Multi-level modularization model system architecture method and assembly system and method

The invention discloses a multi-level modularization model system architecture method and an assembly system and method.The architecture method comprises the steps that model basic data, model performance parameters, model scenario parameters and model interaction messages of model components are defined and stored, a multi-level simulation model architecture is constructed, and a basic model component database is obtained; and assembling the model components in the basic model component database through the modularized simulation model assembly combination to obtain a simulation application model, and storing the simulation application model in a simulation application model database. The multi-level model system architecture provided by the invention breaks through the mapping of the models among different levels, so that a user can endow the models with different forms and simulation granularities according to the focus points of the models in different simulation application scenes, the model confidence c
