본 연구는 지속가능한 물류활동에서 관심을 받고 있는 내항해운(연안해운)의 물류네트워크를 파악하기위한 기초분석으로서 연안여객항로에 관하여 네트워크를 파악하였다. 최근에 기존의 계량적 통계분석방법을 뛰어넘어 존재하고 있는 구조와 실체를 파악하기위해 사회연결망분석이 도입되고 있는 상황에서, 우리나라 연안해운항로의 네트워크를 파악하고자 하였다. 내항해운은 화물운송과 여객운송으로 구별되나 본 연구에서는 화물선만 고려하였다. 국가물류통합정보센터와 해운항만물류정보시스템을 활용하여 한국의 내항해운의 중심성을 분석하였다. 중심성 분석을 위해서 화물선 출입항 척수와 화물처리량을 변수로 사용하여 Pajek과 UCINET 등의 SNA 프로그램을 이용한 결과 내항해운 네트워크를 도식화하고 파악하였다. 결과적으로 네트워크의 node에 해당하는 항만 중에서 어떤 항만이 가장 중요한 노드인지를 찾고, 네트워크 구조가 얼마나 소수의 중요한 항만에게 집중되는 것인지를 확인하기 위하여 중심성 분석을 통해 파악하였다.

The automotive supply chain is increasingly complex as automakers seek more profitable solutions with global out-sourcing and manufacturing strategies. In the automotive industry, using returnable plastic containers (RPCs) is very common for domestic operations, but for internationally, it has not been considered by many companies because of issues such as overall distance and difficulty of control. The results of this simulation can help to analyze the interactive and coherent behavior of packaging and supply chain systems. The data obtained from the model can be applied to make substantial decisions for choosing the most profitable packaging types, at the same time as it can lead to designing an optimum supply chain for RPCs used in international supply chains.

최근에 남북철도를 통한 대륙철도의 움직임이 우리들에게 비상한 관심과 함께 실질적인 동북아의 물류거점으로서의 우리의 역할이 급부상하고 있다. 그간 제4차국토종합개발계획과 국가기간교통망계획등에서 한반도의 물류중 심지구상이나 X축의 고속철도망등이 현실적인 과제로 다가온 것이다.(중략)

This research is to focus on the method of moving line optimization in Agricultural Industry, especially Garak Wholesale Market Modernization Project, by using simulation tool. As everybody knew, it's very difficult to apply the SCM operation rules in Agricultural Industry, because the standardization system in Agricultural Industry was not completed. The five flow management factors, vehicle moving line management, customer moving line Management, Logistics Device Moving Line Management, Working Person Moving Line Management, Product display moving line management, are needed to be optimized on the basis of standardization rules, and to achieve this will be the good infrastructure to make the Agricultural SCM system. It's very different between the SCM structure of manufacturing industry and logistics industry and the SCM structure of Agricultural Industry, because the SCM in manufacturing is occur in the basis of flow management, on the contrary, the SCM of Agricultural Industry is on the basis of activity management. For these reason, this study is the first approach to apply the simulation method in the part of moving line optimization in Agricultural SCM, and in near future, This study will help all designers and operators to apply the simulation work in the part of agricultural SCM, and we hope that next advanced study will continue by using this study.

국제기구와 우리 정부는 그 동안 아시아 지역과 유럽지역의 경제협력과 발전을 도모하기 위한 철도망 구축 연구와 검토를 지속해 왔다. 극동지역의 철도교통망 구성에 있어서는 한반도와 시베리아 횡단철도(TSR)와의 연결이 중요한 교통 축으로 대두되고 있다. 동북 아시아 지역에서 유럽지역으로의 철도교통루트는 중국횡단철도(TCR), 만주횡단철도(TMR), 몽골횡단철도(TMGR)를 통하여 연결이 가능하며, 이중 한반도와 직접 연결되는 철도는 TCR과 TSR이다. 수송거리와 시간의 단축, 비용의 절감이라는 경제적 이유와 유라시아 물류망 확보라는 측면에서 이들 지역 관계국가들은 깊은 관심을 가지고 있다.

It is general that mostly congested sections of national backbone networks have been improved based on the national network expansion plan. However, in case of intermodal terminals which are origins of logistics, it is still so congested that travel time between origin and destination is long. Therefore, intermodal transportation systems plan of major intermodal terminals for the intermodal connector networks between intermodal terminal and national backbone network or intermodal terminal was established. With the limitation of priority methodology applying to intermodal connector facility under existing methodology, this study suggests an improved priority methodology. This study includes characteristics of terminal on the hierarchical structure and assessment list, but it does not concentrate on the specific terminal type through survey. To avoid a certain concentration, budget constraint for each terminal type was considered ahead of priority. Finally priority methodology was developed with two-step assessment under consideration that specific terminal is not involved in intermodal connector facility project. As a result of calculating weights by survey, effects such as d/c and accessibility fluctuations index through project implementation gain high weight, and degree of region underdevelopment gets next. Although the methodology in this study could not yields the priority by assessment list, it will be useful for setting the direction on policy related to intermodal connector facility projects.

This paper is to evaluate the performance of a proposed hybrid genetic algorithm (pro-HGA) approach using closed-loop supply chain (CLSC) model. The proposed CLSC model is a integrated supply chain network model both with forward logistics and reverse logistics. In the proposed CLSC model, the reuse, resale and waste disposal using the returned products are taken into consideration. For implementing the proposed CLSC model, two conventional approaches and the pro-HGA are used in numerical experiment and their performances are compared with each other using various measures of performance. The experimental results show that the pro-HGA approach is more efficient in locating optimal solution than the other competing approaches.
