Optimal unlabeled set partitioning with application to risk-based quarantine policies

J Lin, H Aprahamian, H El-Amine - IISE Transactions, 2024 - Taylor & Francis
We consider the problem of partitioning a set of items into unlabeled subsets so as to
optimize an additive objective, ie, the objective function value of a partition is equal to the …

An optimization-based framework to minimize the spread of diseases in social networks with heterogeneous nodes

S Li, H Aprahamian - IISE Transactions, 2024 - Taylor & Francis
We provide an optimization-based framework that identifies social separation policies to
mitigate the spread of diseases in social networks. The study considers subject-specific risk …

Set Partitioning: Applications in Health Care

H Aprahamian, H El-Amine - Encyclopedia of Optimization, 2022 - Springer
The set partitioning problem (SPP) is the task of partitioning a finite set of items in a manner
that optimizes a certain objective function. For a given finite set made up of N∈ N+ items …

Capturing the dilution effect of risk‐based grouping with application to COVID‐19 screening

S Chatterjee, H Aprahamian - Naval Research Logistics (NRL), 2022 - Wiley Online Library
We investigate the problem of screening a large population for an infectious disease (ie,
classifying subjects as positive or negative) using group testing while considering important …
