Information : Preventative Maintenance
Sandia National Laboratories (SNL) upgraded its preventive maintenance effort through the installation of a PC-based preventive maintenance program. Maintenance records were previously kept on a mainframe computer using SNL-developed software. The computer, which was labor-intensive to maintain, did not allow SNL to track maintenance costs effectively, did not have user definable maintenance scheduling capability, and did not contain maintenance procedures as part of the database.
In early 1994, SNL purchased commercial maintenance software from Datasystem Inc. of Greenville, SC, facilitating a change to a PC-based system that was more cost effective, permitted local shop control, and was integrated. This new integrated system supports maintenance scheduling, has specific/tailored maintenance instructions, and gives a history of maintenance activity. In addition, maintenance hours records can be maintained and queried, and reporting capabilities are available. SNL can now optimize the use of their maintenance staff and further reduce cost.
While the full benefits of this change to a PC based system have not yet been realized, Sandia has made significant improvements in maintenance processes. Among the benefits derived are:
Maintenance database developed for 735 machines Eliminated reliance on VAX computer
Replaced custom software with commercial software which has saved the Full Time Equivalent of 0.1 computer analyst time
Scheduled maintenance for 330 machines
Optimized the use of maintenance personnel.
