In recent years, the rising competitive environment with shorter product life cycles and high customization forces
industries to increase their flexibility, speed up their response, and enhance concurrent engineering designs. To integrate
these prospects, supply chain collaboration becomes a pertinent strategy for industries to strengthen their
competitiveness. The network design problem is used to implement supply chain collaboration. In the buying and
selling process, sharing information between buyer and supplier are important to obtain a transaction decision. The
optimimum supply chain profit can be identified by mathematical model of network design problem. The Mathematical
Model takes into consideration the uncertainity in negotiation of supply chain, transportation problems, and locationallocation
of products from supplier to buyer in the planning based on the time value of money. The results show that
the model can be used to optimize the supply chain profit. The supplier gets a profit because income were received in
the initial contract, while the buyer profit comes from lower pay.
