Abstract The modelling process consists of a series of abstraction levels deriving a formulation suitable for the solution process from observations of the real system. A relational view is typical for the real system. By applying it to the target formulation a shift of the application of conceptual knowledge from the modeller to the computer becomes possible. The general methodology is shown at linear optimization models and mixed integer models. Furthermore this approach is compared with recent modelling aids, such as matrix generators and modelling languages, and the advantages of this approach especially with respect to the model life cycle are shown.
