Under leveling refers to a specific process in the packaging and assembly of goods. When creating a container or outer packaging from several individual packages, an attempt is made to achieve a specified target weight with the help of equalizing. It is important to achieve this target weight as efficiently as possible (business administration: optimization in operations research ).

Leveling is used in particular in the packaging of "naturally grown" products such as cheese, meat, poultry, fish, and fruit. These products generally have variable weights and should be sorted as efficiently and precisely as possible into a batch with a given fixed weight.

In sales markets where discount chains are very important , such as B. Germany, the equalization is used more and more. Suppliers to these discounters have to deliver fixed-weight cartons when prices are under great pressure. In order to produce packs of variable weight units that are as precise as possible and conform to the weight, sorting systems are used to calculate the contents of the packaging. The contents are determined with mathematical sorting algorithms, mostly from combinatorics ( combinatorial optimization ).

These systems use leveling to determine which individual products have been sorted.
