Abstract Due to the increase in digitalization on board ships, potential consequences of a cyber-induced incident can threaten safety ships. A known challenge maritime industry is communication between ship owner management onshore and crew ship, especially during handling. To mitigate this issue enhance cooperation digital age, need meet, train for, discuss cyber risks their challenges. One wa...

The problem of multiagent patrol has gained considerable attention during the past decade, with the immediate applicability of the problem being one of its main sources of interest. In this paper we concentrate on frequency-based patrol, in which the agents’ goal is to optimize a frequency criterion, namely, minimizing the time between visits to a set of interest points. We consider multiagent ...

This paper presents a formalism called Time Interval Petri Nets (TIPNs), which are designed to support a qualitative simulation of temporal concurrent processes. One of the key features of TIPNs is a uniform use of time intervals throughout the model. This enables a natural and efficient representation of temporal uncertainty in inputs, outputs, and intermediate states of the qualitative simula...

This paper deals with a method of studying the profitability of a maritime line under the service of a specific ship when the data describing the sea state along it are available only for a short period of time or are missing. As a specific example, the line Piraeus Heraklion at Aegean Sea is considered, where wave data are available for a very short period (3 years). The method developed is ba...
