ABSTRACT
In current globe state, manufacturing companies are in need of sustaining their production level to meet the
customer demand. Whenever capacity problem arises, immediately they look for increasing overtime, number of shifts and
purchase new machines and equipments. As an alternative, they should focus on the better utilization of resources and
increasing performance of the existing machines which leads to an improvement in the equipment performance, reduction in
bottlenecks, decrease overall downtime, improve operator performance and minimize setup time and other major forms of
losses, thus enabling in decision on the investment of buying new machines. In this research, an attempt was made to
implement total productive maintenance to achieve overall equipment effectiveness (OEE) close to world class standards.
Result analysis shows that, downtime losses are not the only influencing parameter, but idle time of a machine is another
factor that adds to the variation in OEE. It is evident that the percentage OEE can be improved substantially by implementing
total productive maintenance lean tools such as Jishu Hozen, Kaizen etc in a manufacturing company. While calculating
OEE, the factors influencing it are identified and performance improvement measures are undertaken. From the observed
results, it was found that, the percentage OEE can be improved from 55.45% to 68.04% by implementing this technique in
medium scale industries.

INTRODUCTION
In present business scenario, every manufacturing company faces increasing competition and hence attempts to
be an effective, low-cost producer of their product with high productivity. Many times, attaining higher productivity
and bringing their product to the market with minimum cost is not possible due to various factors related to capacity
problems and problems related to performance of machines such as machine breakdown, minor stoppages, unplanned
maintenance, reduced speeds, quality rejects and rework. In such situation, an investment is made on buying new
equipment, increased shifts and increased working hours. This causes business executives to be sensitive about all
aspects of manufacturing operational costs. Hence lean tools must be used, as lean entails using less or the minimum of
everything required to produce a product or perform a service. Overall equipment effectiveness measures the gap
between the actual performance and the potential performance of a manufacturing unit. OEE encompasses three
measuring metrics such as availability, performance and quality. These help gauge the plant’s efficiency by
categorizing the key losses that affects the manufacturing process. Downtime reductions can be readily achieved by
using OEE to gain visibility into machine status and to perform root-cause analysis of problems.
