Organizing Public Security during international sports events with LaSca

摘要

Decision-making involves choosing between one or more alternatives, to achieve one or more goals. To support this process, there are decision support systems that employ different approaches, supporting groups or not. Generally, however, these systems do not have great flexibility; their users have to follow preestablished decision methods. This paper, then, briefly addresses LaSca, a decision support system that employs different approaches in supporting large groups, for the benefits its use presents in decision-making processes, in their problem and solution discussing, alternatives generation and group choosing process, this way letting its users to also decide how to decide. Then, it presents the system's last improvements. Finally, this work discusses how the LaSca system could help design a great sports event such as the upcoming 2016 Olympic games at Rio de Janeiro with the aid of large groups, using the organization of the Public Security schema of the Panamerican Championship of Artistic Gymnastics, that happened in November 2009, in Aracaju, Brazil, as an example.
