In this paper, the selection of transport route for import-export container cargo based on the sacrifice model and CO₂ emission was investigated. At first, the transportation of import-export container cargo, the transport share of each transport route, the CO₂ gas emission, the sacrifice model and the time value of import-export container cargo were investigated. And next, the selection of transport route based on the sacrifice model was investigated for the transport of import-export container cargo from Seoul to Pusan Port. Finally, the transport route was also selected by using the sacrifice model including the effect of CO₂ emission. The research results show that the transport route selection results of import-export container cargo based on the sacrifice model represents the present status of the transportation of import-export container cargo very well. And also the research results show that the reduction of transport time was very effective to increase the share of coastal transportation.

In this paper, we investigate the selection of transport route for import-export container cargo based on the sacrifice model and environmental cost of transport route. At first, sacrifice model. environmental cost of transport, the transportation and the transport share of import-export container cargo are investigated briefly. And next, the transport time and cost, the environmental cost which is caused by cargo transport are investigated for the transport of import-export container cargo from Pusan Port to Seoul. And also we calculate the sacrifice of each route by using the sacrifice model including the environmental cost. Finally we decide the transport route of import-export container cargo by using the sacrifice of each transport route. From the research results, we confirm that the road transport share decreases and the coastal transport share increases when the environmental coast of transport is considered.

In this paper, we investigate the selection of transport route for import-export container cargo based on the sacrifice model and environmental cost of transport route. At first, the sacrifice model, environmental cost of transport, the volumes and the transport share of import-export container cargo are investigated briefly. And next, the transport time and cost, the environmental cost which is caused by cargo transport are investigated for the transport of import-export container cargo from Busan Port to Seoul. And also we calculate the sacrifice of each route by using the sacrifice model including the environmental cost. Finally we decide the transport route of import-export container cargo by using the sacrifice of each transport route. From the research results, we confirm that the road transport share decreases and the coastal transport share increases when the environmental coast of transport is considered.

This study aims to clarify current situation of transportation flow and determine to demand forecasting in new route between Korea and Mongolia. By follows the mongolia government information, there will be open 5 new routes in nearest 10 years. Thus, this study purpose is determining the efficiency way by consider time and cost factors for new route between Korea and Mongolia.

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.

본 논문은 AGV를 사용하는 물류자동화 공장에서 운송 시간을 단축하기 위해 최단 다 경로 알고리즘을 제안한다. 최단 다 경로 알고리즘은 A* 알고리즘을 보완한 것으로써 경로 분기점에서 최단 거리 선택을 위한 휴리스틱 함수($\hat{h}$(n))보다 작은 모든 간을 선택하여 저장하고 이를 재 탐색함으로써 다수의 경로를 생성한다. 생성된 경로를 본 논문에서 제안하는 소요시간 산출 방법을 이용하여 예상 소요 시간을 산출함으로써 최단시간에 목적지에 도달 가능한 최적 경로를 선택할 수 있음을 증명한다.

Since the signing of the Korea-Europe Free Trade Agreement, the volume of trade transactions between South Korea and Europe has increased. The traditional single-mode transport system has been transformed into an intermodal transport system using two or more modes of transport. In addition, the conventional sea and air transport routes have been restricted, leading to a decline in Korean exports to Europe, and the rail transport mode is becoming mainstream in the market due to the influence of COVID-19. This paper focuses on the China-Railway Express to explore a new intermodal transport route from Korea to Europe. First, the fuzzy analytic hierarchy process (AHP) is used to evaluate the factor weights when selecting intermodal transport routes from Korea to Europe. Then, the TOPSIS (Technique for Order of Preference by Similarity to Ideal Solution) method is used to rank three alternatives. The results show that among the four factors (total cost, total time, transportation capability, and service reliability), the total cost is the most significant factor, followed by the total time, service reliability, and transportation capability. Furthermore, the alternative route 1 (Incheon-Dalian-Manchuria-Hamburg) is preferred.

물류업계는 배차 운송하기 위한 많은 알고리즘, 차량경로문제, 차량일정계획, GIS, GPS 등의 여러 연구를 진행하고 있다. 하지만 물류시장에 배송물량은 늘어나지만 배송을 하기 위한 차량과 기사는 한정되어 있으며 다단계 거래구조로 인해 수수료가 발생하여 최말단에 있는 화물차주만 수익이 감소한다. 이런 문제에 의해 차량주인(차주)는 운송장소와 운송비에 중점을 두고 배송 건을 선택하여 운송을 하고 있다. 본 논문에서는 이러한 물류기업의 배차문제와 차주 운임비 문제 해결을 위하여 운송비 기반배차 시스템의 정보화를 실현하기 위한 기초적인 데이터 구조를 제안하고, 운송비 중심의 배차 알고리즘이 적용된 배차 시스템을 물류업체에 적용한 결과를 제시하였다.

세계 및 한국경제의 성장과 함께 항공운송 시장의 급속한 확대에 따라 대한민국에서의 국제항공 운송 수요는 꾸준히 증가하게 됨에 따라 한국의 관문 역할을 담당하던 김포국제공항의 수용능력은 한계에 이르게 되었다. 따라서 정부는 김포국제공항을 대체할 인천국제공항을 건설하여 운영하는 한편 김포국제공항에는 한국 중국 일본의 수도를 포함한 몇몇 도시를 연결하는 근거리 중심의 국제선이 취항하게 되면서 공항운영에 대한 새로운 패러다임을 형성하게 되었다. 대한민국의 수도 서울의 항공교통을 위한 공항이 제한적이지만 복수공항 체계로 운영되면서 인천공항과 김포공항을 이용하는 항공여객은 공항 이용 시 선택의 기회가 주어지면서 공항운영자는 여객의 공항선택에 영향을 주는 요소에 관심이 점차 증대되고 있는 현실이다. 그러나 현재 국내에서는 항공여객의 항공사 선택에 관한 연구는 많이 이루지고 있으나 항공여객의 공항선택에 관한 연구는 상대적으로 미흡한 실정임을 부인할 수 없다. 따라서 본 연구는 항공여객의 공항선택에 미치는 속성이 무엇이고 속성에 따른 중요도와 만족도를 측정하여 공항운영자의 공항운영과 활성화 전략수립에 대한 정보를 제공하는데 목적이 있다. 본 연구에서는 김포공항 국제선 이용객을 표본으로 선정하여 설문조사를 실시하여 IPA 분석과 GAP분석 및 경로분석 기법을 사용하여 분석하였다.

In this paper, we propose an algorithm that enables near-field delivery at a faster and lowest cost to meet the growing demand for delivery services. The algorithm proposed in this study involves subway passengers (shipper) in logistics movement as delivery sources. At this time, the passenger may select a delivery logistics matching subway route. And from the perspective of the service user, it is possible to select a delivery man whose route matches. At this time, the delivery source recommendation is carried out in a text similarity measurement method that combines TF-IDF&N-gram and BERT. Therefore, unlike the existing delivery system, two-way selection is supported in a man-to-man method between consumers and delivery man. Both cost minimization and delivery period reduction can be guaranteed in that passengers on board are involved in logistics movement. In addition, since special skills are not required in terms of transportation, it is also meaningful in that it can provide opportunities for economic participation to workers whose job positions have been reduced.
