中文摘要： 随着信息化时代的到来，一大批以信息化技术为核心的新一代复杂系统广泛应用于国防和国民经济各领域。这些复杂系统通常能伴随着环境或功能单元的状态变化进行实时重构。实时重构的出现，使得系统运行过程中功能单元的逻辑关系也会产生时变，以往面向功能单元静态逻辑关系的系统可靠性研究方法无法解决当前具有重构特征系统的可靠性问题。如何设计分析、评估改进具有重构特征系统的可靠性，避免系统重构过程中发生崩溃问题的发生已经成为当前复杂系统建设中迫切需要解决的重大现实问题。本项申请以新一代装备信息化建设的工程需求为背景，分析建立具有重构特征系统可靠性模型框架，探索研究系统重构的机理与运行规律，分析提出描述系统重构功能的定量模型与建模方法以及考虑重构特征的系统可靠性模型与建模方法，分析并揭示系统重构对系统可靠性影响的基本规律，为具有重构特征系统的可靠性设计、分析与改进提供理论与技术支撑。

英文摘要： With the new era of information, a large number of advanced complex systems are widely used in various fields of national defense and national economy. These complex systems can reconfigurate with the changing states of their operation environment and function units. Obviously, with the advent of system reconfiguration, the logical relationship of function units during the running process are time-varying. The reliability domain problem of reconfiguration characterized systems cannot be solved by just using the classic function unit oriented static system reliability methods. Thus, it becomes imminent to work out the methodology of designing, analyzing, assessing and improving the reliability of the advanced systems with the characteristics of reconfiguration, which will help us to resolve the important practical problems in system engineering, and to avoid crash accidents from happening during the reconfiguration process. Therefore based on the requirement of the informationization construction, system reliability model framework with the characteristics of reconfiguration will be analyzed and constructed, the system reconfiguration mechanism and operation law will be studied in this project, then the quantitative model for describing the system reconfiguration function and the system reliability model of these types of systems will be presented, which illustrate the principle of how system reconfiguration affect system reliability. This project will help establish strong theoretical base and provide technical support for the reliability design, analysis and improvement of reconfiguration characterized systems.
