An Integrated Cyber-Physical Risk Assessment Framework for Worst-Case Attacks in Industrial Control Systems
Navid Aftabi, Dan Li, Ph. D. +2
Industrial Control Systems (ICSs) are widely used in critical infrastructures that face various cyberattacks causing physical damage. With the increasing integration of the ICSs an…
A Framework for Operations Research Model Use in Resilience to Fundamental Surprise Events: Observations from University Operations during COVID-19
Thomas C. Sharkey, Steven Foster, Sudeep Hegde +2
Operations research (OR) approaches have been increasingly applied to model the resilience of a system to surprise events. In order to model a surprise event, one must have an unde…
Multi-Period Max Flow Network Interdiction with Restructuring for Disrupting Domestic Sex Trafficking Networks
Daniel Kosmas, Thomas C Sharkey, John E Mitchell +2
We consider a new class of multi-period network interdiction problems, where interdiction and restructuring decisions are decided upon before the network is operated and implemente…
A Transdisciplinary Approach for Generating Synthetic but Realistic Domestic Sex Trafficking Networks
Daniel Kosmas, Christina Melander, Emily Singerhouse +4
One of the major challenges associated with applying operations research (OR) models to disrupting human trafficking networks is the limited amount of reliable data sources readily…
Optimizing Edge Sets in Networks to Produce Ground Truth Communities Based on Modularity
Daniel Kosmas, John E. Mitchell, Thomas C. Sharkey +1
We consider two new problems regarding the impact of edge addition or removal on the modularity of partitions (or community structures) in a network. The first problem seeks to add…
Interdicting Restructuring Networks with Applications in Illicit Trafficking
Daniel Kosmas, Thomas C. Sharkey, John E. Mitchell +2
We consider a new class of max flow network interdiction problems, where the defender is able to introduce new arcs to the network after the attacker has made their interdiction de…
A Synthetic Network Generator for Covert Network Analytics
Amr Elsisy, Aamir Mandviwalla, Boleslaw Szymanski +1
We study social networks and focus on covert (also known as hidden) networks, such as terrorist or criminal networks. Their structures, memberships and activities are illegal. Thus…
