2. Contents Introduction Literature review Paper problem

3. Introduction Design how to transport in the supply chain Objective reduce costs, reduce transportation time Transportation modes railway(train), highway(truck), waterway(ship)

4. Review Truck transportation Solution techniques Transportation rates (uniform freight classification) Mathematical model (LP, algorithms) Simulation model

5. Problem A B C D E G truck ship train

6. Design Decentralized warehouse 3 ways of transportation railway (maybe just only one choice) waterway (maybe just only once choice) highway (alternative choice)
