Abstract

This paper extends the previous work [9] regarding the two dimensional covering problem to a rectangular three dimensional bin packing problem, where a bin is packed with a set of rectangular boxes, without gaps or overlapping. Our objective is to determine an order of the loading the boxes in the bin so that a box is packed in the bin only if there are no empty spaces down to this box and the origin of the box is in a fixed position. We define a graph representation, similarly with [10, 11], of the packing model so that to obtain an acyclic graph. Starting from this graph it is possible to obtain a topological order of the boxes. At the end we present a kind of topological sorting algorithm for this problem, of linear complexity.
