Selecting optimal reuse scenarios based on the two-stage procedure model in a software product line
两阶段过程模型下的产品线复用策略优化

We investigate the selection of the reuse scenarios on a two-stage software product line for satisfying the given requirements within a budgetary constraint while maximizing the product quality. Based on the two-stage process model, we conclude 6 typical reuse scenarios and their realizations, and propose a method for selecting the best one from them by considering the budget limitations, the development cost and time, the failure rate and reliability to optimize the production quality. Based on the Bayes theory, we developed a simplified testing function for estimating the intensity of domain testing in the developing phase of the product. A mailbox service system is used as a real example to demonstrate the effectiveness of the model.
