Maintenance: The act of maintaining or the state of being maintained. The work of keeping something in proper condition; upkeep. Care or upkeep, as of machinery or property: With proper maintenance the car WILL last for many years. Any activity – such as tests, measurements, replacements, adjustments and repairs — intended to retain or restore a functional unit in or to a specified state in which the unit can perform its required functions. For material — all action taken to retain material in a serviceable condition or to restore it to serviceability. It includes inspection, testing, servicing, and classification as to serviceability, repair, rebuilding, and reclamation. Maintenance Management: Management characterizes the process of leading and directing all or part of an organization, often a business one, through the deployment and manipulation of resources (human, financial, material, intellectual or intangible). One can also think of management functionally as the action of measuring a quantity on a regular basis and adjusting an initial plan and the actions taken to reach one’s intended goal. This applies even in situations where planning does not take place. Situational management may precede and subsume purposive management. Maintenance management will therefore characterize the process of leading and directing the maintenance organization. Maintenance is defined as the combination of all technical, administrative and managerial actions during the life cycle of an item intended to retain it in, or restore it to, a state in which it can perform the required function (function or a combination of functions of an item which are considered necessary to provide a given service). We can define maintenance management as follows: All the activities of the management that determine the maintenance. Objectives or priorities (defined as targets assigned and accepted by the management and maintenance department), strategies (defined as a management method in order to achieve maintenance objectives), and responsibilities and implement them by means such as maintenance planning, maintenance control and supervision, and several improving methods, including economic aspects in the organization.
