In container terminals, one of the most important factors driving the logistic efficiency in the yard is stowage planning for containers designated to be exported. The stowage plan and operations have to meet the requirement of the liner shipping company of ship stability on the one hand, and to ensure the smooth and orderly process of handling containers, deployment and movement of the yard cr...

Since a ship yard usually provides insufficient data for developing a ship control system, the course and track controller design is based upon a Nomoto model determined with a Clarke estimation of hydrodynamic derivatives. Several ships examined show a poor system performance with a course control derived from these models besides parameter identification problems of adaptive control concepts....

Singapore has one of the busiest ports in the world. Ship berthing is one of the problems faced by the planners at the port. In this paper , we study the ship berthing problem. We first provide the problem formulation and study the complexity of the problem with different restrictions. In general, the ship berthing problem is NP-complete, although, some of its variants may be solved quickly. Wh...

The efficiency of a maritime container terminal primarily depends on the smooth and orderly process of handling containers, especially during the ship s loading process. The stowage and associated loading plans are mainly determined by two criteria: ship stability and the minimum number of container rehandles required. The latter is based on the fact that most container ships have a cellular st...

This paper presents the algorithm for target point detection using image based methods and sensor networks to monitor the accuracy control for assembling ship blocks in a ship yard area. Dimensional control of the product at all assembling level accounts for a profitable ship production. An accuracy error at each stage accumulates to a higher value which leads to low level of ship productivity....

Seaport container terminals are an important part of the logistics systems in international trades. This paper investigates the relationship between quay cranes, yard machines and container storage locations in a multi-berth and multi-ship environment. The aims are to develop a model for improving the operation efficiency of the seaports and to develop an analytical tool for yard operation plan...

In recent years, the number of shipping containers grows rapidly, and in many container yard terminals, increasing throughput of material handling operation becomes important issue as well as decreasing the turnaround times of vessels. Material handling operations for loading containers into a vessel is highly complex, and the complexity grows at an exponential rate according to the growth of t...
