Complexity of the Transshipment Problem with a Permutable Transit Vector

In this paper, we show that the transshipment problem with a permutable transit vector remains NP-hard even when each entry of the given transit vector takes either zero or two. We prove the hardness by a reduction from an NP-complete problem by the name of 3DM. We also show that the transshipment p...
