“…The results of numerical experiments presented in [14] demonstrated that a dual cycle for internal trucks in the yard area can reduce the transportation distance of containers, and that the space allocation method based on this strategy was more effective than traditional methods. The simulations conducted in [15] confirmed a notable improvement in regard to maximising productivity and minimising hourly and unit costs; however, the higher usage of QCs has been found to contribute to an increase in their highest observed peak power demand, leading to higher energy-related costs, as discussed in [16].…”

The primary objective of this research was to implement a more efficient handling strategy in the container terminal storage yard at the Baltic Hub Container Terminal (BHCT). Following an analysis of the current logistics system associated with starboard-side mooring, an attempt was made to shift the mooring to the port side. Two routing strategies corresponding to the analysed mooring operations were tested using a developed model. Simulations were conducted to enable a comparison of various handling strategies that were suitable for the mooring arrangements and equipment under investigation. This analysis was based on reliable information obtained from a real process. Evaluative criteria for examining the impact of changing the handling strategy of internal movement vehicles (IMVs) in the terminal storage yard in terms of process efficiency included the total time and distance of container transportation and the truck utilisation level. A new route for IMVs was developed to accommodate the changed mooring operation. This adjustment aimed to enhance the discharge process and to reduce the distance travelled, resulting in a reduction in fuel consumption. The shorter travel distance also positively impacted productivity, and contributed to a reduction in operating costs. The changes to the mooring arrangement directly resulted in a 10% increase in the quay crane gross productivity, measured in moves per hour (mph). Given that many ports do not pay attention to how ships are moored, the case study and analysis presented here can help staff quickly improve their handling strategy and productivity, thus increasing the port’s competitiveness.

“…Yard trucks (YTs) are used to transport containers between the berth and a storage yard (SY), and scheduling of these yard trucks is a logistic problem inherent in seaport container terminals. The more trucks that move within the same time, the more likely it is that traffic congestion could arise, which would cause delay in the truck cycle time [3], and ultimately results in shipping delays and delay in delivery of trade goods. Delivery operations can take long hours due to congestion [4] at container terminals.…”

This paper presents significant measures to tackling berth occupancy and quay-yard operation problems. Case study was conducted on a port container terminal in Nigeria confidentially identified as ‘Port A’ in this paper. Hungarian assignment algorithm was used to reduce the total travel time of the yard trucks from an average of 6.4 minutes to 3.5minutes, while M/M/c/K queuing model was applied in scheduling the quay crane assignments. Results showed tremendous increase in quay crane rate, berth capacity and improved berth utilization. Also, for the reach stacker, the crane rate can be improved to 30 TEUs/hr at berth occupancy below 0.40 with TEUs factor of 1.4. These results imply that for Nigeria terminals operating with reach stacker crane, it is possible to improve the berth capacity without affecting the berth utilization of the terminal.

The development of simulation models is believed to have an impact on the quality of the models produced (Ericksson (2003)) Ahmed and et al (2014). found a lack of material to guide the software process simulation model in producing a software process simulation model, which is why he developed a framework and a guideline for the simulation modeling process Ahmed and et al (2014).…”

This study analyzed an automated system of container operations at Laem Chabang Port, Thailand. Due to the rapid growth in demand at the port, the throughput volume cannot reach the requirement, has difficulty in unskilled worker recruitment, working hours are limited, and has limitation on the terminal area. Therefore, an automated system is planned to replace the conventional container operations; this will also support the Port Authority of Thailand's encouragement of using automation technology. Along with the increasing the level of port development and enhancement of the container terminal port to be competitive in the world trade arena by developing and managing infrastructure and facilities to meet world-class standards. This study assumes an automatic system for container handling through the combination of machines, i.e., a semi-automated ship-to-shore gantry crane, an automated rubber-tired gantry crane, and an automated guided vehicle for the container movement. The specification of machines was obtained from the existing available technology in the marketplace. The data collected from the literature performance evaluation of container port outputs is simulated using ARENA software. The analysis showed that the automated system could improve operations in many aspects such as berth occupancy, ship waiting time, ship turnaround time, machine utilization, and resulting in much better container throughputs. Lastly, this paper summarizes the port's main advantages and challenges if the automated system is implemented.
