• Bagian dari model transportasi di mana terdapat titik (node) yang berfungsi sebagai demand sekaligus supply:– Transhipment nodes– Pada kasus di mana transhipment lebih menguntungkan
daripada direct supply to demand nodes
• Supply untuk setiap transhipment node adalah total supply
• Demand untuk setiap transhipment node adalah total demand
