| Summary: | 碩士 === 國立交通大學 === 交通運輸研究所 === 93 === Under the pressure of international competition and the prosperity of information technology, many logistical companies have produced. They offer quick and convenient service of International Logistics directly among countries. During the process of transportation among countries, the vehicle transition and the vehicle choice is a very important problem, so intermodal appears. However, the factor of dynamic is usually ignored while choosing transportation vehicles. Actually, time does have effects on the adequacy of resources, since resources change with time and are limited. How to integrate land, sea, and air transportation vehicles to attain the utmost of resource allocation is what we care about.
This research is to analyze what happens during the process of among supply chain and also applying related mathematic programming to construct a generalized model, such as 0-1 integrate programming, which takes transportation vehicles, routes, and transfer posts three decision variable into consideration, and multi-objective programming, which contains two objective. Then, use Lingo8.0 software to find out the answer.
The following are the two consequences: If we take Tianjin as the start of transportation, to combine sea and highway two transportation would be the best resolution. If we take Shanghai and Guangzhou as two starts, the best transportation combination is sea and railway. While adjustments ratio of cost objective and time objective, the best transportation combination would change with it. Thus, the intermodal model of this research has generality, which means it can apply to most of situations and hope to utilize this model to supply as a resource of operation and management strategies and to promote the ability of competition internationally.
