Production Planning Solver

Turn live ops data into an executable 8-week plan.

The planner reads products, materials, bills of materials, inventory, sales velocity, scheduled work, and open supplier orders; then a constraint optimizer chooses what to make, ship, and buy.

What goes in

The planner uses operational tables, not a spreadsheet approximation.

Input domains

Finished products Material inventory Bills of materials Sales velocity Marketplace channels Open supplier orders Scheduled production Scheduled shipments Supplier lead times Minimum buys and costs Safety-stock rules Capacity bands

Planning phases

1
LoadClean product, material, inventory, order, shipment, and schedule records.
2
ForecastProject channel stock against velocity, safety days, and lead time.
3
BatchGroup products into manufacturing families and production cycles.
4
SolveSelect feasible production, shipment, and supplier-order recommendations.
5
PublishPush plans and health checks to operating tables.

Solving mechanism

Production path is a Google OR-Tools CP-SAT constraint solver; heuristic mode is fallback/debug only.

Published planning outputs

The run publishes validated planning records and audit views to the operating database with clear failure reporting.
Shipment planCreates, updates, cancels, and links fulfillment recommendations.
Production scheduleCreates planned production and preserves locked scheduled work.
Supplier-order forecastCreates planned buys and cancels stale planner-owned recommendations.
Material flow ledgerWrites the full material-week snapshot for operators.
Material readinessShows component readiness for each production order.
Product inventory projectionShows channel inventory, days-on-hand status, and below-safety flags.
Cash scheduleTurns supplier-order timing into cash-plan visibility.
Alerts + plan healthStockout alerts, weekly quality checks, and exception reports.
