Method and Device for Optimizing the Robustness of a Digital Twin

A computer-implemented method for optimizing a robustness of a digital twin of a system comprising a system drive twin, the system drive twin comprising a behavior model which describes an undisrupted behavior and a behavior of the system which is to be expected under influence of at least one predefined disruption, the method comprising:

• providing a model of an environment representing an environment model, the system being configured to interact with the environment such that the environment supplies at least one input signal to the system and receives at least one output signal from the system, and the system together with the environment jointly form an overall system;
• linking the system twin and the environment model to form an overall model comprising a model of the overall system;
• executing the overall model at least twice to obtain simulation data, during a first execution, the overall model being utilized in an undisrupted state and, in cases of a second execution of the overall model, the at least one predefined disruption of the system being co-simulated to simulate a behavior of the overall system under influence of the at least one predefined disruption acting on the system;
• analyzing simulation data to ascertain an expected effect of the at least one disruption on the overall system from a comparison of data ascertained during the first execution of the overall model with data ascertained during the second execution of the overall model;
• and
• communicating the ascertained at least one action to a user depending on the expected effect.

A computer program product for the facility as claimed in claim 13, wherein the computer program product comprises instructions which, when executed by a computing system of the facility, cause the facility to:

• provide a model of an environment representing an environment model, the computing system being configured to interact with the environment such that the environment supplies at least one input signal to the computing system and receives at least one output signal from the computing system, and the computing system together with the environment jointly form an overall system;
• link a system twin and the environment model to form an overall model comprising a model of the overall system;
• execute the overall model at least twice to obtain simulation data, during a first execution, the overall model being utilized in an undisrupted state and, in cases of a second execution of the overall model, the at least one predefined disruption of the computing system being co-simulated to simulate a behavior of the overall system under influence of the at least one predefined disruption acting on the computing system;
• analyze simulation data to ascertain an expected effect of the at least one disruption on the overall system from a comparison of data ascertained during the first execution of the overall model with data ascertained during the second execution of the overall model;
• and
• communicate the ascertained at least one action to a user depending on the expected effect.
