Collaborative Research: SoD-TEAM: A Feedback-Based Architecture for Highly Reliable Embdedded Software

职务名称：“合作研究：SoD-TEAM：基于反馈的高可靠嵌入式软件体系结构“本项目的重点是开发一个理论和架构框架，将反馈控制作为软件工程的主要原则。该方案为提高关键任务软件的可靠性和降低开发成本提供了科学的基础、工具和架构设计原则。确保可靠系统行为的两种常见方法是：1）确保消除错误的科学基础，工具和架构原则，以及2）确保对此类错误的容忍度的基础，工具和架构原则。虽然第一种解决方案已经足够了，但构建完全无错误的大规模系统一直是一项难以捉摸的工作，正如今天的工程工件（例如，车辆召回、连锁停电等）。因此，需要一种新的方法来设计、开发和认证强大的软件，以解决目前做法所带来的日益增加的成本和安全问题。反馈控制已被证明是一个非常成功的工具，以确保正确的行为的复杂的，不好的建模系统中存在的不确定性。这个项目将反馈控制和稳定性包络的原理应用到软件系统的工程中。

Title: "Collaborative Research: SoD-TEAM: A Feedback-Based Architecture for Highly Reliable Embedded Software"The focus of this project is on developing a theory and architectural framework for incorporating feedback control as a main principle of software engineering. This proposal develops scientific foundations, tools, and architectural design principles to improve the reliability and reduce the development cost of mission-critical software. Two common approaches to ensure reliable system behavior are: 1) Scientific foundations, tools, and architectural principles for ensuring elimination of errors, and 2) foundations, tools, and architectural principles for ensuring tolerance to such errors. While the first solution is sufficient, building completely error-free large-scale systems has been an elusive exercise as evidenced by experiences with today's engineering artifacts (e.g., recalls on vehicles, cascading power blackouts, etc). Consequently, a new approach to robust software design, development and certification is needed that addresses the increasing cost and safety implications of the current practices. Feedback control has proven to be a very successful tool for ensuring correct behavior of complex, poorly modeled systems in the presence of uncertainty. This project applies principles of feedback control and stability envelopes to the engineering of software systems.
