Minimizing the Risk of Spreading Processes via Surveillance Schedules and Sparse Control

Epidemics, computer viruses and bushfires can all be
thought of as spreading processes in which an initial
localized outbreak spreads rapidly to neighbouring nodes
and throughout a network. The real-world risks associated
with these events have sparked significant research into
methods for modelling, prediction, and control.
In this talk, we propose an optimisation framework that
combines surveillance schedules and sparse control
to bound the risk of spreading processes. Here, risk is
considered the product of the probability of an outbreak
and the impact of that outbreak. We can bound or
minimise the risk by resource allocation and persistent
monitoring schedules. The presented framework utilises
the properties of positive systems and convex optimisation,
in particular exponential cone programming, to provide
scalable algorithms. We demonstrate how the method
can incorporate different parameters and scenarios, such
as a vaccination strategy for epidemics and the effect of
vegetation and weather for bushfires.

Vera Somers is a PhD candidate at the Australian Centre
for Field Robotics at the University of Sydney. She received
the BSc and MSc degrees in Aerospace Engineering from
Delft University of Technology, the Netherlands. She was
a Research Assistant with the Humans and Autonomy Lab
at Duke University, USA. Her research interests include
control, simulation and optimisation of complex networks
and spreading processes.
