网络式软件作为基于Internet这一开放环境运行的软件的一个典型代表,其全开放运行机制使得需求过程的自动调度尤为重要.为此,首先将网络式软件的需求状态(NRS)划分为6个状态,并利用网络式软件需求状态跟踪(NRST)图刻画出了各个需求状态之间的转化.最后,利用NRST,有效地实现了网络式软件需求过程的自动转换与调度,使得整个需求分析过程能够在Internet网上无须人的过多干预,而由计算机自动完成.
Networked software is a typical example of a kind of software running in the open environment such as Internet.The automatic switch of requirement process is vital because of its entirely open running mechanism.Because of it,requirements status of networked software is divided into six child status based on the introduction of the concept of networked software.The transition among requirement status is described by requirements status tracking of networked software(NRST).At last,requirement process switch of networked software is implemented in this way and then the whole requirements analysis process is realized automatic online.
