Summary: This study proposes a double-cycling AGV scheduling model to minimize the total waiting time of AGVs and ensure a high loading rate. By considering the randomness of quay crane's operational time, a container scheduling sequence is obtained through a hybrid particle swarm optimization algorithm.

Summary: This study conducted a detailed simulation research on different types of layout design to compare their terminal performance. The results indicate that U-type automated terminals have the lowest energy consumption and operation cost, and outperform those with perpendicular layout in terms of operation efficiency and waiting time in most cases. The findings provide valuable reference for terminal operators to make strategic decisions.

Summary: Incentive bonus payments for terminal operators are mostly based on throughput growth rate, which may not effectively encourage their utilization of terminal facilities and equipment. This paper introduces the possibility and advantage of DEA-based incentive bonus allocations, which consider both throughput/throughput increment and production efficiency. Three DEA-based incentive bonus allocation models are proposed for different output items.

Summary: This study estimated energy consumption and CO2 emissions in container terminals based on different layouts. Results showed that parallel and perpendicular layouts have similar CO2 emissions, indicating their suitability for sustainable development in future ports. The findings can be used for future planning of operations and layout selection in container terminals.

Summary: This study analyzes the operational efficiency and total factor productivity of 32 container terminal companies in China. The research reveals the existence of efficiency gaps and resource waste in some container terminals, while highlighting the higher operational efficiency of terminals in the Bohai Rim, Pearl River Delta, and Yangtze River Delta regions. Furthermore, the study finds that most container terminal companies have imperfect management practices and decision making.

Summary: Despite high ship utilization and peak activity at import container terminals, truck congestion has led to the development of a Truck Appointment System (TAS). Numerical experiments show that a cooperative model between transport companies and terminal operators is more efficient than individual decision-making in reducing truck congestion.

Summary: This study indicates a disparity in the criteria used by shipping companies and port operators to measure port competitiveness. While port operators prioritize factors like port location and service level, shipping companies prioritize port operational efficiency. The research suggests that better mutual understanding between ports and carriers can lead to a more efficient economic system and societal development.

Summary: This study presents operational electricity consumption and greenhouse gas emissions for specific European telecom network operators during 2015-2018 and compares them to data from 2010-2015. The study finds that the electricity consumption and number of subscriptions for the reporting telecom network operators remained relatively constant, while data traffic increased significantly.
