Equipment reliability evaluation and maintenance method

The invention discloses an equipment reliability evaluation and maintenance method, which comprises the following steps of: traversing all parts in all subway equipment, replacing the parts of which the reliability is less than the lowest reliability tolerance and which reach a replacement cycle, maintaining the parts which do not reach the replacement cycle, updating and calculating the maintenance reliability of the parts with the reliability greater than or equal to the lowest reliability tolerance, and maintaining the parts with the maintenance reliability less than the lowest reliability tolerance. According to the method, the maintenance blindness of the subway equipment is reduced, insufficient maintenance and excessive maintenance are avoided as much as possible, hidden dangers of the subway equipment can be found in time, and the reliability of the equipment is improved. 一种设备可靠性评价维保方法，遍历所有地铁设备中的所有部件，对可靠度小于最低可靠性容忍度且达到更换周期的部件进行更换作业，对未达到更换周期的部件进行维修作业，对可靠度大于等于最低可靠性容忍度的部件更新计算保养可靠度，对保养可靠度小于最低可靠性容忍度的部件进行保养作
