The Brazilian Air Force's mission is: "Maintain the sovereignty of the airspace and integrate the national territory, with a view to the defense of the country boundaries" (Brasil, 2018, p. 20). To achieve this mission, the Brazilian Air Force needs the readiness to employ means that are part of complex systems limited in resources. Thus, it is necessary to use such resources most efficiently.Air Forces operations are intrinsically complex. This affirmation drives to constant development and improvement of all the readiness structures. To achieve this goal Brazilian Air Force has a tool called Operational Assessment (represented by acronym AVAOP), and Readiness Command is accountable for it. This command has subordinated units, where the operational resources are prepared and trained. One of them, responsible for performing AVAOPs, is the Institute of Operational Applications, based at Sao Jose dos Campos, Sao Paulo state. At that institute, "the staff is trained and skilled in solving complex problems and generating solutions with mathematical models and programming, statistics, and stochastic processes". (Brasil, 2019, p. 2).
