Research On Equipment Maintenance Management Of ShenZhen-Hongkong Rail Transit Corporation

In recent years,China's urban rail transit has developed rapidly,and more than 30 cities have been opened for operation.The miles of operations and the number of cities opened in the next few years will continue to grow rapidly.Urban rail transit enterprises are typical asset-intensive enterprises.Improving equipment reliability,reducing the impact of equipment failures on operations and reducing equipment maintenance costs are important issues for rail transit companies.In order to study this subject,this paper studies the mature equipment comprehensive engineering,all production maintenance,preventive maintenance,especially reliability-centered maintenance and other equipment maintenance management theory system.The research methods used include literature analysis method,case analysis method,statistical analysis method,comparative analysis method and summary summarization method,and use professional tools such as human-machine method loop and analytic hierarchy process for analysis and research.Based on the research and analysis of preventive maintenance,reliability-centered maintenance and other mature equipment maintenance management theory,this paper studies the Shenzhen-Hong Kong rail transit company through case analysis,drawing on the industry benchmark – its parent company.The equipment maintenance management system established by more than 30 years of successful experience,and the application of the equipment maintenance management system developed by the parent company specifically for the rail transit industry.It is used for domestic urban rail transit enterprises,especially those that will be opened for operation.Based on the analysis of the current situation of equipment maintenance management,the company's current problem of insufficient equipment failure analysis,the high proportion of fault maintenance,and the failure to effectively apply the MMIS advanced maintenance strategy are analyzed through statistical analysis and comparative analysis.And through the tool of the man-machine method,the reasons for the problem are analyzed from the aspects of company personnel factors,equipment factors and working method factors.Based on this,the solution to the problem is proposed: the reliability centered maintenance work method is implemented to solve the problem of the company's equipment maintenance management.In order to ensure the smooth implementation of the solution,this paper studies the reliability centered maintenance work mechanism,and proposes specific measures such as establishing the RCM management organization structure,the scope principle of the company's implementation of RCM,and the RCM analysis workflow.Taking the gate as an example,the RCM analysis of the gate is carried out by using the proposed workflow to verify that the reliability-centered maintenance can solve the problems in the company's equipment maintenance management.And after implementation,it has obvious effect on reducing the proportion of brake failure maintenance,reducing equipment failure and reducing equipment maintenance costs.As a mature equipment maintenance management tool,reliability-centered maintenance has obvious applicability to improve the reliability of equipment in the urban rail transit industry and reduce the cost of equipment maintenance.This paper proposes that the implementation of the reliability-centered maintenance method can be used for reference by other urban rail transit enterprises,and it is a positive exploration for the implementation of reliability-centered maintenance for domestic urban rail transit enterprises.
