The performance of a container terminal depends on many aspects of operations. This paper focuses on the optimal sequencing of a yard crane (or YC for short) for serving a fleet of vehicles for delivery and pickup jobs. The objective is to minimize the average vehicle waiting time. While heuristic algorithms could not guarantee an optimal solution, a conventional mathematical formulation such a...

Productivity is an extremely important factor in the competitiveness of a container terminal. itself largely influenced by handling mechanisation, main task which to serve quay cranes on one side and yard other. One most effective types mechanisation this segment shuttle carriers, are used primarily larger terminals. The objective study was determine if they can also be effectively smaller term...

The time that containerships or transportation trucks spend in marine container terminals for loading and unloading their cargo is a real cost scenario which affects, not only the smooth operation of ports, but also affect the overall cost of container trade. The operators of shipping lines and container terminals are required to realize the importance of this issue and the costs associated wit...

Container terminals play a critical role in international shipping and are under pressure to cope with increasing container traffic. The problem of managing container terminals effectively has a number of characteristics which make agents a suitable technology to consider applying. Container terminals involve the operation of distributed entities (e.g. quay cranes, straddle carriers) which coor...

Commonly in container terminals, the containers are stored in yards on top of each other using yard cranes. The split-platform storage/retrieval system (SP-AS/RS) has been invented to store containers more efficiently and to access them more quickly. The integrated scheduling of quay cranes, automated guided vehicles and handling platforms in SP-AS/RS has been formulated and solved using the si...

In a dynamic environment, it is quite reasonable to implement functions as a set of rules into an agent to react to unexpected situations, because it is very difficult to have a correct model of the environment. This paper describes a reinforcement studying method to acquire the rules, each of which consists of state and action pair, for coordinating execution of the multiple cranes in a coil-y...

The problem considered in this paper is to locate storage containers while a set of container storage and retrieval requests are sequenced. Two automated cranes stack and retrieve containers in a single block of a yard. The cranes cannot pass each other and must be separated by a safety distance. Storage containers are initially located at the seaside and landside input/output (I/O) points of t...
