Based On Predictive Maintenance Of Equipment Management Information And Decision Support Systems

The managing system of equipment maintenance has gone through two phases: Breakdown Maintenance (BM) and Time-Based Maintenance (TBM). And now the managing system of equipment maintenance is entering into the phases of Predictive Maintenance (PM). The PM of equipment maintenance is the advanced phase. Condition based maintenance is a kind of mode which inspects the equipment and analyzing the results and then decide whether the equipment are needed maintain. Condition based maintenance is the primary phase. The PM combines the skill realizing of condition-based maintenance with the equipment managing of the whole enterprise. Accordingly the PM can achieve the condition-based maintenance under the managing guidance and the equipment management under the support of the skills of faults diagnosis. So it is necessary to establish the managing information and decision-making supporting system of the equipment based PM.Firstly, in this paper the advantages and disadvantages of the three kinds of maintenance modes are analyzed and the PM is necessary during the development of the equipment management. And then the supports of the system and technology about the PM are set forth. Secondly, the developmental actuality of the managing information and decision-making support system based on the PM is introduced. And the foundation principles, methods, sorts and contents of the model are discussed. The fuzzy synthesis judgment arithmetic is adopted to build the model according to the actual instances and is introduced in detail. At last, applying the technology of fault diagnosis to the equipment managing and adopting fuzzy synthesis judgment arithmetic to decide the maintenance mode(heavy repair, light repair, item repair, daily repair) according to the equipment state and the other true producing state and then establishing the maintenance plan and the spare part plan, the managing information system and the decision-making support system of equipments based on the PM is designed and carried out which units the static management and dynamic management in this paper.
