Maintenance has evolved over time from reactive repairs when equipment failed to preventive and productive maintenance approaches. Early approaches involved fixing devices only after they broke down. In the 1950s, preventive maintenance emerged where manufacturers' recommendations on equipment care and scheduled lubrication and inspections helped reduce damage. While this reduced downtime, preventive maintenance replaced some parts prematurely. In the 1960s, productive maintenance treated maintenance more professionally and assigned reliability experts to consider equipment design and component lifespan. This view of maintenance as plant engineering focused on optimal equipment performance and lifespan. Proper maintenance is crucial for quality of life, motivating the study of industrial maintenance engineering.

1. MAINTENANCE HISTORY AND EVOLUTION
Since the beginning of time, Man has always felt the need to keep your computer,
even the most rudimentary tools and devices. Most of the failures that were experienced
were the result of abuse and this is still happening today. At first it was only when it was
impossible maintenance continue using your computer. That was called "Break or
Reactive Maintenance"
It was until 1950 that a group of Japanese engineers began a new maintenance
concept was simply following the recommendations of equipment manufacturers about the
care that should be taken into the operation and maintenance of machines and devices.
This new trend is called "Preventive Maintenance". As a result, plant managers
were interested in having their supervisors, mechanics, electricians and other technicians,
develop programs to lubricate and making key observations to prevent equipment
damage.
Although helped reduce losses of time, the Preventive Maintenance was an
expensive alternative. The reason: Many parts were replaced based on time of operation,
while they could have lasted longer. Alsoappliedunnecessarilylonghours of work.
The times and needs changed in 1960 established new concepts, "Productive
Maintenance" was the new trend that determined a more professional. Highest
responsibilities were assigned to people related to the maintenance and considerations
were made about the reliability and the design of equipment and plant. It was a profound
change and generated the term "Plant Engineering" instead of "Maintenance", the tasks
included a higher level of knowledge of the reliability of each component of machines and
facilities in general.
The maintenance is very important, no maintenance would live with a better quality
of life. That's why I'm studying an industrial maintenance engineering
