Abstract The ever increasing demand for container transportation has led to the congestion of maritime terminals in world. In this work, two interrelated problems berth and quay crane scheduling are considered an integrated multiobjective mathematical model. A special character model is that arrival times vessels failure (working) cranes not deterministic can vary based on some scenarios. Hence...

In this article we propose a heuristic algorithm to explore search space trees associated with instances of combinatorial optimization problems. The is based on Monte Carlo tree search, popular in game playing that used and represents the state-of-the-art for number games. Several enhancements are proposed make more suitable context. These exploit structure problem aim efficiently by pruning su...

Abstract Background In 2017, smaller container ports handled approximately 22% of total containerized cargo. Nowadays liner operators are calling on those with larger ships and demanding fast efficient turnaround the in port. This is possible only if berth has right capacities, working properly achieves a good productivity level. Methodology Productivity level does not depend quay crane capacit...

• The BAP and the Quay Cranes Assignment Problem is studied. A mixed integer linear programming model developed. An efficient construction heuristics are proposed. metaheuristic approach designed. Experimental results demonstrate effectiveness of proposal. Berth Allocation two decisive seaside operations planning problems in maritime terminals. Therefore, integrating these critical improving an...

Currently, JICT capacity 2.5 million TEUs (Twenty-foot Equivalent Units) per year, it continues to strive improve international services and supported by adequate loading unloading equipment. The requirement establish common standards different types of equipment iden...

yard crane is an important resource in container terminals. efficient utilization of the yard crane significantly improves the productivity and the profitability of the container terminal. this paper presents a mixed integer programming model for the yard crane scheduling problem with non- interference constraint that is nphard in nature. in other words, one of the most important constraints in...

The stability of the quay wall incorporating large diameter cylinders is of great concern at the Yangshan Port, China, owing to severe marine environment. In this study, finite element analysis is carried out to evaluate the stability of a trial quay wall during construction. The single cylinder is examined in terms of turnover failure subjected to a five year design wave action. The case when ...
