| 摘 要： | 现有系统可靠性分析方法一般具有针对性，缺乏广泛的适应性和扩展性。由于智能科学、信息科学和大数据技术的涌现和发展，使得传统可靠性分析技术难以适应新的需要。因此作者提出了空间故障树理论，目的是分析多因素影响下的系统可靠性变化特征。将空间故障树理论与因素空间理论、云模型、模糊数学及系统稳定性等相结合，使其具有智能分析和故障大数据处理能力，以满足未来技术环境下的分析要求。本文论述了空间故障树和因素空间的发展史及主要理论与功能；以及两种理论结合，描述和分析系统演化过程的可行性。研究表明，空间故障树理论具有良好的扩展性和适应性，可适应未来技术环境，也可作为系统演化过程分析的普适框架。

| Abstract: | The existing system reliability analysis methods are generally targeted and lack extensive adaptability and expansibility. Moreover, due to the emergence and development of intelligent science, information science, and big data technology, the traditional reliability analysis technology can hardly meet the new demands. Therefore, the authors propose the space fault tree theory to analyze the reliability change characteristics of systems influenced by multiple factors. The space fault tree theory is combined with factor space theory, cloud model, fuzzy mathematics, and system stability theory to enable it have the ability of intelligent analysis and fault big data processing, so as to meet the analysis requirements in the future technology environment. This paper discusses the development history and the main theories and functions of the space fault tree and factor space, as well as the feasibility of combining these two theories to describe and analyze the system evolution process. The results show that the space fault tree theory has good expansibility and adaptability; it adapts to future technology environment and can also be used as a universal framework for the analysis of a system evolution process. |
