Path Location Problem for the Container Terminal with Yard Arrangement Efficiency Comparatively new terminal in Japan uses reclaimed land in most cases, in order to secure water depth of the quay. However, the terminals in other countries have various configurations. This study considers the problem to optimize the container block size in the storage area of container terminal with a given shape. Since the path where is located vertical to quay line influence handling efficiency, this study considers it as a problem which finds path location. In order to investigate the effects of the ship arrival pattern and the number of containers handled, it is evaluated by the total service time. From the computational results, in irregular and rectangular shapes, the total service time obtained by the proposed approach can be less than that time at the path arranged in same intervals.

Transshipment operations optimization of searail intermodal container in seaport rail terminals Abstract   This paper tackles the searail transshipment operation problem of seaport rail terminals, which includes two key subproblems involved in searail intermodal container transportation, namely train schedule template and transshipment plan of inbound containers. With limited resources and time constraints, operators need to decide the placedin and takenout time of trains to coordinate with vesselsxe2x80x99 unloading time and the transshipment plan of inbound containers (i.e. the amount of containers that are transshipped between different vessels and trains in each time slot) to maximize the number of directtransshipment containers while minimizing the storage time and dwell time of inbound containers. The problem is formulated as an integer programming model, and a tailored rolling horizon approach with the adaptive horizon and backtracking strategy is proposed. The performance of the algorithm is verified by a set of instances. The results suggest that the handling capacity of railmounted gantry cranes shows a more significant effect on the performance of transshipment operation than other factors. The negative effect caused by insufficient handling capacity could be alleviated by methods like prolonging the feasible service time of trains and enhancing the operational capacity of shunting engines.
