Logistics skill

The Logistics skill turns Nexma into a supply-chain and routing platform. It models warehouses, fleets, orders, and routes, and optimizes against time windows, capacity, and service level.

What it covers

• Entities. Warehouse, DistributionCenter, Vehicle, Shipment, Order,

Inventory, Route. Each carries typed properties (capacity, time window, cost per mile, dwell time).

• Relationships. DeliveryRoute, InventoryTransfer, OrderFulfillment. Routes

carry sequence, cumulative load, and arrival-time estimates.

• Constraints. Vehicle capacity, delivery-time windows, driver hours-of-service,

cost minimization, service-level agreement targets.

• Constants. Standard vehicle classes (van, box truck, semi), default loading and

unloading times, regional driver-hour rules (DOT in the US, EC 561/2006 in Europe).

• Layer config. Warehouses as 3D sites scaled by capacity, vehicles as moving

markers along route polylines, demand as graduated points.

• Toolbar tools. Generate routes, balance loads across a fleet, simulate one

day's deliveries, export to TMS.

Typical workflow

1. Scope. Draw a service polygon and bring a depot location plus a customer

layer with order weights.

1. Fleet. Define vehicle classes, counts, and shift times.
2. Generate. Ask Jax: "Plan tomorrow's routes for 12 vehicles out of this depot.

Hold under 10-hour shifts. Honor every customer's window."

1. Inspect. Click routes for sequence and timing; hover stops for service time

and cumulative load.

1. Refine. Move stops between routes, lock specific sequences, change vehicle

class — Jax re-runs the VRP solver.

1. Validate. Capacity check, time-window check, hours-of-service check.
2. Export. Route sheets, TMS import files, or GeoJSON from Project → Export.

What Jax is good at, in Logistics specifically

• Vehicle-routing with time windows, capacity, and driver-hour constraints

(VRPTW solver).

• Fleet sizing trade-offs (more vehicles vs longer days) under SLA targets.
• Pick-up and delivery routing with paired-stop constraints.
• Day-of-operations replanning when stops are added, cancelled, or delayed.

Standards

DOT hours-of-service rules (US), EC Regulation 561/2006 (EU drivers), GS1 SSCC shipment identification.

What it does not do (yet)

• Long-haul freight network design (separate skill, planned).
• Cold-chain compliance simulation (temperature-class aware routing only).
• Customs and cross-border documentation.
