Network Science in Yalta, Ukraine and Keynote

After the International Conference on Computational Management Science in Vienna, Austria, I will be off to give a keynote talk at the 3rd Yalta Optimization Conference, which will take place in Yalta, Ukraine, at the beginning of August. The theme of this year's Yalta conference is Network Science. Of course, this scientific conference should not be confused with the famous historic Yalta Conference of 1945!

I am looking forward to seeing this very scenic location on the Black Sea and to practicing both my Ukrainian and Russian. Plus, it will be great to reconnect with wonderful colleagues and friends there and to listen to the talks. Special thanks to the organizers: Professors Butenko, Prokopyev, and Shylo, for letting me deliver the keynote talk with title and abstract below.

Title: Fragile Networks: Identifying Vulnerabilities and Synergies in an Uncertain Age

Abstract: The growing number of disasters globally has dramatically demonstrated the dependence of our economies and societies on critical infrastructure networks. At the same time, the deterioration of the infrastructure from transportation and logistical networks to electric power networks due to inadequate maintenance and development as well as to climate change, has resulted in large societal and individual user costs. This talk will focus on recently introduced mathematically rigorous and computer-based tools for the assessment of network efficiency and robustness, along with vulnerability analysis. The analysis is done through the prism of distinct behavioral principles, coupled with the network topologies, the demand for resources, and the resulting flows and induced costs. The concepts will be illustrated in the context of congested transportation networks, supply chains under disruptions, financial networks, and dynamic networks such as the Internet and electric power networks. We will further explore the connections between transportation networks and different network systems and will quantify synergies associated with network integration, ranging from corporate mergers and acquisitions to collaboration among humanitarian organizations.
