A novel supply chain network evolving model under random and targeted disruptions

Due to the fact that there is a lack of comprehensive understanding of how the dynamic nature of supply chain networks (SCNs) interrelates with network structures, particularly network topologies under disruptions. This research employs a novel evolving model of a supply chain network (SCNE model) by modifying the Barabási and Albert (BA)...

Dynamic model-based method for the analysis of ship behavior in marine traffic situation

With the continual development of modern transportation technology and artificial intelligence technology, how to recognize the complex phenomenon of ship behavior existing in maritime traffic has become a hot topic. Maritime traffic is a complex system, the emergence of ship behavior is a leading cause of traffic complexity, and make up the...

On the application of the window of opportunity and complex network to risk analysis of process plants operations during a pandemic

To quantify the pandemic specific impact with respect to the risk related to the chemical industry, a novel risk analysis method is proposed. The method includes three parts. Firstly, the two types of “window of opportunity” (WO) theory is proposed to divide an accident life cycle into two parts. Then, a qualitative risk analysis is conducted...

Exploring the topology of the maritime transport network in a large-scale archipelago: a complex network approach

In this study, we use a complex network analysis approach to investigate the topological structure of container shipping networks in the Indonesia archipelago to understand the network topology. Containerized cargo is responsible for more than half of the inter-island trade volume, making it one critical freight transport mode in the Indonesia...

Cascading failure of nodes and their links in a complex network

Cascading Failure has become one of the points of scientific research in complex networks. In this paper, we use the different definition of Load and Capacity in the network, to research the final changing direction of Cascade model with an attack. When the node Capacity is within a specific range, Risk Strength and Elasticity of the link both...
