introduction
This standard provides a process for the rail transit authorities and their supporting industries to achieve the reliability of the corresponding methods.
Management of usability, maintainability and safety (represented by RAMS). This standard is based on the flow and examples of the RAMS requirements specification.
It is to promote consensus and management of RAMS.
At all stages of the rail transit application life cycle, the rail transit authorities and their supporting industries can systematically apply this standard.
Develop and meet the RAMS requirements for specific rail transit applications. The system grading method defined in this standard contributes to complex orbits
Evaluation of RAMS interactions between various elements of traffic.
In different procurement strategies, this standard will promote the cooperation between the rail transit authorities and their supporting industries to obtain the best
A combination of rail transit RAMS and fees.
The procedures specified in this standard assume that the rail transit authorities and their supporting industries have industry policies that stipulate quality, performance and safety. this
The method specified in the standard shall be consistent with the quality management content of the GB/T 19000 series of standards.

Security specifications and examples
1 range
This standard defines the various elements of RAMS (reliability, availability, maintainability, and safety) and their interactions.
The process of managing the RAMS based on the life cycle and its work, so that the contradictions between the various elements of RAMS can be effectively controlled and
management.
This standard does not specify RAMS indicators, quantities, requirements or solutions for rail transit specific applications, and does not specify security for the system.
demand. These should be specified in the RAMS sub-criteria for each specific application.
This standard applies to.
a) RAMS specifications and descriptions for all levels of rail transit applications and at various levels in this application; for example, from the entire track line
The main system on the track line and the independent or integrated subsystems and their components into these main systems,
Including the software included, in particular.
---New system;
---Integrated into a new system working in an existing system before the development of this standard, although it generally cannot be applied to existing systems
other aspects;
--- An update of an existing system prior to the development of this standard, although it generally cannot be applied to other aspects of the system.
b) All relevant phases of the life cycle in the application.
c) Use of the rail transit authority and its supporting industries.
Note. Application guidelines are given in the requirements of this standard.
