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.
