TI
Cases or boxes placed on one pallet layer. In TI-HI notation, TI describes the number of cases per layer.
Packing & cutting definitions
PackMize glossary
Concise definitions used across pallet loading, container planning and cutting optimization. Each definition is written to match the assumptions used by the PackMize tools.

HI
Number of loaded layers on a pallet. In TI-HI notation, HI describes how many layers are stacked vertically.
CBM
Cubic metres. CBM is a volume measure: length × width × height in metres. It is useful for reporting but does not prove geometric fit.
Payload
Maximum cargo mass allowed by the relevant pallet, container or transport specification. It excludes or includes tare depending on the specification, so the source definition must be checked.
Tare weight
Weight of the empty pallet, container or equipment before cargo is added.
Pallet utilization
A ratio describing how much of a pallet footprint, loading envelope or payload is used. Area, volume and weight utilization are different measures.
Pallet pattern
The two-dimensional arrangement of cartons on one pallet layer, including orientation and mixed rectangular placements.
Kerf
Material removed by a saw blade or cutting process. A feasible cut plan must reserve this width between relevant cuts.
Cut list
A list of required finished piece dimensions and quantities. An optimizer assigns those pieces to available sheets or stock lengths.
Cutting stock problem
An optimization problem that assigns required lengths or pieces to standard stock while minimizing stock count or waste.
Rectangular nesting
Placement of rectangular parts within rectangular sheets or bins. PackMize currently handles rectangular parts, not irregular-shape nesting.
High Cube container
A shipping container variant with greater internal height than a standard container of similar length. Exact dimensions vary by equipment series.
Proven optimal
A PackMize status used only when the returned solution reaches a valid mathematical bound or a completed exact search proves no better solution exists within the model.
Best solution found
A PackMize status indicating a strong solution was found but global optimality has not been proven.
