Reliability,Availability,Maintainability and safety(RAMS)

For rail transit operators, good RAMS data performance represents lower operation and maintenance costs and reliable, safe and high-quality service. For system suppliers, RAMS data in line with the requirements represents high-quality systems and products, which is the basis for enterprises to participate in the competition.

RAMS evaluation during the system operation phase includes but is not limited to:

• Safety assessment of the operation and maintenance status of the subway line system that has been put into operation, including the assessment of its risk identification and control process, fault management and analysis process, etc.
• Evaluate the status of facilities and equipment of the subway line system that has been put into operation, including but not limited to the evaluation of the operation performance, status rating, service life and status range of facilities and equipment, and put forward suggestions for the optimization of facilities and equipment to improve the operation performance of the equipment.
