Patent ID: 8661419

Claim:
A computer apparatus comprising: a first processor; a digital storage medium adapted to store data comprising a simulation analysis model executable by the first processor of the computer apparatus, the simulation analysis model of the data comprising: a first data object; a second data object forming an outer interface of the simulation analysis model; a third data object comprising contents of the simulation analysis model as further processable data; and a fourth data object comprising the simulation analysis model of the third data object as prepared executable simulation; wherein the simulation analysis model forms a hierarchical part of a superordinate simulation analysis model; and wherein the first processor of the computer apparatus operate operates according to the data stored in the digital storage medium such that the first data object controls access to the further processable data of the third data object and to the prepared executable simulation of the fourth data object, and such that the first data object controls access to the further data objects based on predetermined access authorization information.
