1. In a computational device, a method for providing non-graphical dependency information in a graphical modeling environment, the method comprising: providing a graphical model in a graphical modeling environment, the model comprising one or more evaluatable components; adding non-graphical model dependency information to the graphical model, the non-graphical model dependency information specifying an order in which at least some of the components are evaluated, wherein the components can be evaluated in more than one order during an evaluation of the graphical model, the model including a visual representation, the visual representation remaining unchanged when the non-graphical model dependency information is added; requesting additional non-graphical model dependency information when the components can be evaluated in more than one order, where the additional non-graphical model dependency information ensures one unique order; and storing the graphical model with the non-graphical model dependency information in a storage.
