11. Conclusions
In this research, the maintenance processes were
developed through literature review and expert
interviews. With the use of UML (unified modeling
language), a maintenance management system has
been developed. Through the analysis of the study, the
following conclusions can be made:
(1) The system provides track status to managers
who can make plans for maintenance and repair. It
also avoids dependence on the subjective personal
experience for scheduling maintenance;
(2) The system can learn from previous cases. The
accumulated experience is a good resource to train
new employee and assist the design of new
maintenance strategies. Through system parameter
settings, one can quickly calculate input data to
simplify the system and reduce human error;
(3) In this study, automatic inspection devices and
damage survey are used to collect track misalignment
data. The track inspection car EM80 automatically
checked track status, collecting real-time track
misalignment data;
(4) This study utilizes the original data access
format to record data. Data of same attributes are
recorded in same category. The result is a system that
is easy for update and maintenance. Accessed through
the database, the data can be easily used for statistical
analysis;
(5) Through GIS information, dangerous route
sections can be identified. This information can then
be used to call for early measures to avoid ballast
loss or landslides into routes to prevent possible
accidents.
