Theresearch Of Model And Methods Of House Of Maintenance Of Requirement-oriented Maintenance

As the pace of world economy-integration is accelerating and the situation of global competition is forming,gradually enterprises are faced with a more and more competitive environment.As large-scale production is common increasingly, requirements of products is stringent increasingly on the market. The speed and cost and quality of products of enterprise is the three most critical elements in this competitive environment. Equipment and product maintenance are also the key constraint actors of these three elements. Under this new circumstance it is evident that the relatively lagging of maintenance theory and practice had become a problem. Requirement-Oriented Maintenance is proposed based on this environment, which is a modern maintenance management theories, based on maintenance requirements as the core, based on effectiveness,efficiency,safe and reliable as the goal, based on enterprise integrated information environment, completing the business activities of the Maintenance in the method of maintenance functions to configure MFD, with a view to maintaining the overall best as a benchmark in the maintenance of resource constraints limited conditions, using of various preventive maintenance techniques and methods in an integrated manner , based on enterprise integrated information environment. House of Maintenance is its core technical methods. This paper researched the model of HOM and made a decision with an example.First, the article describes the elements and their definitions of HOM and estates a model of the planning target. Second, the paper quoted the ten steps of house of quality in the QFD and extended it to HOM, but also analyzed the ten steps and introduced the current major solutions and their insufficient, finally, gave more appropriate solutions in each step .Finally, this paper determined the maintenance requirements with incomplete rough centralized decision-making system, determined the basic of importance maintenance needs with an integrated method of the probability of the weight coefficient, determined an important degree of correction factor of the maintenance needs with correction factor of the Kano's model, determined their engineering properties with rough set method ,finally, established the target planning of HOM of the steel mill and made a decision.The new the theory of industrial maintenance will make a better development by the research of ROM. While ROM is QFD, the theory of industrial maintenance will be further extended.
