Research And Implementation Of Composable Modeling Method Based On BOM

As the system simulation techonology has developed for about more than half a century, it has become one of the major methods to solve practical problems through using system engineering theories and methods. With the continuous extension of simulation application areas, the objects to model and simulate, as simple systems in early times, for nowadays have transformed to complicated giant engineering systems, military operations, equipment systems and so on. Higher requirments need to satisfy the extensile, adaptable, reusable and interoperational modeling. Thus, the exploiture of simulation models is urgently expected to form the final system models fleetly which satisfy different requirments through assembling child components neatly, so that the validity of modeling could be retained in the combination, activaty and process of real structure.According to the actuality concerned, this article present a composable modeling method based on BOM rules, studied and designed the structure of coupled models based on BOM rules, figured out several key techniques in the process of assembling models, designed a composable modeling antetype using the composable modeling method, and established a application instant to test at last.First of all, after analysing the advantages and disadvantages of the traditional composable modeling methods, this article present a composable modeling method based on BOM rules. The composable modeling method includes two parts, syntactically composable and semantically composable. It described the interface constraints, mapping relation and so on. It also discusses and analyses the composable validity simply.Secondly, after analysing the advantages and disadvantages of the basic model structure of the FLAMS and JWARS system, this article designed the structure of coupled models based on BOM rules. The article also designed the description information structure of the atomic model coupled model, analysed the function of the composable modeling manager, and designed the frame structure and software structure of the composable modeling manager.Then the article studied and figured out several key techniques in the process of assembling models. The first is the assembling mechanism of models and realization, which is about the relation of atomic models in coupled models. The second is management and control to atomic models, which is about the whole lifecycle of atomic models. The third is the filteration, distribution and storage of data in coupled models, which influence the efficiency of coupled models.At last, the article designed and realized a composable modeling frame antetype. Composable modeling method, the structure of coupled models and the key techniques in the process of assembling models support the composable modeling frame antetype with theories and techniques. The article also took an application instant as an example, modeled it through the composable modeling method, and tested the efficiency of the coupled model.
