Abstract: In current software systems，as the existing modeling system is only a single development system，the product of development tends to yield low productivity，low quality when the existing methods are used for feature modeling.The method of generating a feature model from business process model is presented by making use of increasing reusability of software product line.The method by making use of the algorithm of folding operation organizes a use-case group that has the highly related and similar functionality，explicitly shows commonality and variability in business processes，achieves software of the whole business processes，and improves the product of productivity and quality.

摘要： 目前的软件产品系统中，由于现有的造型系统研究的只是单一系统的开发，因此使用现有的方法进行特征造型时就会导致最终开发出来的产品的质量和产量比较低。通过使用增加产品复用性的软件产品线，提出了从业务流程模型中生成特征模型的方法。该方法通过使用重叠操作算法，将业务流程中相似的功能编成一个用例组，清晰地显示了业务流程中的共性和差异性，从而为整个业务流程实现了软件化，提高了产品的质量和产量。
