Design a phased opening and ramp-up sequence for new DCs/cross-docks across [Regions] over [PlanningHorizon] to hit a [TargetServiceLevel] while minimizing total landed cost under [CapexPerSite] limits. Sequence sites to reduce drayage and middle-mile linehaul, balance inbound/outbound flows, and protect peak capacity. Incorporate lane-level demand curves (seasonality, growth), labor availability, and real estate readiness. Define dependency logic (IT cutover, carrier onboarding, customs/bonded status) and interim backhaul and pooling arrangements. Output format: (1) Location Prioritization table [Site, Go-Live, Rationale, Service Area, Cost Δ/Order, OTIF Δ, Payback]; (2) Ramp Curve table [Week, Throughput, Staffing FTE, Shift Pattern]; (3) Constraint Map (bullet list of critical path items); (4) 3-scenario sensitivity on demand ±[DemandVariancePct] and labor rate ±[LaborVariancePct]; (5) Go/No-Go checklist with decision gates and exit criteria.
