摘　　要：为了使系统级建模过程工程化,提高模型构件的重用度,针对建模的实现过程,提出了通用的建模模式和构件式建模方法。将数据抽象、信号原语、异步并发机制处理等过程归纳为建模模式,并建立了典型的软硬件构件模型以便建模时重用,方便了快速建模和模型构件的重用;以无线接入系统为例,运用构件式建模方法建立了其系统模型,仿真分析了WLAN网络环境下站点数等参数对有效吞吐量的影响。实践表明,构件式建模方法能加快系统的建模过程,有助于实现建模过程的工程化。In order to engineer system-level modeling process,improve the reusability of the model components,this paper proposed a general modeling method and component-based modeling approach.Uniformly,data Abstraction,signal primitives,asynchronous concurrent mechanism and other processes of modeling were summarized as modeling patterns.Furthermore,to facilitate the rapid prototyping and improve the reuse of model components,this paper created a typical hardware and software component model.Taking the wireless access system as an example,which was built according to component-based modeling method based on the simulation of the model,the influences of the number of stations on the valid throughput were analyzed in the WLAN（wireless local-area network）.The practice shows that the component-based modeling method can speed up the modeling process and contribute to the achievement of the modeling process engineering.
