Assessment of Cybersecurity Risks: Maritime Automated Piloting Process
2022
A modern society is a combination of several critical infrastructures, of which international and national maritime transportation systems are essential parts. Digitalization makes it possible to increase levels of autonomy in maritime systems. It also means fully existing cyberenvironments in maritime processes. In cyberenvironments, it is crucial there is trustable information communication between system elements of the process, alongside the usability, reliability, and integrity of systems data in the operating environment. In order to develop maritime autonomy in Finland the Sea4Value / Fairway (S4VF) research program has been developed. At the first stage of the program, the main goal…
On automatic algorithm configuration of vehicle routing problem solvers
2019
Many of the algorithms for solving vehicle routing problems expose parameters that strongly influence the quality of obtained solutions and the performance of the algorithm. Finding good values for these parameters is a tedious task that requires experimentation and experience. Therefore, methods that automate the process of algorithm configuration have received growing attention. In this paper, we present a comprehensive study to critically evaluate and compare the capabilities and suitability of seven state-of-the-art methods in configuring vehicle routing metaheuristics. The configuration target is the solution quality of eight metaheuristics solving two vehicle routing problem variants.…
