Research Of Vehicle Depot Equipment Maintenance Management

This paper expatiated the foundation position and important function of vehicle depot' s equipment management in railage system.Vehicle depot's equipment management was confronted with process reengineering in allusion to the variety of the railroad transportation system' s producing layout. The paper studied the 3 comparatively outstanding problems about vehicle depot' s equipment management combining the facts of the railroad transportation and developmental trend of modernize railage enterprises.1.By analysing basic principle of establishing equipment management organization, in allusion to the 3 equipment mainttenance modes of decentralization management,centralizing management and composite management. The paper adopted the analytic hierarchy process with safey analysis, put forward evaluating mathematics model of equipment maintenance organization, established judgment matrix and tested result, gave safety matrix, come into being judgment matrixs with safey analysis. The paper used adding priority average method for the group decision and gained result of comprehensive evaluation for 3 modes. The best management mode was gained and the example was gave.2. By analysing the problems of the equipment management of the current vehicle depot, the paper put forward the difference maintenance. According to the characteristics of every equipment , the paper established the evaluation system on the condition of equipment from the reliability,maintainability and economy. It used the fuzzy synthesis evaluation method and evaluated the function of equipment. It was made sure that the mode of equitment maintenance should be time-based-prevevtive maintenance,condition-based maintenance or run-to-breakdown maintenance.At the same time ,the paper adopted the grey GM(1,1)model to forecast the maintenance cycle with the time-based-prevevtive, the model was highly accurate and its predicted results were reliable, and the example was gave. According to insufficiency of equipment maintenance time which was induced by flexible production of the vehicle depot, the paper put forward that opportunistic maintenance should be adopted .For the 8 pipelines, the synchronous maintenance should be adopted. For the equipments which were controled by computer, run-to-breakdown maintenance should be adopted.3. By analysing the problems of the equipment maintenance's "3A" of the railway department, the paper introduced the theory of extenics, and established the evaluation system on the position of equipment maintenance which based on extenics. Matter element model was established and evaluation index was set off A～D grades according to the fact of the equipment maintenance. Extensional matter-element,classical matter-element were ascertained and the dependent function was established. According to the grades of positions which were ascertained by the dependent functions, the corresponding distribution coefficients were endued. According to the 2 parameters which were made up by the distribution coefficient and the money value of a distribution coefficient, fixing salary based on position was carried out.
