Combined simulation method, device, equipment and medium based on semantic mapping

Abstract

This application relates to a combined simulation method, device, device and medium based on semantic mapping. The method includes: obtaining a combined simulation task, the combined simulation task includes multiple simulation events, and the simulation event is composed of multiple simulation components connected; Execute logic and external interface logic, convert simulation components into atomic models, and convert combined simulation tasks into semantic layer combined simulation models; obtain pre-stored syntactic level combined simulation models according to combined simulation tasks; combine semantic layer combined simulation models and grammars The layer combination simulation model is obtained to obtain the mapping relationship from the semantic layer to the syntax layer, and the executable layer combination simulation model corresponding to each simulation event is established, and the executable layer combination simulation model is input into the simulation system for combination simulation. The method can establish the connection between the simulation system construction and the simulation context constraints, the modeling process is simple and fast, and the modeling results are conveniently combined.

Description

Technical field [0001] The present application relates to a system modeling and simulation technologies, and particularly to a simulation based on a combination of the semantic mapping method, apparatus, devices and media. Background technique [0002] Modeling and Simulation (M & S) is an emerging discipline, data modeling is the reality of the process, for a variety of restrictions abstract model, and the model simulation is executed. After years of development, the combination of simulation has become a hot topic in the field of modeling and simulation. [0003] In the method of combining simulation, including: based on a common model library (Common Library Approach, CLA) approach, based on the product line (Product Line, PL) approach, based on model-driven architecture (Model DrivenArchitecture, MDA) approach, and based interoperability protocol (interoperability ProtocolApproach, IPA) and the like. [0004] Although there have been many studies on the combination of simulat...

AI Technical Summary

Problems solved by technology

[0005] 1. The strength and depth of research on semantic combination problems are not enough, and the main focus is on the combination of grammar and semantic rules. There has not yet emerged a relatively mature simulation model semantic combination simulation technology system that supports engineering

[0006] 2. In the formal modeling of combined simulation, only focus on the modeling method research of the simulation model, and there are not many studies on the semantic formal description of the simulation model, and the simulation context factors are not considered in the modeling process of simulation components and simulation requirements description, ignoring the inherent relationship between the construction of the simulation system and the constraints of the simulation context

[0008] 4. In terms of analysis of simulation combination properties, it is difficult to judge whether the simulation model supports reuse in the specified simulation context because the simulation context factor is ignored in the modeling process
