Den 23/6 kl 11.00-12.00 hålls ett seminarium vid CenCIP inom ämnesområdet kritisk infrastruktur. Talare är Associate Professor Kash Barker från University of Oklahoma, USA, som under sin presentation fokuserar på en resiliensorienterad modell för återställnings av samberoende tekniska infrastrukturer. Under seminariet kommer det även finnas möjlighet att diskutera forskning inom det viktiga området skydd av samhällsviktig verksamhet. Seminariet är anordnat av Jonas Johansson inom ramen för CenCIP i ett led för utökat samarbete med USA rörande kritisk infrastrukturforskning. Nedan återges mer detaljerad information på engelska.
A Resilience-Driven Restoration Model for Interdependent Infrastructure Networks
Abstract: Critical infrastructure networks (e.g., electric power, water distribution) provide services that are essential for the continuous functioning of modern society. Most of these networks rely on one another to be functional. Hence, such interdependence in performance makes them highly vulnerable to a disruptive event (e.g., common failure, terrorist attacks, natural disasters), making their restoration a more challenging task. In this work, we study the restoration problem of interdependent infrastructure networks following a disruption event, proposing a resilience-driven multi-objective restoration model using mixed-integer programming that aims to maximize the resilience of the interdependent infrastructure networks while minimizing the total cost associated with the restoration process. The restoration model considers the availability of limited time and resources and provides a prioritized list of components to be restored, along with assigning and scheduling them to the available work crews. We explore disruptive scenarios with differing characteristics.
