构件式建模方法在系统建模中的应用研究

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。

Study on component-based method of system-level modeling

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 WLANwireless 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.
