What you are building

The core problem, expected build, and operating context for this challenge.

Plan maintenance isolations of central chillers and primary feeder lines while utilizing customer thermal energy storage. Minimize contract chilled-water deficit penalties during peak cooling hours.

District cooling operational dispatch engineer

Parse scheduled chiller maintenance work orders, customer peak cooling nominations, and network pipe connectivity.

Simulate hydraulic pressure drop and delivered water temperatures across customer branches using WNTR hydraulic principles.

Synthesize customer chilled-water storage discharge schedules to cover supply shortfalls during maintenance windows.

Generate a bilingual customer notification brief with expected temperature deltas and contingency cooling commitments.

A timeline view showing maintenance windows, hydraulic zone pressure contours, thermal storage levels, and notification draft panes.

Create normalized JSON network graphs containing 12 district cooling customer branches, pipe diameters, chiller nominal capacities, and thermal tanks. Starter examples below are synthetic. They are not downloaded records.

Water Network Tool for Resilience Uses pipe isolation and pressure-dependent delivery algorithms derived from the Water Network Tool for Resilience (WNTR) architecture.

langgraph, pydantic, fastapi. Manages complex state transitions across maintenance scheduling, hydraulic simulation passes, and notification dispatch nodes. Fast hosted model capable of multi-step workflow coordination and bilingual customer communication drafting.

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.

Identifies hydraulic branch pressure deficits below 2.0 bar gauge during single-line chiller isolation scenarios.

Allocates customer thermal energy storage discharging to maintain building delta-T above 8.5 degrees Celsius.

Generates bilateral Arabic and English outage notification packets with precise start, duration, and customer capacity quotas.
