, pandas. DSPy compiles robust prompt programs to negotiate optimal schedule adjustments under hard boundary constraints. Local or hosted LLM with strong constraint satisfaction capabilities.

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.

Polls live Singapore rainfall APIs to flag heavy weather conditions above 15mm/hr.

Reschedules terminal pickup slots without violating driver statutory rest limits.

Produces updated fleet dispatch schedules with verified slot adjustments.

Maintains zero overlapping gate appointments for identical container transport chassis.

Coordinates internal fleet scheduling; does not submit automated binding requests to actual port authority systems. Use mock external writes. Require human review before any real deployment.
