Comprehensive evaluation of signal equipment status based on fuzzy synthetic evaluation

The signal system is the key content of rail transits, and its equipment status evaluation helps to find the hazards of the system in time and ensure the function of the system. In this paper, a comprehensive evaluation indicator system and evaluation model of signal equipment state are established, and a signal equipment state evaluation method based on fuzzy synthetic evaluation is proposed. The applicability of the method is verified by combining with the case analysis. It is expected to provide reference for the ideas and methods in the whole life cycle management process of rail transits.
