An increasingly important requirement for software based systems is the ability to deliver reliable, correct, and safe services in a timely manner. This kind of ability is usually called system dependability which is demonstrated through features like self-managing, self-maintaining, and self-repairing/self-healing. These features are becoming a requirement of software based systems in many industrial sectors, e.g., in some manufacturing environments (such as steel mills and chemical plants) and critical infrastructures/facilities (such as power grids and nuclear power plants) where system failures or unexpected shutdowns will cause significant economic losses or even destroy entire plants/facilities. The objective of this research is to develop scientific and engineering foundations, innovative technologies, and practical solutions to support distributed, automated, dependable computer systems that are able to handle faults and uncertain changes at real time without (or with reduced) degrading of services. The emphasis will be on understanding, modeling, designing, and implementing complex software systems in dynamic manufacturing environments and critical infrastructures/facilities. We will particularly investigate the application of intelligent software agents in this area, by integrating with other concepts, principles, and technologies, including active event-based concepts, optimal control theory, scheduling and optimization, data mining, and distributed sensor networks.

对基于软件的系统的一个日益重要的要求是能够及时提供可靠、正确和安全的服务。这种能力通常被称为系统可靠性，它通过自我管理、自我维护和自我修复/自我修复等功能来展示。这些功能正在成为许多工业部门中基于软件的系统的要求，例如，在一些制造环境(如钢厂和化工厂)和关键基础设施/设施(如电网和核电站)中，系统故障或意外关闭将导致重大经济损失，甚至摧毁整个工厂/设施。这项研究的目标是开发科学和工程基础、创新技术和实用解决方案，以支持能够实时处理故障和不确定变化而不会(或减少)服务降级的分布式、自动化、可靠的计算机系统。重点将放在理解、建模、设计和实施动态制造环境和关键基础设施/设施中的复杂软件系统上。我们将结合其他概念、原理和技术，特别研究智能软件代理在这一领域的应用，包括基于主动事件的概念、最优控制理论、调度与优化、数据挖掘和分布式传感器网络。
