基于TMSC的需求建模方法研究

Research on requirement modeling method based on TMSC

本文针对消息序列图(MSC)在进行需求建模时只能用来描述确定的行为的不足,分析了用采用带有触发机制的消息序列图(TMSC)所具备的特点及如何弥补MSC的不足。通过实例,本文分别介绍了TMSC在条件场景下自底向上建模方法和不完全场景下迭代建模方法以及他们能解决的建模问题。通过实例说明了TMSC方法在需求建模时,描述条件场景和不完全场景中优势,可以去除MSC建模中的不合理性情况,提高建模效率。

This paper analyses some deficient in Requirement Modeling Method when using Message Sequence Chart(MSC),and then analyses how the Triggered Message Sequence Chart(TMSC) can make up some deficient of the MSC.We give two instance about Requirement Modeling using TMSC.One of the instances is Bottom-up Modling method on conditions scene,the other is the Iterative Modeling method on incomplete scene.It shows that TMSC can outperform the MSC method as it reduces some unreasonable effect of MSC.
