  • This study aimed to determine relationships among risk factors influencing container port operation using Bayesian network. Risk factors identified from prior studies were classified into five groups: human error, machinery error, environmental risk, security risk, and natural disasters. P anel experts discussed identified risk factors to fulfil conditional probability tables of the interdependence model. The interdependence model was also validated by sensitivity analysis and provided an interrelation of factors influencing the direction of each other. Results of the interdependence model were partially in line with results from prior studies while practices in the global port industry confirmed interrelationships of risk factors. In addition, the relationship between top-ranked risk factors can provide a schematic drawing of the model. Accordingly, results of this study can expand the prior research in the Korean port industry, which may help port authorities improve risk management and reduce losses from the risk.

  • The synchronized operation of a quay crane(QC) and a transfer crane(TC) increases the productivity of a container terminal. In this paper, analytical models are suggested for the optimal number and the optimal operation of the yard trucks (YTs) which travel between a quay crane and a transfer crane in a container terminal. YT may represent yard tractor, AGV and shuttle carrier. The analytical models are so simple and useful that the analysis and the results of this paper can be used not only in container terminal practices but also in many other application fields.

  • Sustainability is a broad concept involving economic, social and environmental issues in operational and managerial processes. To assist ports to implant sustainability practices into their operations, this paper conceptualizes the structure of sustainability practice in port operations, based on interviews undertaken at Busan port in early 2013. Results revealed that, as a strategic practice to improve their internal business processes, sustainability practices necessitate the simultaneous pursuit of container traffic growth, low environmental impacts and corporate responsible image making, operational efficiency, efficiency of the use of the port area and sustainable growth. Through thematic analysis, the relevant practices were clustered into four sub-dimensions incorporating environmental technologies, continual monitoring and upgrading, internal process improvement, and cooperation and communication. Further, reporting the relevant issues such as barriers and challenges in carrying out sustainability practices, the findings provide useful insights for strategic agenda to assist ports to incorporate sustainability practices in their operations.

  • As the world becomes more globalized, business competition becomes fiercer, while consumers' needs for less expensive quality products are on the increase. Business operations make an effort to secure a competitive edge in costs and services, and the logistics industry, that is, the industry operating the storing and transporting of goods, once thought to be an expense, begins to be considered as the third cash cow, a source of new income. Logistics centers are central to storage, loading and unloading of deliveries, packaging operations, and dispensing goods' information. As hubs for various deliveries, they also serve as a core infrastructure to smoothly coordinate manufacturing and selling, using varied information and operation systems. Logistics centers are increasingly on the rise as centers of business supply activities, growing beyond their previous role of primarily storing goods. They are no longer just facilities; they have become logistics strongholds that encompass various features from demand forecast to the regulation of supply, manufacturing, and sales by realizing SCM, taking into account marketability and the operation of service and products. However, despite these changes in logistics operations, some centers have been unable to shed their past roles as warehouses. For the continuous development of logistics centers, various measures would be needed, including a revision of current supporting policies, formulating effective management plans, and establishing systematic standards for founding, managing, and controlling logistics centers. To this end, the research explored previous studies on the use and effectiveness of logistics centers. From a theoretical perspective, an evaluation of the overall introduction, purposes, and transitions in the use of logistics centers found issues to ponder and suggested measures to promote and further advance logistics centers. First, a fact-finding survey to establish demand forecast and standardization is needed. As logistics newspapers predicted that after 2012 supply would exceed demand, causing rents to fall, the business environment for logistics centers has faltered. However, since there is a shortage of fact-finding surveys regarding actual demand for domestic logistic centers, it is hard to predict what the future holds for this industry. Accordingly, the first priority should be to get to the essence of the current market situation by conducting accurate domestic and international fact-finding surveys. Based on those, management and evaluation indicators should be developed to build the foundation for the consistent advancement of logistics centers. Second, many policies for logistics centers should be revised or developed. Above all, a guideline for fair trade between a shipper and a commercial logistics center should be enacted. Since there are no standards for fair trade between them, rampant unfair trades according to market practices have brought chaos to market orders, and now the logistics industry is confronting its own difficulties. Therefore, unfair trade cases that currently plague logistics centers should be gathered by the industry and fair trade guidelines should be established and implemented. In addition, restrictive employment regulations for foreign workers should be eased, and logistics centers should be charged industry rates for the use of electricity. Third, various measures should be taken to improve the management environment. First, we need to find out how to activate value-added logistics. Because the traditional purpose of logistics centers was storage and loading/unloading of goods, their profitability had a limit, and the need arose to find a new angle to create a value added service. Logistic centers have been perceived as support for a company's storage, manufacturing, and sales needs, not as creators of profits. The center's role in the company's economics has been lowering costs. However, as the logistics' management environment spiraled, along with its storage purpose, developing a new feature of profit creation should be a desirable goal, and to achieve that, value added logistics should be promoted. Logistics centers can also be improved through cost estimation. In the meantime, they have achieved some strides in facility development but have still fallen behind in others, particularly in management functioning. Lax management has been rampant because the industry has not developed a concept of cost estimation. The centers have since made an effort toward unification, standardization, and informatization while realizing cost reductions by establishing systems for effective management, but it has been hard to produce profits. Thus, there is an urgent need to estimate costs by determining a basic cost range for each division of work at logistics centers. This undertaking can be the first step to improving the ineffective aspects of how they operate. Ongoing research and constant efforts have been made to improve the level of effectiveness in the manufacturing industry, but studies on resource management in logistics centers are hardly enough. Thus, a plan to calculate the optimal level of resources necessary to operate a logistics center should be developed and implemented in management behavior, for example, by standardizing the hours of operation. If logistics centers, shippers, related trade groups, academic figures, and other experts could launch a committee to work with the government and maintain an ongoing relationship, the constraint and cooperation among members would help lead to coherent development plans for logistics centers. If the government continues its efforts to provide financial support, nurture professional workers, and maintain safety management, we can anticipate the continuous advancement of logistics centers.

  • Globalization and regionalization are major trends in the international economic system. The severe competition among countries has signalled the need for a new international trade system as prescribed by the WTO, which regulates international trade practices. Additionally, expanding the activities and role of the Pan-Yellow Sea area in the world has a very important function in terms of regional cooperation and logistics environment. In this paper, the trading conditions and shipping transport problems of the Pan-Yellow Sea area (North-East Asia) were investigated. Shipping transport conditions in the Pan-Yellow Sea area, particularly Korea-China routes, were surveyed as well. A new Incheon-China container liner route was suggested as a partial remedy to some of the shipping transport problems of the Pan-Yellow Sea Area (North-East Asia). The Incheon-China Container Liner route is more efficient than Pusan and Pyungtaek Ports or the car ferry route to China in terms of transport time and expense. The transport burden indicator which includes the time and expense of transport, can be a useful tool in comparing these routes. Accordign to the transport burden indicator, the Incheon-China Container Liner route is more efficient than the Pusan, Pyungtaek, or car ferry routes. To establish a successful liner route between the ports of Inchon and China, there is a need to prepare three measures that contain short-term medium-term and long-term strategies. Furthermore, these measures should be prepared and adopted in phases, in accordance with considerations of future conditions for shipping and logistics in the Pan-Yellow Sea area.
