Members of the audit pillar checklist should meet monthly to discuss the
MTBF goals and the monthly MTTR and other activities corresponding to
the Maintenance Management Program (Table 13.5).

13.4 Predictive maintenance using computational (fuzzy
logic) decision support tool in preload dispatch

An application of fuzzy logic is justified by the ability to anticipate the pos-
sibilities of making the predispatch time of the load on the operational tasks
of the equipment.
This study deals with the application of fuzzy logic to load dispatch, but
with a particularity that is to perform said predispatch of load taking into
account the technical state of the engines, evaluated by different variables
related to maintenance. In the first part the development of the fuzzy rules
and of the whole procedure of inference is exposed, and in the second part,
all the tests to evaluate the maintenance and the technical state of the motors.
