P0725340SoD: Design of Service-based Software Systems with QoS Monitoring and AdaptationStephen S. Yau (Principal Investigator)Hessam S. Sarjoughian (Co-Principal Investigator)Nong Ye (Co-Principal Investigator)Service-Oriented Architecture (SOA) enables the rapid composition of distributed applications and integration of the "system of systems", and hence is quickly adopted in distributed computing systems. Due to lack of comprehensive understanding of tradeoffs among multiple QoS features associated with service operations in service-based systems (SBS), existing software engineering techniques cannot effectively support the design of SBS satisfying multiple QoS features simultaneously.The objective of this research is to develop a framework effectively incorporating QoS Monitoring and Adaptation (M/A) capabilities in SBS to handle tradeoffs among four important QoS features (timeliness, throughput, accuracy and security) in the design of SBS. To achieve this objective, research on the design of M/A capabilities in Adaptable SBS(ASBS) and simulation-based validation of ASBS design will be conducted.Expected research results include new scientific knowledge about the cause-effect dynamics of activity-state-event-QoS tradeoffs, innovative design support for M/A capabilities, and new simulation principles and methods to support model configurability and scalable simulation of ASBS designs.These results will not only strengthen the scientific rigor of software design and reduce the gap between software design and system design, but also improve the education in software engineering, advanced information systems, and software modeling and simulation.

P0725340 SoD：具有QoS监控和自适应功能的基于服务的软件系统设计Stephen S.尤曾 （主要研究者）Hessam S.萨尔朱吉安 （共同主要研究者）Nong Ye 面向服务的体系结构（Service-Oriented Architecture，SOA）使分布式应用程序的快速组合和“系统的系统”的集成成为可能，因此很快被分布式计算系统所采用。由于缺乏对基于服务的系统（SBS）中与服务操作相关联的多个QoS特征之间的权衡的全面理解，现有的软件工程技术不能有效地支持同时满足多个QoS特性的SBS的设计，本研究的目的是开发一个有效地结合QoS监控和自适应（M/A）的框架在SBS的设计中，SBS中处理四个重要QoS特征（及时性、吞吐量、准确性和安全性）之间的权衡的能力。为了实现这一目标，将开展自适应SBS（ASBS）中M/A能力设计和基于仿真的ASBS设计验证研究，预期研究成果包括关于活动-状态-事件-QoS权衡的因果动力学的新科学知识，对M/A能力的创新设计支持，提出了新的仿真原理和方法，支持ASBS设计的模型可配置性和可扩展性仿真，这些结果不仅将增强软件设计的科学性和严谨性，并缩小软件设计与系统设计之间的差距，同时也改善了软件工程、先进信息系统以及软件建模与仿真的教育。
