RESUMO

The coordination of interdependencies among activities in collaborative environments is a very important and difficult task. This work defines a group of interdependencies that frequently occurs among collaborative tasks and presents a set of coordination mechanisms for the specification and control of interaction among these tasks. These mechanisms are generic and can be reused in several collaborative environments, such as interorganizational workflows and collaborative virtual environments. The separation between activities (tasks) and dependencies (controlled by the coordination mechanisms) allows the use of different coordination policies in the same collaborative environment by changing the coordination mechanisms. These mechanisms are modeled using Petri nets, which have a strong theoretical support for analysis and simulation of the collaborative environment s behavior. Using the Petri nets based model, it is possible to anticipate and test the behavior of a computer supported collaborative system even before its implementation
