Maintenance Management is concerned with planning
and controlling routine, planned and preventive
maintenance activities of an organization
Maintenance is concerned with day to day problem of machinery equipment in maintaining good working condition . It is very essential to ensure a continuous production flow by utilizing maximum capacity of plant

Minimizing the loss of productive time because of equipment
failure.
Minimizing the repair time and repair cost.
Efficient use of maintenance personnel and equipments.
To keep all productive assets in good working conditions.
To maximize efficiency and economy in production through
optimum use of facilities.
To minimize accidents through regular inspection and repair
of safety devices.
To minimize the total maintenance cost which includes the
cost of repair, cost of preventive maintenance and inventory
carrying costs, due to spare parts inventory.
To improve the quality of products and to improve
productivity.

Maintenance Prevention
It means that people waits until equipment fails and
repair it. Such a thing could be used when the
equipment failure does not significantly affect the
operation or production or generate any significant loss
other than repair cost.
It is a daily maintenance ( cleaning, inspection, oiling and
re-tightening ), design to retain the healthy condition of
equipment and prevent failure through the prevention of
deterioration, periodic inspection or equipment condition
diagnosis, to measure deterioration. It is further divided
into periodic maintenance and predictive maintenance
the equipment service life can be prolonged by doing
preventive maintenance.
Time based maintenance consists of periodically inspecting,
servicing and cleaning equipment and replacing parts to
prevent sudden failure and process problems. the basic
maintenance of equipment made by the users of it. It
consists of a series of elementary tasks (data collections,
visual inspections, cleaning, lubrication, retightening
screws,…) for which no extensive training is necessary.
This type of maintenance is the based on TPM (Total
Productive Maintenance).
A maintenance approach that involves testing and
monitoring machines in order to predict machine
failures. Repair is based on predicted time of functional
failure, generally by extrapolating from the results of
continuously monitored condition readings.
It improves equipment and its components so that
preventive maintenance can be carried out reliably. The set
of tasks is destined to correct the defects to be found in the
different equipment and that are communicated to the
maintenance department by users of the same equipment
Equipment with design weakness must be redesigned to
improve reliability or improving maintainability
It indicates the design of a new equipment. Weakness
of current machines are sufficiently studied ( on site
information leading to failure prevention, easier
maintenance and prevents of defects, safety and ease of
manufacturing ) and are incorporated before
commissioning a new equipment.
