Maintenance management with application Chapter | 13 341

In the lower left, we show the reliability analyses, which together with
the diagnosis allow us to know when it is possible for each motor to fail
to consider it in the predispatch of load.
The right part shows the application of the fuzzy logic, to perform the
predispatch of load, according to the fuzzy rules that meet the technical
state of the engines.

13.3 Fragments used for implantation end methodology
TPM program

This study presents a new solution proposal, which includes the predispatch
of load focused on the operational conditions of the machines using compu-
tational intelligence, specifically fuzzy logic. Such an implementation is
characterized by incorporating some innovations, such as good maintenance
management through TPM program for decision-making, considering perfor-
mance indicators of the generating units with respect to vibration, lubricating
oil, temperature, being it possible to say if the generating unit will operate
and maintain reliability or will get into maintenance due to poorly diagnosed
performance.
1. Pilar of specific improvements (Recommended group: Coordinators of
ME, MA (Plant Managers), MP and SMA):
Purpose: To maximize the overall efficiency of the equipment and the
operation through the analysis and elimination of operational losses
(Table 13.1).
2. Automatic maintenance pillar (Recommended group: Managers,
Supervisors and Operators of each Plant):
Objective: To enable operators to keep their workplaces clean,
organized, inspecting their equipment, following operating procedures,
lubricating, identifying abnormalities, labeling and attempting to
eliminate hard-to-reach places and sources of dirt (Table 13.2).
3. Planned maintenance pillar (Recommended group: PM Coordinator,
Service Managers and Supervisors and each Plant):
Objective: To create a maintenance management corporate model
for all engines and auxiliary equipment of the plants and external
clients to optimize interventions and reduce maintenance costs,
ensuring the performance of auxiliary engines and equipment
(Table 13.3).
4. Pillar of education and training (Recommended group: This pillar is
corporate and only depends on HR):
Objective: To support the other pillars, analyzing the qualification of
participants and the need for training. Responsible for communication,
TPM disclosure, event planning, compliance with the Basic Program
Guidelines to facilitate documentation, reduction of dissemination
costs and support materials (Table 13.4).
