BRM-A Behavior Based Requirements Modeling Method

摘要

Software behaviors have long been recognized to be essential components involved in requirements modelling process by many researchers both from academia and industry. In this paper, we propose a divide and conquer modeling method - Behavior based Requirements Modeling method (BRM), to modeling behaviors of software system. The target system is decomposed into sub-domains, ViewPoints(VPs), and scenarios at successive levels. Requirements modeling could be carried out in different VPs respectively. Behaviors of the target system are identified within each scenario. A formal description language - Behavior Description Language (BDL) is proposed to describe these behaviors, as well as the model of the target system.
