Quantifying and Minimizing Perception Gap in Social Networks
Hemant Kumar Gehlot, Mohammad Shirzadi, Junhao Gan +1
Social media has transformed global communication, yet its network structure can systematically distort perceptions through effects like the majority illusion and echo chambers. We…
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…
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…
Optimal Policies for Recovery of Multiple Systems After Disruptions
Hemant Gehlot, Shreyas Sundaram, Satish V. Ukkusuri
We consider a scenario where a system experiences a disruption, and the states (representing health values) of its components continue to reduce over time, unless they are acted up…
Joint modeling of evacuation departure and travel times in hurricanes
Hemant Gehlot, Arif Mohaimin Sadri, Satish V. Ukkusuri
Hurricanes are costly natural disasters periodically faced by households in coastal and to some extent, inland areas. A detailed understanding of evacuation behavior is fundamental…
User equilibrium with a policy-based link transmission model for stochastic time-dependent traffic networks
Hemant Gehlot, Satish V. Ukkusuri
Non-recurrent congestion is a major problem in traffic networks that causes unexpected delays during travels. In such a scenario, it is preferable to use adaptive paths or policies…
An optimal control approach of day-to-day congestion pricing for stochastic transportation networks
Hemant Gehlot, Harsha Honnappa, Satish V. Ukkusuri
Congestion pricing has become an effective instrument for traffic demand management on road networks. This paper proposes an optimal control approach for congestion pricing for day…
