Reliability analysis method and system for component echelon utilization building system

The invention relates to a reliability analysis method and system for a component echelon utilization building system, and belongs to the field of fabricated buildings. The method comprises the following steps: determining safety performance indexes of the building system, wherein the safety performance indexes comprise a first failure probability and a first repair probability under a non-repair condition, and a second failure probability and a second repair probability under a fault occurrence condition; respectively determining a first correction coefficient of the first failure probability and a second correction coefficient of the second failure probability based on the echelon utilization times of the building system component parts; determining a health performance variable of the building system based on the health performance indicator of the component of the building system; and determining the reliability of the building system based on the parameters. According to the method, based on the reliabil
