In this paper, a variable sized bin
packing problem with conflicts is addressed. The problem includes assignment of
items to the variable sized bin categories considering weight and volume
capacity of bins while avoiding joint assignments of items that are in
conflict. The objective is to minimize the total cost of bins used to assign
all items. Bin packing problem, one of the classical combinatorial optimization
problems, is known to be NP-hard and thus, the variable sized bin packing
problem is NP hard as well. In the literature exact and approximation
algorithms are used to solve this problem. In this paper a model based on
Genetic Algorithm is proposed to provide decision support for variable sized
bin packing and related problems. The performance of the model is tested on the
derived problems and results are presented.

Bin
packing problem (BPP) is a combinatorial NP-hard problem that has variations
including one, two and three dimensional packing, variable sized packing and
packing with constraints. In the literature, exact and approximation algorithms
have been mostly used to solve bin packing problems. Genetic Algorithms are meta-heuristic methods that
have been applied to a vast majority of well-known optimization problems
including the bin packing problems. In this paper, a variant of bin-packing
problem for variable bins is addressed. The capacity constraints including
volume and weight are given; moreover, to avoid item conflicts is defined as an
additional constraint. A decision support model utilizing the genetic algorithm
is introduced for this variant of the BPP. The performance of the model is tested with
sample input, the results obtained are presented and discussed in the results
section.
