    • A method for modeling requirements of a product includes defining an abstract use case for each feature of said product, hierarchically decomposing each abstract use case until concrete use cases are specified for each feature, depicting every actor who would use the product as communicating with a concrete use case through a boundary, and programmatically extracting requirements from the use case diagram. Programmatically extracting requirements further includes converting use case diagrams into directed acyclic graphs, where each use case corresponds to a node of a graph and each relationship between a pair of use cases is represented by a directed edge between the corresponding pair of nodes in the graph where a directed edge points from a parent node to a child node, converting the directed acyclic graph into a tree, and searching the tree to extract the requirements.
    • 用于对产品的要求进行建模的方法包括为所述产品的每个特征定义抽象使用情况,分级地分解每个抽象用例,直到为每个特征指定具体用例,描绘将使用该产品与具体的通信的每个演员 用例,并以编程方式从用例图中提取需求。 编程提取要求还包括将用例图转换为有向无环图,其中每个用例对应于图的一个节点,一对用例之间的每个关系由图中相应的一对节点之间的有向边表示, 从父节点到子节点的有向边缘点,将有向无环图转换成树,并搜索树以提取要求。
