This paper presents a dynamic-economic model analyzing the fluctuation of container freight rate due to the interactions between the demand for container transportation services and the container fleet capacity. The demand for container transportation services is derived from international trade and is assumed exogenous. The container fleet capacity increases with new orders made two years ago,...

This paper studies the optimization of container shipping network structures and its operations under changing cargo demand and freight rates. Most existing studies that use a given matrix of average demand have not been able to deal with practical issues such as empty container repositioning, ship-slot allocating, ship sizing, and container configuration. In this paper, these issues are simult...

This paper presents a component-based software architecture that enables a container terminal to optimize their energy demand and the flexibility of this demand. This flexibility is gained from using energy-intensive battery-powered Automated Guided Vehicles (AGVs) for container transport within the terminal. While Demand Response strategies are known and already applied in some industrial bran...

In this paper, empty container movements in the Los Angeles and Long Beach (LA/LB) port area are studied in an effort to reduce congestion by optimizing the empty container reuse. The dynamic empty container reuse is modeled analytically, and techniques are developed to optimize empty container operations. Several case studies based on current and projected demand in the LA/LB port area are use...

The dramatic increasing of sea-freight container transportations and the developing trend for using containers in the multimodal handling systems through the sea, rail, road and land in the present market cause some challenges to the general managers of container terminals such as increasing demand, competitive situation, new investments and expansion of new activities and the need to use new m...

Being aimed at the influence of ship-size and cargo-demand changes on container shipping networks, to reveal the evolution process of container shipping networks structure form, this paper respectively designed the operation models for two major container shipping networks structure forms: Multi-port-calling network and Hub-and-spoke network, to maximizing the investment efficiency. Based on th...

This paper deals with a realistic multi-period liner ship fleet planning problem by incorporating stochastic dependency of the random and period-dependent container shipment demand. This problem is formulated as a multi-period stochastic programming model with a sequence of interrelated two-stage stochastic programming (2SSP) problems characterized ship fleet planning in each single period. A s...

As a typical discrete element dynamic system (DEDS), railway container hub scheduling system has the characteristic of high randomness, low flexibility, uncertainty of operation time and high coordination demand of facilities. In this paper, according to the analysis of layout, establishment, facility and operation procedure of railway container hub, we choose Multiagent systems (MAS) which hav...
