Improvement of configuration management in railway signalling system

Sammanfattning:
The railway network composed by different systems, such as
signalling, power supply, rolling stock and others. The signalling
system is used for control, supervision and protection of railway
traffic. Its reliability, maintainability and related maintenance
support affect the availability of the railway network. Often,
signalling system itself is considered as a system-of-systems
spread over a wide geographical area and consists of a large
number of items with different lifecycle. However, managing a
complex technical system with large number of items in different
lifecycle phases to achieve required availability is challenging.
One major challenge is to define and describe the structure and
relation between the system’s inherent items at any specific period
of time, i.e. the configuration of the system. The system
configuration is important during the design and manufacturing of
systems, but it is also essential during the utilisation and
retirement of a system. Furthermore, system configuration can be
considered as an essential data container to which other data
sources can be related, e.g. design data, reliability data,
maintainability data, operation data, and maintenance data. A
proper management of configuration data is highly important
during a system’s whole lifecycle, e.g. the railway signalling
system. Hence, the purpose of this paper is investigate how the
process of configuration management related to railway signalling
system can be improved through utilisation of Capability Maturity
Model Integrated (CMMI).
