Study On The Management Mode Of China Railway High-Speed' Fixed Equipment Comprehensive Maintenace

With the progress of China Railway High-speed'(CRH) construction, the length of CRH line has been increased continuously, the importance and workload of fixed equipment comprehensive maintenance have been increased at the same time. It has become a important topic to study the management architecture of CRH's comprehensive maintenance.Based on the theory of modern enterprise, this paper study the management architecture of CRH's comprehensive maintenance by borrowing JN and DB railway's experiences and by combining CRH's characteristics.Business process analysis is the prerequisite of management architecture design. In this paper, some conceptions such as competition prioprity, process structure and customer contact from business process theory are introduced at first, and then CRH comprehensive maintenance business process has been described in terms of China railway fiexed equipment maintenance management, fixed equipment types, comprehensive detection, key business process and so on, finally the characteristics of comprehensive maintenance has been given as follows:low-cost competitions prioprity, batch process, low customer contactness, low flexibility of process resource, and high density of process capital.The relation between detection and maintenance is the first consideration to design comprephensive maintenance management architecture. In this paper, two architectures (one separates detection from maintenance, the other integrates detection and maintenance) are compared in the view of transaction costs economics. At first some conceptions of transaction cost economics have been introduced briefly, the average production costs and average transaction costs of the separation architecture are compared with those of the integration architechure in the terms of asset exclusivity and uncertainity, lastly a novel management which add a detection quality center into the integration architecture has been brought up.In the condition of integration of detection and maintenance, in this paper, organization behavior theory has been used to analyze the technology kernel, technology support, administration support, high level management and middle level management of the comprephensive maintenance center. The organization structure serves the low costs competition strategy of comprephensive maintenance center.
