Multimodal Transportation, Dawei Deep Seaport, Pakbara Deep SeaportAbstract
This paper presents the optimization of a multimodal transportation problem, which focuses on determining the optimal transportation flows in each international trade route involving the optimal transportation mode selection between rail and road as well. The objective of this paper is to minimize the sum of shipping and inland transportation costs both inbound and outbound of Thailand. Linear programming model was applied to solve the optimal cargo flows in each trade route. Dawei and Pakbara deep seaports were considered together with Port Klang and Singapore port in order to be the alternatives sharing with Laem Chabang port rather than using Laem Chabang port only at present for shipping companies. In total, the model consists of 24,330 decision variables and 24,506 constraints. It found that the sum of shipping and transportation costs was slightly reduced only 0.09% and Pakbara port was technically situated in the better geographic location than Dawei port.
