摘要
现实系统一般都具有时序相关特性,传统的数据流分析方法缺乏描述这种特性的能力.本文介绍用于系统分析和系统设计的时序模型方法.系统模型由进程网络组成,不同进程之间通过流式通讯互相关联.进程是按顺序、选择和重复机制组成的事件序列.这样的系统模型结构清晰,易扩充,易修改,并且具有实现的灵活性和有效性.
As data flow analysis is deficient in describing the dynamic behaviour for systems of the real world, this paper introduces a method of modelling system analysis and system design, by which a temporal model consists of a distributed network of processes that communicate through data streams. A model in this approach could be executable directly to check the consistency. It is easily understood, extended and subject to flexible implementations on different environments.
