HAPE3D—a new constructive algorithm for the 3D irregular packing problem

Xiao LIU,Jia-min LIU,An-xi CAO,Zhuang-le YAO

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 5,   Pages 380-390 doi: 10.1631/FITEE.1400421

Abstract: We propose a new constructive algorithm, called HAPE3D, which is a heuristic algorithm based on the principleHAPE3D can deal with arbitrarily shaped polyhedrons, which can be rotated around each coordinate axisThe most outstanding merit is that HAPE3D does not need to calculate no-fit polyhedron (NFP), which isa huge obstacle for the 3D packing problem.HAPE3D can also be hybridized with a meta-heuristic algorithm such as simulated annealing.
