PLANTMAINTENANCE





MEANING

Maintenance is a function which has not been

rendered obsolete by advanced technology , has

not faded away with the passage of time and has

not lost it’s stature in the industry, though other

functions have witnessed fluctuating fortunes

from time to time.



DEFINITION

A formal definition of maintenance is “…is that function of

manufacturing management that is concerned with the

day-to-day of keeping the physical plant in god operating

condition. It is an essential activity in every manufacturingestablishment , because it is very necessary to ensure the

availability of the machines, buildings, and other services

needed by other parts of the organization for the

performance of their functions at an optimum return on

the investment, whether this investment is in machinery,

materials, or employees.”





IMPORTANCE OF MAINTAINENCEMANAGEMENT

RELIABLE SERVICE: Dependency of service is one the

performance measures by which a company can distinguish itself

from others. To establish a competitive edge and to provide good

customer service, companies must have reliable equipments that

will respond to customer demand when needed. Equipments must

be kept in reliable condition without costly work stoppage and

down time due to repairs if the company is to remain productive

and competitive.



QUALITY ASSURANCE: Maintenance is an important factor inquality assurance which is another basis for successful competitiveedge. Inconsistencies in equipments lead to variability in productscharacteristics and result in defective parts that fail to meet theestablished specifications. Beyond just preventing break downs, it’snecessary to keep equipments operating within specifications thatwill produce high level of quality.

PREVENTION OF BREAK DOWN: Many of the manufacturingorganizations, particularly those with JIT (just-in time) programsare operating with inventories so low that they offer no protectionin the event of a lengthy equipment failure. Beyond the cost of idleequipment , idle labour and lost sales that can result from a

breakdown, there is danger of permanently losing market shares tocompanies that are more reliable. Maintenance function can help

prevent such an occurrence.







IMPACT OF POORMAINTENANCE

PRODUCTION CAPACITY: Machines idled by breakdowns

cannot produce, thus the capacity of the system is reduced.

PRODUCTION COSTS: Labour costs per unit rise because ofidle labour due to machine breakdowns. When machine

malfunctions result in scrap unit, labour and materials cost

increase. Besides, cost of maintenance which includes such as

costs of providing repair facilities, repair crews, preventivemaintenance inspections, spare parts and stand-by machines

will increase as machines break down frequently.



PRODUCT AND SERVICE QUALITY: Poorly maintained

equipments produce low quality products. Equipments that

have not been properly maintained have frequent break downsand cannot provide adequate service to it’s customers. For

example, air craft fleets of the airline, railway and road

transport services not maintained well can cause poor service

to customers.

EMPLOYEE OR CUSTOMER SAFETY: Worn out

equipment is likely to fail at any moment and these failures to

the workers, working in those equipments . Products such as

two wheelers and automobiles if not serviced periodically, can

break down suddenly and cause injuries to the users.



CUSTOMER SATISFACTION: When production equipments

break down, products often can not be produced according to the

master production schedules due to work stoppages. This will

lead to delayed deliveries of products to customers
