1. A method for analysis of a computer-based and data-processing model of a complex system, wherein the model comprises at least two modelling levels, on which the system is represented with different degrees of abstraction, and the analysis method comprises the following steps: creating a first part model of the system on a first modelling level by defining objects and links between these objects; creating a second part model of the system on a second modelling level by defining of objects and links between these objects; creating associations or relations between objects of the first and the second modelling level; creating at least one first event chain which represents an action sequence in the first modelling level and describes the action sequence by way of the objects of the first modelling level; creating at least one second event chain which represents the same action sequence in the second modelling level and describes the action sequence by way of the objects of the second modelling level; as well as at least one of the following two steps: automatically analysing the parts models and associations and event chains set up according to the preceding steps, for determining and issuing quality information on the model itself, automatically analysing the part models and associations and event chains created according to the preceding steps, for obtaining information on the modelled system and for issuing this information.
