Handling Disruptions in Supply Chains: An Integrated Framework and an Agent-based Model

The degree of supply chain risk faced by many companies has risen dramatically and the impact of disruptions can cascade easily across companies’ and countries’ borders. To handle this increased vulnerability, systematic approaches and decision making tools are needed to provide support in managing supply chain disruptions. In this thesis, an...

A consolidation model for cargo-driven intermodal transportation

Accessibility of main sea ports by road has become increasingly difficult due to rapid growth in container throughput. To deal with this challenge, new ways for handling containers and distribution of cargo flows are needed to define and implement. One possibility is going beyond container transportation and considering cargos inside the...

Multimodal schedule design for synchromodal freight transport systems

Intermodal freight transport has been discussed for decades as an alternative to unimodal road transport. However, it still does not represent a significant portion of the total freight market. A new and promising possibility to improve the performance of freight systems is the synchromodal design of hinterland transport systems. A...

European intermodal freight transport network: Market structure analysis

The analysis of market structure and concentration measures for the Intermodal Freight Transport (IFT) market is important to avoid market failure and to find the areas for policy making to promote IFT market share. This analysis can be performed for separate segments, for example, the market for transshipment service or the market for main...

Analyzing competition in intermodal freight transport networks: The market implication of business consolidation strategies

To cope with an intense and competitive environment, intermodal freight transport operators have increasingly adopted business practices —like horizontal and vertical business integration—which aim to reduce the operational costs, increase the profit margins, and improve their competitive position in the market. These strategies and business...

A review and analysis of the investment in, and cost structure of, intermodal rail terminals

The results presented in this article identify the role of costs in the scientific and grey freight terminal handling literature and analyses the handling costs of different terminal sizes. The literature review shows that handling costs only play a marginal role in the scientific research in intermodal rail freight terminals (IRT). This is...

Communication between deep sea container terminals and hinterland stakeholders: information needs and the relevance of information exchange

Hinterland container transport is increasingly identified as an important element in door-to-door transportation of goods in the context of global supply chains. Container terminal operators also continuously seek strategies to distinguish themselves from their competitors by providing dedicated information on containers, transport means and...

Probabilistic analysis of switching transients due to vacuum circuit breaker operation on wind turbine step-up transformers

Vacuum circuit breaker operation causes transient overvoltages that may lead to severe damages to transformer insulation. Since the parameters affecting these overvoltages have stochastic nature, a statistical analysis may provide detailed insight into the overvoltages from the point of view of insulation coordination applications. In this paper...

Experimentally Validated Extended Kalman Filter Approach for Geomagnetically Induced Current Measurement

Geomagnetically induced currents (GICs) are referred to the quasi-DC current flows in power networks, driven by complex space weather-related phenomena. Such currents are a potential threat to the power delivery capability of electrical grids. To mitigate the detrimental impacts of GICs on critical infrastructures, the GICs should be monitored...

Shunt Capacitor Bank Fault Detection and Localization Using Sub-Cycle Algorithm

Fast internal detection and location in Shunt Ca-pacitor Banks (SCBs) can lead to the prevention of damages to other SCBs' elements and consequently avoid undesirable performance and effects in power system operation. This paper targets the performance of phasor-based algorithms of failure detection and fault location of SCBs. Being dependent on...

Innovative Solid-State Ferroresonance-Suppressing Circuit for Voltage Transformer Protection in Wind Generation Systems

Ferroresonance, as an undesirable disturbance, leads to significant overvoltage and distorted waveforms. This phenomenon can be highly damaging to voltage transformers and other parallel-connected equipment and can entail catastrophic consequences. This paper aims to design and study a solid-state ferroresonance-suppressing circuit (SSFSC) to...

Multifaceted Functionalities of Bridge-Type DC Reactor Fault Current Limiters: An Experimentally Validated Investigation

With the ongoing expansion and interconnection of electrical power systems, alongside the rapid proliferation of renewable distributed generations (DGs), the short-circuit extent in the power grid is experiencing a significant rise. Fault current limiters (FCLs) have been introduced in an effort to address this issue, ensuring the robustness and...
