Analysis of Reliability for Dehumidification Control System in Underground Engineering Based on Markov Process

This paper introduces application of Markov process in reliability research. Aim at the reliability of complex repairable system and establish mathematical model for dehumidification control system according to Markov model. Deriving formula of complex repairable system is built based on this process. Sum up the solving methods of reliability for dehumidification system and calculate the value of reliability through the project case. Research results will provide references for maintenance and diagnosis of dehumidification control system in underground engineering.
