Proposal Number: 0820060Title: SASSY: Self-Architecting Software SystemsPI: Daniel MenasceCo-PIs: Hassan Gomaa, Joao Sousa, Sam MalekThis research proposes a framework for Self-Architecting Software Systems (SASSY), a significant paradigm shift in architecting large-scale real-world software systems. Focusing on service-oriented architectures, SASSY includes: 1) Self-architecting: given the service and Quality of Service (QoS) requirements, an optimal architecture is automatically generated with the aid of design patterns. The merit of architectural alternatives is evaluated with the aid of multivariate utility functions. 2) Activity-based specification: behavioral requirements are expressed as activity schemas annotated with QoS requirements and domain ontology. 3) Unification of evolution and adaptation: both the evolution of requirements and changes on monitored run-time conditions and QoS trigger the revaluation of architectural alternatives, and, to the extent possible, the automatic reconfiguration of systems. The intellectual merit lies in the development of a novel framework that advances the representation of software architecture and mixed-initiative activities, while integrating optimization theory and analytic models of QoS. The broader impact includes 1) improved productivity in the software industry, due to significant automation; 2) the open-source availability of the tools developed to support and validate this research; and 3) improved software engineering education by incorporating results of this research into graduate and undergraduate courses at George Mason University and publication at educational forums.

提案编号：0820060标题：SASSY：自架构软件系统PI：丹尼尔Menasce合作PI：哈桑Gomaa，Joao Sousa，Sam Malek这项研究提出了一个自架构软件系统（SASSY）的框架，这是架构大规模真实世界软件系统的一个重要范式转变。 SASSY专注于面向服务的体系结构，包括：1）自架构：给定服务和服务质量（QoS）要求，在设计模式的帮助下自动生成最佳体系结构。建筑方案的优点进行评估与援助的多元效用函数。 2)基于活动的规范：行为需求表示为活动模式，并标注了QoS需求和领域本体。 3)进化和适应的统一：需求的进化和对监控运行时条件和QoS的变化都触发了对架构替代方案的重新评估，并在可能的范围内自动重新配置系统。智力的优点在于开发一种新的框架，该框架提高了软件体系结构和混合主动活动的表示，同时集成了QoS的优化理论和分析模型。 更广泛的影响包括：1）由于显著的自动化，提高了软件行业的生产力; 2）开发用于支持和验证本研究的工具的开源可用性; 3）通过将本研究的结果纳入乔治梅森大学的研究生和本科生课程并在教育论坛上发表，改善了软件工程教育。
