Algorithms for Influence Maximization in Socio-Physical Networks
Hemant Gehlot, Shreyas Sundaram, Satish V. Ukkusuri
Given a directed graph (representing a social network), the influence maximization problem is to find k nodes which, when influenced (or activated), would maximize the number of re…
Early Warning of COVID-19 Hotspots using Mobility of High Risk Users from Web Search Queries
Takahiro Yabe, Kota Tsubouchi, Satish V Ukkusuri
COVID-19 has disrupted the global economy and well-being of people at an unprecedented scale and magnitude. To contain the disease, an effective early warning system that predicts…
Policies for Multi-Agency Recovery of Physical Infrastructure After Disasters
Hemant Gehlot, Shreyas Sundaram, Satish V. Ukkusuri
We consider a scenario where multiple infrastructure components have been damaged after a disaster and the health value of each component continues to deteriorate if it is not bein…
Control Policies for Recovery of Interdependent Systems After Disruptions
Hemant Gehlot, Shreyas Sundaram, Satish V. Ukkusuri
We examine a control problem where the states of the components of a system deteriorate after a disruption, if they are not being repaired by an entity. There exist a set of depend…
Demand-Adaptive Route Planning and Scheduling for Urban Hub-based High-Capacity Mobility-on-Demand Services
Xinwu Qian, Jiawei Xue, Satish V. Ukkusuri
In this study, we propose a three-stage framework for the planning and scheduling of high-capacity mobility-on-demand services (e.g., micro transit and flexible transit) at urban a…
Modeling disease spreading with adaptive behavior considering local and global information dissemination
Xinwu Qian, Jiawei Xue, Satish V. Ukkusuri
The study proposes a modeling framework for investigating the disease dynamics with adaptive human behavior during a disease outbreak, considering the impacts of both local observa…
