0447594Jane huang保罗大学职业：支持系统质量影响分析的以目标为中心的可追溯性软件产品越来越多地部署在安全关键应用中，在这些应用中，系统故障可能导致生命损失、环境破坏或重大经济损失。不幸的是，许多失败的描述将根本原因归结为与非功能性质量（如安全性、安全性或可靠性）的错误实现相关的问题。这项研究的目的是开发一种被称为目标中心跟踪（GCT）的新技术，它将为管理系统质量提供有效的支持。GCT的目的是防止系统范围内的非功能性质量在变更过程中受到不利影响，并确保系统的长期质量。这项工作将涉及使用概率和基于约束的方法开发功能性和非功能性需求之间的动态跟踪技术。将定义启发式方法和支持方法，以确定变化对系统目标的传递性影响，并自动重新评估现有的评估模型，如性能模拟和可执行的场景。将开发一个将GCT与流行的体系结构评估工具连接起来的标准接口。这项工作具有潜在的重大影响，因为它解决了工业中普遍遇到的一个复杂而实际的问题。

0447594Jane HuangDePaul University CAREER: Goal Centric Traceability for Supporting Impact Analysis of Systemic QualitiesSoftware products are increasingly deployed within safety critical applications in which system failure could lead to loss of life, environmental damage, or significant financial loss. Unfortunately numerous accounts of failures cite the root cause as problems related to the incorrect implementation of non-functional qualities such as safety, security, or reliability. The objective of this research is to develop a new technique known as Goal-Centric Traceability (GCT) that will provide effective support for managing systemic qualities. GCT is designed to prevent systemwide non-functional qualities from being adversely impacted during the change process and to ensure the long-term quality of the system. The work will involve developing dynamic traceability techniques between functional and non-functional requirements using probabilistic and constraint-based methods. Heuristics and supporting methods will be defined for identifying the transitive impact of a change upon systemic goals and for automating the re-evaluation of existing assessment models such as performance simulations and executable scenarios. A standard interface for interfacing GCT with popular architectural assessment tools will be developed. The work has potential for significant impact as it addresses a complex yet practical problem commonly experienced in industry.
