Abstract

The development of the basic theory of safety science is relatively short compared with other disciplines, and the corresponding basic theory is weaker. However, with the development of science and technology, more and more complex systems have emerged. These systems are significantly different from earlier systems, including in complexity, factor changes, data information, and system control. Traditional reliability and fault analysis methods are difficult to solve. In order to manage these problems, the author proposes a space fault tree theory to study system reliability and system fault evolution process. At present, the space fault tree theory is divided into four parts, the space fault tree theory foundation, the intelligent space fault tree, the space fault network, the system motion space and the system mapping theory. The space fault tree is combined with factor space, a cloud model, fuzzy structure element, and system stability and information ecology methodology. The objective is for the space fault tree theory to complete the system reliability and fault analysis, as well as fault big data analysis, fault logic relationship reasoning, system fault evolution process research and system motion change measurement capability. In order to demonstrate the results of the space fault tree research, this paper is written to briefly introduce the four major parts and main contents and results of the space fault tree theory.

Highlights

  • According to Evolutionary Systems Theory, the emergence of existential risks signifies an evolutionary crisis of complex systems

  • In order to solve the problems of description, analysis and intervention of SFEP, a space fault network is proposed based on the previous research as the third stage of the development of space fault tree theory

  • If a system reliability or safety change is abstracted as a system motion, how can we study the motion of the system? Here, the movement of the system refers to the changes in the systems form, behavior, structure, performance and so on, when the system is stimulated

Summary

Introduction

According to Evolutionary Systems Theory, the emergence of existential risks signifies an evolutionary crisis of complex systems. In the 1950s, developed countries vigorously developed weapons equipment and aerospace fields in a special international environment These fields involved almost all disciplines at that time, consumed immense manpower, financial and material resources, and as a result, became extremely important man-made systems, which were significantly more complex and costly than previous systems. With the development of big data technology, intelligent science, systems science and related mathematical theories, current and future safety sciences, especially the reliability and fault analysis methods of safety system engineering must at least meet the ability requirements of fault handling by big data, reliability causality, reliability stability, reliability reverse engineering, and reliability change process description, etc. The space of system motion and the theory of system mapping are proposed to describe the system motion and structure These are the results of combining system reliability and fault research methods in safety science with intelligence and big data science.
