Automating software model evolution

软件演进是一个涵盖软件产品整个生命周期的变化过程。在所有的软件过程中，进化是最昂贵的。模型在记录软件架构并使其易于理解方面是至关重要的。一个复杂的软件系统会随着时间的推移而发展，它的架构会随着系统面对环境的挑战而改变。因此，模型和元模型在软件演化中起着关键的作用。实证研究表明，要完全预测软件的变化是非常困难的。维护（更改）软件系统所花费的时间和金钱比最初的开发要多。根据欧洲信息学和数学研究联盟（ERCIM）软件发展工作组的说法，“克服或避免软件老化的负面影响的唯一方法是将变更置于软件开发过程的中心。”因此，有必要为软件演进提供更好、更自动化的支持

Software evolution is a change process that covers all the life cycle of a software product. Of all the software processes, evolution is the most expensive. Models are critical in documenting software architectures, and making them easy to understand. A complex software system evolves over time and its architecture will change as the system meets the challenges of its environment. Therefore, models and meta-models play a key role in software evolution. Empirical research shows that it is very difficult to completely predict software changes. More time and money are spent maintaining (changing) a software system than on its original development. According to the European Research Consortium for Informatics and Mathematics (ERCIM) working group on software evolution "The only way to overcome or avoid the negative effects of software aging is by placing change in the center of the software development process." There is therefore a need to provide better and more automated support for software evolution
