At INFORMS–ALIO 2019, attendees will exchange ideas on classic topics covered by OR/MS and Analytics such as services, logistics and transportation, and supply chain management, as well as the new challenges brought by the increasing availability of data and its potential application to nontraditional areas such as environment, healthcare systems, sports, and disaster management. The academic meeting program will consist of parallel sessions, plenary talks, and tutorials covering different aspects of OR/MS and Analytics and will offer a forum for intellectual exchange between participants of all the countries of North and South America, as well as from other regions around the world.
