Building an RCM System for Urban Rail Transit Based on Digitalization
With the high-speed development of the urban rail transit,the business subjects begin to change from manufacturing to maintenance and the concern on comprehensive cost of product change from manufacturing cost to life cycle cost.Based on the huge proportion of the maintenance cost in the life cycle cost of the urban rail transit,building a Reliability-Centered Maintenance(RCM)system has become an important way to continually optimize the maintenance cost for the moment.Compared with the RCM analysis simply relying on off-line data,now along with the digital and intelligent construction of the urban rail transit,an intelligent RCM platform can be built based on digitalization to integrate design,production,manufacturing,operation and maintenance and realize the interaction of life cycle data.The digital platform can not only provide the basic RCM analysis function,but also support users to progressively confirm the repair strategy and make the multidimensional qualitative analysis and the multidimensional quantitative evaluation and analysis.Based on digitalization,it can establish a management system integrating data,personnel and system so as to provide users with better middle and long-term repair strategy,and finally,comprehensively reduce the life cycle cost(LCC)of the urban rail transit and promote the construction of the"system+"system.
