The Section on Public and Societal Operations Research (PSOR) is dedicated to advancing operations research (O.R.) and management science (MS) to address critical public sector and societal challenges. The section brings together researchers, practitioners, educators, lived experts, and policymakers committed to improving our world and society by ethically and responsibly leveraging analytical methods, data-driven decision-making, and mathematical modeling to drive impact. PSOR encompasses a wide range of societal issues, including community development, humanitarian logistics, refugee resettlement, human trafficking, affordable housing, climate change, economic inequality, nonprofit operations, and more. Through conferences, publications, and professional networking, PSOR serves as a central hub for knowledge exchange and best practices in applying OR/MS to public and societal challenges.
