基于UML的软件复用开发性能评估模型的推导
Derivation of UML Based Performance Models for Design Assessment in a Reuse Based Software Development Approach
摘要：
基于重用的软件开发为提高软件产品的质量和生产力提供了机会。软件系统质量的一个最关键的方面是它的性能。在整个开发过程中系统地应用软件性能工程技术，可以帮助确定设计替代方案，保留所需的质量，如可扩展性和可重用性，同时满足性能目标。在目前的情况下，大多数性能失败是由于在开发过程的早期，特别是在设计阶段，缺乏对性能问题的考虑。这些性能故障会导致客户关系受损、用户生产力损失、调整或重新设计导致的成本超支以及错过市场窗口。在本文中，我们提出了基于UML的性能模型的设计评估在一个基于重用的软件开发方案。
英文摘要：
Reuse-based software development provides an opportunity for better quality and increased productivity in the software products. One of the most critical aspects of the quality of a software system is its performance. The systematic application of software performance engineering techniques throughout the development process can help to identify design alternatives that preserve desirable qualities such as extensibility and reusability while meeting performance objectives. In the present scenario, most of the performance failures are due to a lack of consideration of performance issues early in the development process, especially in the design phase. These performance failures results in damaged customer relations, lost productivity for users, cost overruns due to tuning or redesign, and missed market windows. In this paper, we propose UML based Performance Models for design assessment in a reuse based software development scenario.
