  • With increase in container traffic, there has been constant shortage in supply of containers causing upward tendency at a price of sale and lease. In this point of view, it is safe to say that the importance of demand and supply management for containers is getting dear. At the same time, growing dependence on leasing containers has huge effect on increase in cost because of the difficulty in forming forecast model.

  • In addition to recession, world shipping companies are undergoing restructuring due to excess of "World Container Cargo volume" per "World Containership capacity" (in TEU terms). This excess is attributed to the absence of standard index of calculating the "World Containership capacity" (in TEU terms) for "World Container Cargo volume." The purpose of this study is to develop indices and terms: "World Containership capacity (in TEU terms) Standards Index; WCSI" and "World Containership capacity (in TEU terms) Expected Index; WCEI." The comparison between "WCSI" and "WCEI" made in this study is presented below. WCSI (Average voyage 9.3) > WCEI Excess shipping (in TEU terms) WCSI (Average voyage 9.3) = WCEI Optimum shipping (in TEU terms) WCSI (Average voyage 9.3) < WCEI Short shipping (in TEU terms) WCSI=HRCI $1000{\pm}150$ Value approx. The study shows that it is possible to predict "optimal supply of the world's containership capacity" (in TEU terms), "excess or shortage of shipping" (in TEU terms), "order time of container-ship capacity building" (in TEU terms), "order quantity of containership capacity" (in TEU terms), and "stable of World Shipping Companies" by "WCSI" and "WCEI." The development of "WCSI" and "WCEI" aim to help overcome the crisis of recession by establishing effective business strategies for world shipping companies and their supporting companies.

  • Due to the increase in container cargo volume, the congestion of container terminals is increasing and the waiting time of gate in-out trucks has significantly lengthened at container yards and gates, resulting in severe inefficiency in gate in-out truck operations as well as port operations. To resolve this problem, the Busan Port Authority and terminal operator provide services such VBS, terminal congestion information, and expected operation processing time information. However, the visible effect remains insufficient, as it may differ from actual waiting time.. Thus, as basic data to resolve this problem, this study presents deep learning based average gate in-out truck waiting time prediction models, using container gate in-out information at Busan New Port. As a result of verifying the predictive rate through comparison with the actual average waiting time, it was confirmed that the proposed predictive models showed high predictive rate.

  • This study analyzes the dynamic characteristics of cargo volume (demand), ship fleet (supply), and freight rate (price) of container, dry bulk, and tanker shipping markets by using the VAR and VECM models. This analysis is expected to enhance the statistical understanding of market dynamics, which is perceived by the actual experiences of market participants. The common statistical patterns, which are all shown in the three shipping markets, are as follows: 1) The Granger-causality test reveals that the past increase of fleet variable induces the present decrease of freight rate variable. 2) The impulse-response analysis shows that cargo shock increases the freight rate but fleet shock decreases the freight rate. 3) Among the three cargo, fleet, and freight rate shocks, the freight rate shock is overwhelmingly largest. 4) The comparison of adjR2 reveals that the fleet variable is most explained by the endogenous variables, i.e., cargo, fleet, and freight rate in each of shipping markets. 5) The estimation of co-integrating vectors shows that the increase of cargo increases the freight rate but the increase of fleet decreases the freight rate. 6) The estimation of adjustment speed demonstrates that the past-period positive deviation from the long-run equilibrium freight rate induces the decrease of present freight rate.

  • This paper qualitatively describes logistics behaviors of 113 companies located in Daegu-Gyeongbuk by considering various characteristics such as business location, trade volume, cargo types and the possession of company's own warehouse. A logit model is developed to investigate how predictor variables affect these companies' inclination of utilizing Third Party Logistics Provider(3PL). The estimation results of 102 effective data points show that among the four predictors the location of company's HQs (HQADD) and trade volume (TRDTEU) significantly increase company's tendency towards utilizing 3PL while the remaining two variables (BULK, WAREHS) imparting statistically insignificant influence. The results indicate that those companies located outside the region tend to implement a strategy of using more 3PL and also that the larger the trade volume of the company the more 3PL the company uses to improve the efficiency in logistics.

  • Over the past 20 years, Korea's overall import and export cargo volume has increased at an average annual rate of approximately 5.3%. About 99% of the cargo is still being transported by sea. Due to recent increases in maritime cargo volume, congestion in maritime logistics has become challenging due to factors such as the COVID-19 pandemic and conflicts. Continuous monitoring of ports has become crucial. Various ground observation systems and Automatic Identification System (AIS) data have been utilized for monitoring ports and conducting numerous preliminary studies for the efficient operation of container terminals and cargo volume prediction. However, small and developing countries' ports face difficulties in monitoring due to environmental issues and aging infrastructure compared to large ports. Recently, with the increasing utility of artificial satellites, preliminary studies have been conducted using satellite imagery for continuous maritime cargo data collection and establishing ocean monitoring systems in vast and hard-to-reach areas. This study aims to visually detect ships docked at berths in the Busan New Port using high-resolution satellite imagery and quantitatively evaluate berth utilization rates. By utilizing high-resolution satellite imagery from Compact Advanced Satellite 500-1 (CAS500-1), Korea Multi-Purpose satellite-3 (KOMPSAT-3), PlanetScope, and Sentinel-2A, ships docked within the port berths were visually detected. The berth utilization rate was calculated using the total number of ships that could be docked at the berths. The results showed variations in berth utilization rates on June 2, 2022, with values of 0.67, 0.7, and 0.59, indicating fluctuations based on the time of satellite image capture. On June 3, 2022, the value remained at 0.7, signifying a consistent berth utilization rate despite changes in ship types. A higher berth utilization rate indicates active operations at the berth. This information can assist in basic planning for new ship operation schedules, as congested berths can lead to longer waiting times for ships in anchorages, potentially resulting in increased freight rates. The duration of operations at berths can vary from several hours to several days. The results of calculating changes in ships at berths based on differences in satellite image capture times, even with a time difference of 4 minutes and 49 seconds, demonstrated variations in ship presence. With short observation intervals and the utilization of high-resolution satellite imagery, continuous monitoring within ports can be achieved. Additionally, utilizing satellite imagery to monitor changes in ships at berths in minute increments could prove useful for small and developing country ports where harbor management is not well-established, offering valuable insights and solutions.

  • As competition in domestic and overseas ports intensify, new and small domestic ports are realizing certain limitations to independently secure competitiveness. This study collected data over 60 months with five modifications for container and general cargo volume around Gyeongin Port. Short-period (12 months) cargo volume was forecasted, which revealed the need for a middle-to-long-term development plan. First, the hinterland logistics complex of Gyeongin Port is expected to contribute to the coastal maritime facility through the quasi-public system for fishery product transportation and passenger services. It proposes to achieve this by opening channels to and from China for precision machinery, home network systems, LEDs, and machine industry items. second, specializing the ultra-light cargo transport route, and connecting the coastal island areas of the 5 West Sea Islands to Ara Waterway (Integrated Fishery Product Center of the 5 West Sea Islands). Third, on the basis of organic cooperation of government? local government ? port, the incentive and pre-circular support system would be required, and lastly, it shall carry out the adjustment of functions in nearby ports and specialization strategy simultaneously through the integrated operation of the ports in the capital areas.
