Although decisions at the U.S. port-of-entries take into consideration many factors and stakeholders like government, citizens, travelers, security is their main priority. Officer's decision relies on letting someone into the country or forbids their entrance if they present some threat. They are trained to detect criminals, but little focus is given to identify possible victims. This thesis presents a model that finds an optimal policy regarding how many travelers are going to be conducted to further screening to better detect human trafficking victims. A Bayesian Decision Model was developed and the estimation of costs for the different possible outcomes and scenarios were made and compared. Human trafficking costs and the POE operation were considered. Results showed that decisions were affected by the human trafficking and POE operation costs, as well as the expected number of victims at the border.
