Bin packing with lexicographic objectives for loading weight- and volume-constrained trucks in a direct-shipping system

Heßler, Katrin; Irnich, Stefan; Kreiter, Tobias; … - In: OR Spectrum 44 (2021) 2, pp. 1-43

We consider a packing problem that arises in a direct-shipping system in the food and beverage industry: Trucks are the containers, and products to be distributed are the items. The packing is constrained by two independent quantities, weight (e.g., measured in kg) and volume (number of...
