Research on fault factors of engineering simulators based on quotient space theory

Engineering simulators are important testing equipment that runs through various stages of aircraft system development. In order to improve the efficiency of aircraft development, ensure the production safety of engineering simulators, reduce operating costs, and better apply them to aircraft systems, this article analyzes the four main sources of faults in engineering simulators: the possibility of human factors, equipment factors, environmental factors, and management factors; Combining the quotient space theory, construct an quotient space model for the uncertainty of engineering simulator failures; Then calculate the similarity matrix, quantitatively analyze the similarity between each element, and establish a hierarchical structure of the factors that may cause faults in the engineering simulator. Research has shown that quantitative analysis of the possibility of faults in engineering simulators can effectively optimize management measures and methods, and improve the management level of engineering simulators.
