Description

Technical Field

[0001] The present invention relates to the field of modeling and simulation, and more particularly to a method for constructing a modeling and simulation system architecture capable of simulating on-demand migration execution. Background Art

[0002] Current modeling and simulation software, such as Simulink, SimulationX, Ansys, and AnyLogic, is mostly stand-alone software that typically runs only locally and requires a graphical user interface (GUI) to conduct modeling and simulation activities. Some software offers separate cluster versions that can be installed on high-performance computing clusters, allowing models or projects created with the stand-alone version to be run manually via the command line. Other software also offers VC++ or JAVA code generation (some of which can run in embedded environments), making it easy for users to copy and run the code in other environments.

[0003] With the further application of simulation technology, it is necessary to support simulation anytime and anywhere on different simulation infrastructures. The current modeling and simulation software system architecture, which mainly relies on stand-alone versions and independently deployed cluster versions, has weak interoperability support for on-demand simulation activities on different simulation infrastructures, making it difficult to meet the following modeling and simulation business needs:

[0004] (1) As the scope of simulation development expands from traditional local area networks to the existing global Internet (such as model-based system engineering), it is difficult for users to achieve efficient collaboration of simulations across different enterprises using existing modeling and simulation software.

[0005] (2) As the deployment locations of simulations expand from traditional desktop terminals to existing ubiquitous terminals (such as digital twins), it is difficult for users to achieve seamless migration of simulations to different locations using existing modeling and simulation software.

[0006] (3) As the operation mode of simulation expands from traditional offline small-scale verification to existing online large-scale parallel experiments (such as parallel learning of artificial intelligence, etc.), it is difficult for users to freely switch between simulations of different scales using existing modeling and simulation software. Summary of the Invention

[0007] The purpose of the present invention is to provide a method for constructing a modeling and simulation system architecture for on-demand migration execution of simulations, and to establish an open modeling and simulation system architecture that natively supports on-demand migration execution of simulation systems for simulations to be performed anytime and anywhere on different simulation infrastructures, so as to reduce a large amount of work that requires manual modification, packaging, and deployment of simulation systems.
