Research On Technology Of Dynamic Loading Of Simulation Model

With the development of the distributed simulation techniques and the complexity of the simulation application requirement in military domain, some problems are exposed in the constructions of simulation application systems, such as poor reuse of simulation models, redundancy of mass resource, difficulty of system deployment, static assignment of resource, scarce capacity of management, etc. This thesis researches on the development and integration of simulation application systems from the technology of dynamic loading of simulation model, reflective components and simulate engine, and a demo system is designed and implemented according to the practical application requirement, the main contents have been listed as bellow: It is proposed in this thesis with a new technology solution, called dynamic loading of simulation model. In this novel method, simulation model components can been deployed into simulation environment during running time, then load and run in the simulation system, and the simulation models have the characteristic of plug and play; The simulation models can communicate under High Level Architecture and been deployed under Grid, and simulation application can be structured in the form of components.The Reflection Component-based Simulation Model is designed in this thesis. This kind of simulation model not only has the ability of self-describing but also can reflect the information to the upper application, then the upper application can genarate and drive simulation object by using the information. Through analyses several main component techolologis, and the structure of Base Object Model, the RCSM takes the policy of .NET and BOM as design guidelines, the interior structure and the external interfaces of which are designed, and the example of which is gived.The Simulate Computing Engine is designed in this thesis, and based on which the all-purpose running environment for simulation models componets is constructed. The Simulate Computing Engine which is the software environment for the simulation models to run is designed from two aspects: the logistic structure and interior structure. And based on the design, the flow and approach for the model to load are gived, the dynamic loading frame and the encapsulation of simulation application are designed, with the additional design of the data exchange and the executive structure for the model componets, Through the above resarch, the unitive environment for simulation models to load, deploy and run is provided.The demo system - RCSM-LoadFrame is implemented at last. In this system, the simulation model can be upgraded independently, deployed dynamically, and managed centrally, and the simulation environment can be configured flexibly, the resources can be monitored globally.
