According to the National Program for the Promotion of Audiovisual Creativity 2017-2021 one of the main goals is to encourage film literacy and the development of the audience, whereby film festivals have a significant role. Media literacy is the imperative of the digital age, and is now classified into a group of fundamental functional literacy along with IT, information, digital and financial, and as such is defined by the 2014 Education, Science and Technology Strategy of the Croatian Parliament. In 2009 The Film-Creative Studio Association VANIMA was founding, and since 2010 has been organizing VAFI - International Children and Youth Animation Film Festival, which is today the VAFI & RAFI festival. The festival has an emphasis on the film-making of children and youth with the aim of encouraging media literacy. An animated film festival falls into complex systems in which along a multitude of entities with attributes a continuous interaction between them takes place. With the development of a model other than foresight and forecasting, a potential bottleneck of the system can be detected thus preventing the deadlocks. Conceptualization and parameterization have provided a model which enables optimization of complex system of children and youth creativity through VAFI & RAFI - International Children and Youth Animation Film Festival.
