다수의 원유 선적항으로부터 여러 정유공장으로 수송된 원유를 정제하여 생산한 제품유를 글로벌 수요시장으로 배분하는 2단계 석유물류네트워크의 최적화는 글로벌 석유 메이저의 중요한 의사결정문제이다. 본 연구는 제품유 시장의 가격 및 수요 변동의 영향을 반영하여 원유 수송, 정제 및 제품유 배분을 최적화하기 위한 석유물류네트워크의 로버스트 추계적 모형을 제시하고 있다. 계산실험은 제품유 시장의 가격 및 수요 변동에 관한 시나리오 기반의 데이터를 사용하여 최적화 모형에 적용하였으며, 그 결과를 바탕으로 제시한 최적화모형의 유용성과 타당성을 검증하여 보고하고 있다.

The objective of this study is to develop a supply chain-based freight distribution channel choice model considering shippers' logistics behaviors which will be used for freight demand estimation. For this purpose, this study utilized the distribution channel data of the petrochemical and automobile industries collected by KTDB center. The distribution channel choice models for these industries were developed by including transport mode, time, cost, and shipment size. It was found that the multinomial logit model with transport cost, time and shipment size is the best, and as shipment increases, bigger transport mode is preferred. Generally direct distribution channel with small truck was preferred over the one using distribution center and/or big truck.

The Seosan-Daesan Port is a representative trade port in Chungnam, and has the sixth largest total cargo throughput and the third largest oil cargo throughput in Korea. However, research on this port's development is lacking relative to that for Busan Port, Incheon Port, and Gwangyang Port, and no study exists that suggests the direction of the development strategy for Seosan-Daesan Port. This study discusses the future role of Seosan-Daesan Port in preparation for a rapidly changing future and the development strategy that should be established. Using the AHP, a development strategy is provided for Seosan-Daesan Port from short/mid-term and long-term viewpoints for three aspects: operation activation, infrastructure construction, and policy support. Operation activation is chosen as the most significant factor from a short/mid-term viewpoint, whereas infrastructure construction is recognized as important from a long-term viewpoint. Specifically, from a short/mid-term viewpoint, sustainable container cargo attraction, multipurpose dock construction, management pier construction, and opening of international passenger ferry lines are important factors while from the long-term viewpoint, hinterland construction, petrochemical industry cluster construction, automobile industry cluster construction, and management improvement system are important. Establishing action plans for each strategy and a cooperative network for sharing goals and strengthening cooperation is necessary.
