tenance. It was developed to provide supervisors at
each maintenance level with methods for effectively
and controlling shipboard
maintenance. It includes a maintenance data-collec-
tion system that is used to record important sche-
duled and corrective maintenance information, and
an electronic data- processing capability that is used
to retrieve this information for maintenance analysis.
The goal of PMS is maximum operational
efficiency of all equipments and the reduction of
equipment downtime, maintenance man-hours, and
maintenance costs. Even though the PMS provides
methods and resources to accomplish each goal, it is
not self-sufficient and does not replace the initia-
tive of maintenance supervisors or reduce the need
for technically competent personnel. The recording
and feedback of maintenance and personnel data
allow continuing management analysis and improve-
ment of maintenance methods and personnel use.
If the ships force accepts the PMS program and
makes fill use of its planning methods, the mainte-
nance system will promote confidence and reliability.
It will be capable of ensuring that the combat
systems will be available when they are needed.
Data gathered from the fleet show conclusively
that ships that adhere to their PMS schedule maintain
a significantly higher state of materiel readiness with
no greater maintenance manpower usage than ships
that do not. The SERT concept is designed to ensure
that the combat systems PMS is properly scheduled,
managed, and used.
The PMS program is essential to equipment
readiness. The primary ingredients of the PMS
program are as follows:
Comprehensive procedures for planned main-
tenance of the combat systems, subsystems,
Systems fault-isolation procedures.
Scheduling and control of maintenance task
Description of the methods, materials, tools,
and personnel required for maintenance.
Adherence to the PMS program will provide the
Improved confidence in systems maintenance
Reduced testing time
Elimination of redundant testing resulting
from lack of coordination
Detection of most malfunctions during sched-
uled maintenance events
The normal flow of events and requirements the
SERT should use in developing an integrated mainte-
nance schedule is illustrated in figure 4-5. This figure
shows maintenance management responsibilities and
the sequence of events that flows from the depart-
ment master and work-center PMS record books
(containing the maintenance index pages), through
the scheduling tools (cycle, quarterly, and weekly
schedules), to test actions, unscheduled maintenance,
and reporting. However, due to the shipboard envi-
ronment, it does not show the variants and con-
straints the SERT must consider in the quarterly,
weekly, and daily scheduling.
