How CubeMaster calculates space utilization, multi-stop routing sequences, axle load balance, and 3D packing patterns in real time.
How CubeMaster transforms raw order lines into dynamic, crash-free 3D packing manifests in sub-second execution speed.
Processes SKU dimensions, weights, orientation limits ("This Side Up"), tilt angles, stack values (heavy base vs. fragile top), and hazmat class segregation groups.
Decomposes container volume into maximal empty 3D cuboids \((x, y, z)\). Calculates optimal corner points and enforces base contact support ratios (e.g. 80%+ contact area).
Formulates 3D Center of Gravity \((CG_x, CG_y, CG_z)\) relative to kingpins and tandem rear axles, ensuring DOT highway weight compliance and reefer airflow gaps.
Executes Last-In-First-Out (LIFO) drop-off sequencing for multi-stop delivery routes, FEFO expiration date pulling, step-by-step loading maps, and XML/JSON manifests.
CubeMaster's load optimization engine relies on advanced heuristic space-decomposition models to solve the 3D Container Loading Problem (CLP) and 3D Bin Packing Problem (3D-BPP). Rather than relying on simple trial-and-error, the algorithm executes structured geometric calculations:
The 3D space inside a container or truck is modeled as dynamic spatial coordinates \((x, y, z)\). Whenever a cargo box is placed, the remaining space is instantly decomposed into maximal empty rectangular cuboids, generating new candidate corner points for subsequent items.
Each rectangular item can rotate across up to 6 spatial orientations (Length, Width, Height axes). The algorithm filters out invalid rotations based on tilt rules, top-load fragility limits, and custom orientation restrictions.
To prevent boxes from tipping or crushing during transport, the engine enforces a strict base surface support ratio (e.g. minimum 80% bottom contact with underlying items or floor). Heavy items are strictly prioritized at lower elevation layers.
Calculates the 3D Center of Gravity \((CG_x, CG_y, CG_z)\) relative to the vehicle's kingpin and tandem rear axles. Ensures front and rear axle load limits satisfy DOT highway safety regulations.
When building loads for multi-destination delivery routes, the algorithm arranges cargo so that goods for Stop #1 are accessible at the rear door without moving cargo destined for Stop #2 or Stop #3, avoiding unloading delays and warehouse re-work.
From Fortune 500 retail networks to cold-chain dairy logistics and hazmat chemicals, see how CubeMaster's rules translate into operational cost savings.
Problem: 200+ mixed SKUs shipped to 5 retail stores in 53 FT trailers caused dock unloading delays and damaged apparel.
Algorithm Solution: Enforces Sequence Grouping & LIFO rules (Store-5 loaded at nose, Store-1 at door) and Stack Values (heavy household items below, light apparel on top).
Problem: Milk and cheese crates expiring at different dates risked food spoilage if loaded out of chronological order.
Algorithm Solution: Leverages the Pulling Rule (FEFO) using Storage Dates to ensure nearest-expiration items fill the refrigerated truck first before backfilling remaining space.
Problem: Irregular frozen meal crates caused collapsed pallets during ocean shipping in 40 FT reefer containers.
Algorithm Solution: Applies Make Top Flat = ON with an 85%+ base contact support threshold, ensuring stable multi-layer pallet loads with cold-air circulation gaps.
Problem: 280kg engine block crates mixed with light wiring harnesses caused ocean vessel container tilt and port rejections.
Algorithm Solution: Sets strict Max Layer = 1 limits on heavy engine blocks and executes 3D weight balancing to keep the center of gravity centered.
Problem: Temperature-sensitive vaccine coolers required strict "This Side Up" orientation inside contoured LD3 and LD7 ULD containers.
Algorithm Solution: Locks Upright-Only orientation matrix and segregates lab equipment from vaccine kits to streamline customs clearance.
Problem: 55-gallon solvent drums (Class 3) and dry chemical boxes (Class 8) required strict regulatory separation.
Algorithm Solution: Uses Group Segregation (Do Not Mix) with floor placement for 450lb drums and automatic generation of warehouse Loading Maps.
