PRINCIPLES AND PRACTICES OF MAINTENANCE PLANNING
1.1.1.Introduction
Maintenance Engineering is the discipline and profession of applying engineering concepts to the optimization of equipment, procedures, and departmental budgets to achieve better maintainability, reliability, and availability of equipment.
Maintenance engineering is the occupation that uses engineering theories and practices to plan and implement routine maintenance of equipment and machinery.
This must be done in conjunction with optimizing operating procedures and budgets to attain and sustain the highest levels of reliability and profit.
Maintenance engineers are often required to have knowledge of many types of equipment and machinery.
A person working in the field of maintenance engineering must have in-depth knowledge of or experience in basic equipment operation, logistics, probability, and statistics.
Experience in the operation and maintenance of machinery specific to a company's particular business is also frequently required.
Since the position normally requires oral and written communications with various levels of personnel, excellent interpersonal communication and participatory management skills are also
desirable.
Maintenance engineering positions require planning and implementing routine and preventive maintenance programs.
In addition, regular monitoring of equipment is required to visually detect faults and impending equipment or production failures before they occur.
These positions may also require observing and overseeing repairs and maintenance performed by outside vendors and contractors.
In a production or manufacturing environment, good maintenance engineering is necessary for smooth and safe daily plant operations.
Maintenance engineers not only monitor the existing systems and equipment, they also
recommend improved systems and help decide when systems are outdated and in need of
replacement.
Such a position often involves exchanging ideas and information with other maintenance
engineers, production managers, and manufacturing systems engineers.
Maintenance engineering not only requires engineers to monitor large production machine operations and heavy duty equipment, but also often requires involvement with computer
operations.
Maintenance engineers may have to deal with everything from PCs, routers, servers, and
software to more complex issues like local and off-site networks, configuration systems, end
user support, and scheduled upgrades. Supervision of technical personnel may also be require
Good maintenance engineering is vital to the success of any manufacturing or processing
operation, regardless of size.
The maintenance engineer is responsible for the efficiency of daily operations and for
discovering and solving any operational problems in the plant.
A company's success may depend on a quality maintenance engineering department that can be depended upon to discover systematic flaws and recommend solid, practical solutions.
