Application of Metamodel for Airborne Complex Crosslinked Systems

With the development of science and technology, functional crosslinking and resource sharing have become the common characteristics of large complex systems. At the same time, it also brings the challenges of fault diagnosis and location, such as the enhancement of system fault correlation, implicit spread and chaos. As a result, the traditional model is not sufficient to describe the functional failure mode of complex crosslinking systems. In this paper, a metamodel-based complex crosslinking system modeling method is proposed and applied to build the model for airborne complex crosslinking system. The influencing factors and relationships between system functions and faults are studied, and a metamodel-based fault example of airborne complex crosslinking system is realized.The application of metamodel technology to the establishment of airborne complex crosslinking system model can make the subsystem model achieve a higher level of abstraction. The good general performance of metamodel solves the problem of complex system model reuse, provides quantitative support for subsequent development, and simplifies the correlation characteristics of airborne complex system crosslinking function. It provides the foundation of domain model for simulation, design and development of subsequent systems.
