  In 2020 tens of millions of migrants worldwide sought safety due to various
push-pull factors such as economic, geographic, demographic, and societal
challenges. Large movements of human flows toward national borders constitute a
complex humanitarian crisis that requires appropriate preparations of border
resources. Motivated by prevailing national agenda issues for improved border
support, we identify common operational challenges along the border and discuss
how they can be addressed using advanced analytics. Multiple stakeholders,
corresponding goals, and complex decisions call for advanced optimization
techniques to holistically treat such challenges. This chapter highlights how
optimization can be employed to improve both the security and humanitarian
aspects of border operations in the context of migration flows.
