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

Abstract

The invention relates to a semantic mapping-based combination simulation method and device, equipment and a medium, and the method comprises the steps: obtaining a combination simulation task, wherein the combination simulation task comprises a plurality of simulation events, and each simulation event is formed by connecting a plurality of simulation parts; converting the simulation parts into atomic models by defining internal execution logic and external interface logic of the simulation parts, and converting the combination simulation task into a semantic layer combination simulation model; according to the combination simulation task, obtaining a pre-stored grammar layer combination simulation model; and according to the semantic layer combination simulation model and the grammar layer combination simulation model, obtaining a mapping relation of conversion from the semantic layer to the grammar layer, establishing an executable layer combination simulation model corresponding to each simulation event, and inputting the executable layer combination simulation models into a simulation system for combination simulation. By adopting the method, the relation between simulation system construction and simulation context constraint can be established, the modeling process is simple and rapid, and modeling results are convenient to combine.

Description

technical field [0001] The present application relates to the technical field of system modeling and simulation, in particular to a combined simulation method, device, device and medium based on semantic mapping. Background technique [0002] Modeling and Simulation (M&S) is an emerging discipline. Modeling is the abstraction of real data, processes, constraints, etc. into various models, while simulation is the execution of models. After years of development, combined simulation has become a research hotspot in the field of modeling and simulation. [0003] In the combined simulation method, it mainly includes: the method based on the Common Library Approach (CLA), the method based on the Product Line (PL), the method based on the Model Driven Architecture (MDA), and Methods based on the Interoperability Protocol Approach (IPA), etc. [0004] Although there have been many studies on the combination of simulation components and some progress has been made, there are still ...

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
