*Engineering Maintenance ManagementMAINTENANCEOBJECTIVE:Understand and clarify the maintenance concept.

*A Maintenance definitionsWhat is Maintenance?

Maintenance, in terms of this century, means keeping equipment running or restoring it to operating condition.

*

*Maintenance is not about fixing things that break. Maintenance is about preserving, protecting, safeguarding, and looking after the very machines that make business possible.

*

*What is the mission of maintenance? The mission of the maintenance department is to provide excellent support for customers by reducing and eventually eliminating the need for maintenance services.

*What exactly is the purpose of the maintenance function?

*Maintenance in HistorySince the beginning of time, men have always felt the need for the maintenance of their equipment, even his most rudimentary tools. Most of the failures experienced have been a result of abuse, as it sometimes still happens.

First, they would only do maintenance when it was no longer possible to run it.

That was called Breakdown or Reactive Maintenance.

*Maintenance in HistoryIt was until 1950 that some groups of Japanese engineers started a new concept in maintenance that consisted on following the manufacturers recommendations about the care that should be taken in the operation and maintenance of the machines and devices.

That new trend was called Preventive Maintenance.

*Maintenance in HistoryThe times and needs changed, in 1960 new concepts were established, Productive Maintenance was the name for the new trend which determined a more professional approach. The assignment of a higher responsibility to all the people related to maintenance consisted of a series of considerations about the reliability and design of the equipment and the plant itself. The change was so profound that the term Maintenance was changed to Plant Engineering and the tasks to be performed included a higher understanding of the reliability of each element of the machines and installations in general.

*Maintenance in HistoryJust a decade later, the globalization of the marketplace created new, stronger needs for excellence in all activities. The World-Class standards In terms of equipment maintenance were understood, a dynamic system was created. TPM, is a continuous improvement concept that has proven to be effective, first in Japan and now back in America (where the concept was first created). It is about the involvement and participation of each and every one of the members in the organization towards optimizing the outcome of each piece of equipment.

*Maintenance in History

*Maintenance OrganizationOBJECTIVE:Understand the place of maintenance organization.Identify what is the organization roll?Responsibility and Cost involved with organization .

*Maintenance OrganizationComponents in maintenance organization:Resources: people, spares and tools (composition, location and movement)

Administration: a system of authority and responsibility for deciding what, when and how work should be carried out.

*Maintenance OrganizationWork planning and control system: a mechanism for planning and scheduling the work and feeding back the information which is needed if the maintenance effort is to be correctly directed towards its defined objective.Organization is basically concerned with matching resources and workload

*Maintenance OrganizationThe maintenance organization in any industry or business is faced with the same problems confronting manufacturing management in the production of a competitively priced product.

*Maintenance OrganizationHistorically the typical size of a plant maintenance group in a manufacturing organization ranged from 5 to 10 % of the operating force.Note that we have said the proportional size of the maintenance effort will continue to increase but not necessary the size of the maintenance organization.Experience has proven that giving workers more flexibility and authority is the long term solution to vast majority of production problems.

*Maintenance OrganizationCost ConsiderationsContrary to the opinion of many managers maintenance costs are highly controllable.This is because.For the most part maintenance is subjective. A great deal of maintenance or a minimal amount of maintenance can be performed with out ceasing to operate.Maintenance work is highly labor intensive and operations that are labor intensive can be controlled.

*Maintenance OrganizationThere are four fundamental costs associated with maintenance work. These are:Direct costs: are those costs required to keep equipment operable. This include periodic inspection and preventive maintenance, servicing costs, repair costs, and overhaul costs.Standby costs: the total costs of operating and maintaining standby equipment needed to be put in operation when a primary facilities are either under going a maintenance activity or are inoperable for some reason.

*Maintenance OrganizationThere are four fundamental costs associated with maintenance work. These are:Lost production costs: costs due to lost production because the primary equipment is down and no standby equipment is available.Degradation costs: those costs occurring in deterioration in life span of equipment resulting from inadequate and/or inferior maintenance.Controlling direct maintenance costs will permit reasonable control of the four fundamental costs that are related to maintenance work.

*Maintenance OrganizationThe responsibility of maintenance.It is the principal responsibility of maintenance to provide a service to the operation that enhances it is ability to make profit.These include providing a safe environment for all employees. A safe environment inevitably is a productive environment.Maximize the availability of production processes and equipment throughout the plant.Conserve energy usage.Conserve and control the use of spare parts and maintenance materials.Perform all maintenance activities when needed, utilizing qualified employees that perform in an efficient manner.

*Maintenance OrganizationThe place of maintenance in the plant organization.

The place of maintenance in the plant organization will vary with the size complexity, and product or products produced.

*Maintenance OrganizationThe maintenance organization.The structure of the maintenance organization depends upon both the size and the product of the enterprise.Perhaps the first consideration in planning a maintenance organization is the determination of whether to have centralized or decentralized maintenance.
