摘要
需求工程的复杂性和不确定性,要求需求模型具有一定的灵活性和适应动态变化的能力,面对需求的不确定性,为了资源共享,完善需求工程,提出一种处理动态需求的演化方法,根据新需求特征,重用需求模型库中的存放模型,演化生成新的需求模型,增强了所求模型的重用性和适应性;并且给出了形式化描述和演化算法;最后用一个例子说明实现过程。
Because of the complexity and uncertainty of the requirements engineering, the flexibility and the ability of supporting dynamic changes are the basic requirements of a requirements model. An evolution method for handling dynamic requirements is proposed, it reuses requirements model in requirements model database according to new requirement features and generates optimization requirement model, which enhance reusability and adaptability of the requirements model. Then formalization description and evolution algorithm are presented in this paper,. At last, an example is presented to demonstrate the evolution method.
