Container Loading Planner
Pack mixed pallets into containers with first-fit-decreasing bin packing, stacking, and weight checks.
Container Loading Planner
Upload a pallet list with dimensions, weight, and stackability flags, then plan container loading using first-fit-decreasing bin packing. The planner places larger pallets first, stacks compatible pallets when height permits, and opens a new container when the current one is full. Top-down SVG floor plans show per-container layout. Utilization metrics for weight, floor area, and cube. Supports 6 container presets (20'/40'/40HC/45HC ISO, 53'/48' trailers). 200-pallet limit. CSV export.

Container Loading as Bin Packing
Loading mixed pallets into containers is a classic bin-packing problem. In theory, finding the optimal load is NP-hard. In practice, simple greedy heuristics like first-fit-decreasing (FFD) get within a few percent of optimal for typical warehouse loads. FFD sorts pallets largest-first and places each in the first container where it fits, opening a new container only when necessary.
Stacking and Weight Constraints
Beyond floor area and cube, real container loading must respect weight distribution (to avoid axle overload on trucks) and stacking compatibility (fragile pallets can't have heavy ones on top). The planner accepts a stackable flag per pallet and respects the container's maximum payload. Total weight is checked against the container's payload cap — the most common blocker before cube fills up.
