Abstract
The invention relates to a method for comparing computer-based and data-processing models of a complex system, with a first model and a second model of the system, whereby the models reflect a model of a system behavior by means of predefined objects which represent activities and units within the system. The inventive method comprises the steps of comparing the models and destination of corresponding respective predefined objects of the first and second model, detecting differences in attributes of corresponding predefined objects and outputting the differences to a user. The use of predefined objects—that is, of objects that pertain to a known set of types—enables a more-efficient comparison of models than in unstructured models.

22. A method for modeling a change in a complex system using comparison of at least two computer-based, data-processing models of the complex system, and the method comprising the following steps:
-
by a computer, comparing a first and a second model and determining predefined objects of the first and the second model, wherein the predefined objects are associated with one another in the first and the second model, wherein the first model and the second model of the complex system are present and in each case model a system behavior by way of predefined objects that represent activities and units within the complex system, wherein the first model is a separate and distinct representation of the complex system in a first condition, and wherein the second model is a separate and distinct representation of the complex system in a second condition; by a computer, determining the associations and differences in attributes of the predefined objects associated with one another in the first and second model; and by a computer, using a comparison algorithm to automatically determine action steps required for conveying the complex system from the first condition as represented by the first model into the second condition as represented by the second model. - View Dependent Claims (23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35)
