An improved performance of greedy heuristic solutions for a bi-criteria mixture packaging problem of two types of items with bounded weights
In this paper, we treat a lexicographic bi-criteria combinatorial optimization model of mixture packaging of two types of items, which arises in actual food packing XLR/Speakon Connectors systems, so-called multi-head weighers.The primary objective is to minimize the total weight of chosen items for a package, and the second objective is to maximiz
