Abstract

A digital twin management system manages a virtual model that represents an actual physical system in a virtual space on a real-time basis. To generate an integrated virtual model by adding a second virtual model to a first virtual model, a processor of the digital twin system extracts multiple parts that can be used in common in the first virtual model and the second virtual model, generates multiple integrated virtual models that are candidates of an integrated virtual model by changing the extracted parts that can be used in common, calculates an evaluation of each of the generated integrated virtual models, and outputs configuration information regarding each of the integrated virtual model candidates and an evaluation of the integrated virtual model candidate in association with each other.

Claims (32)

1. A digital twin management system for managing a digital twin that represents an actual physical system in a virtual space, the digital twin management system comprising:

a processor; and

a memory that stores a predetermined computer program that is executed by the processor, wherein,

to generate an integrated scenario by adding a second scenario to a first scenario, the processor

extracts multiple parts that can be used in common in the first scenario and the second scenario,

generates multiple integrated scenario candidates that are candidates of the integrated scenario, by changing the extracted parts that can be used in common,

calculates an evaluation of each of the generated integrated scenario candidates, and

outputs configuration information regarding each of the integrated scenario candidates and the evaluation of the integrated scenario candidate in association with each other.

2. The digital twin management system according to claim 1 , wherein

each of the first scenario, the second scenario, and the integrated scenario is formed by templating, as a scenario, a digital twin configuration that includes information indicating a configuration of a target actual system, attribute information indicating a purpose of the scenario, data derived from the actual system, a process flow that is executed in reference to the obtained data, an analysis model included in the process flow, and an input/output parameter of the analysis model.

3. The digital twin management system according to claim 2 , wherein,

by comparison of the first scenario with the second scenario, multiple parts that can be used in common by the first scenario and the second scenario are extracted.

4. The digital twin management system according to claim 1 , wherein

configuration information regarding each of the integrated scenario candidates and the evaluation of the integrated scenario candidate are provided to a user through a monitor display.

5. The digital twin management system according to claim 4 , wherein

the evaluation is given in terms of resource consumption and/or performance stability.

6. The digital twin management system according to claim 5 , wherein

past data that has been used in the first scenario is used to calculate the evaluation.

7. The digital twin management system according to claim 6 , wherein

selection from among the integrated scenario candidates is made in accordance with a prepared policy.

8. The digital twin management system according to claim 4 , wherein

the evaluation includes resource consumption, performance stability, and a possible effect on a separated system related to the actual system.

9. The digital twin management system according to claim 8 , wherein,

regarding an integrated scenario candidate selected by a user from among the integrated scenario candidates, information regarding a possible effect on the separate system is provided to the separate system and/or another system.

10. The digital twin management system according to claim 1 , wherein

the actual system is an industrial apparatus that is used in a factory.

11. A digital twin management method that is a virtual model management method for managing a digital twin that represents an actual physical system in a virtual space by using a computer, wherein,

to add a second scenario to a first scenario, the computer

extracts multiple parts that can be used in common in the first scenario and the second scenario,

generates multiple candidates of an integrated scenario by changing the extracted parts that can be used in common,

calculates an evaluation of each of the generated integrated scenario candidates, and

outputs configuration information regarding each of the integrated scenario candidates and the evaluation of the integrated scenario candidate in association with each other.
