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, where: the non-graphical model dependency information specifies an order in which at least some of the evaluatable components are evaluated, the model includes a visual representation that remains unchanged when the non-graphical model dependency information is added, the model supports a first variation in which the evaluatable components are evaluated in a first order when the graphical model is evaluated, the model supports a second variation in which the evaluatable components are evaluated in a second order when the graphical model is evaluated, and the first order differs from the second order; accessing additional non-graphical model dependency information, where: the additional non-graphical model dependency information allows a determined order of evaluation for the evaluatable components when the graphical model is evaluated; and storing the graphical model with the non-graphical model dependency information in a storage.
