Instances for the two-dimensional heterogeneous vector bin packing problem

The dataset consist of 56 instances for the two-dimensional heterogeneous vector bin packing problem.

Six small instances with 10, 11, 12, 13,
15 and 20 items, as well as 50 randomly generated
large instances were considered. Weights and
volumes of items were randomly uniformly chosen
integer values from [1;15] tons and [1;25]m³,
respectively. The set of large instances had 5 instances
with each of the following numbers of
items: 50, 70, 100, 120, 150, 200, 350, 500, 750
and 1000.
