| After systematical analysis of the maintenance-repair status of construction machinery in our country, this paper summarizes the problems of maintenance-repair, and discusses the countermeasures against them, basing on the research condition of maintenance and repair both at home and abroad. In the meantime, this paper presents some propositional countermeasures to both construction machinery maintenance-repair enterprises and construction enterprises, and introduces the maintenance-repair managing engineering and the mode of Reliability Centered Maintenance into the construction machinery maintenance-repair, and ulteriorly presents the new concepts about the service of Reliability Centered Maintenance. To seek the way which promoting construction machinery Reliability Centered Maintenance service level, this paper discusses the factors of affecting the level, and undertakes to evaluate the level by applying fuzzy mathematics theories. Meanwhile, a evaluation software was programmed to accomplish the evaluation.
