Aggregation and Deaggregation Methods for Link and Transit Relationship Models

Abstract

An aggregation and de-aggregation method of link and transfer relationship models is provided, and aggregation and de-aggregation are a pair of reciprocal processes. The present invention compresses a plurality of related links into a new link by performing composite mapping on the relevant links in the basic model, and realizes model aggregation; referring to the internal structure of the original system, a link is disassembled by performing reverse composite mapping on a link. It is divided into multiple related links to realize the disaggregation of the model. This method realizes the aggregation and disaggregation of the model through the compound operation of the mapping, so that the link and transfer relationship models meet the different resolution requirements of the simulation, which helps to improve the efficiency and adaptability of the simulation modeling.

Description

Aggregation and Deaggregation Methods for Link and Transit Relationship Models technical field The invention belongs to the field of simulation modeling, and relates to a model aggregation and de-aggregation method, in particular to an aggregation and de-aggregation method for link and transfer relationship models. Background technique The link and transfer relationship modeling method can provide a basic model for the hardware-in-the-loop simulation design of complex equipment (see another patent application filed by the applicant on the same day, entitled: "Link and transfer relationship modeling method"). The links and transfer relationship models established by this method include: 1. Functional domain All independent functions by the system f i A finite set F of functions constituting the whole system: F={f 1 , f 2 ,...,f n}, where f i Indicates each independent function in the system function set, f i ∈F. 2. Links corresponding to independent functions ...

AI Technical Summary

Problems solved by technology

The accuracy of the simulation puts forward requirements on the resolution of the model. The aggregation and de-aggregation methods of the model are directly related to the resolution index of the model. Under certain attributes, the model is simplified after aggregation, and the simulation design is simplified. The resolution of simulation modeling decreases; under certain attributes, after disaggregation, the resolution of simulation modeling increases, but the model becomes more complex and the workload of simulation design increases
