Abstract

                 In today’s competition time the common problem of
any industry is loss due to low productivity. Because now every customer wasn’t
high quality product at the lowest price, it doesn’t matter if it is the
product of lakhs of rupees of or it only cost 10 rupees. The important things
are quality and price. We can achieve the quality factor by increase facilities
but if the productivity is low then automatically the price of that product
will high. It is not good for competition with other product. But there are
some adverse effects and factors affecting parameters on productivity, this
paper is represent the over view on those information about productivity.

 

                                                    
                   

                Introduction

                     We generally consider
productivity as the ratio of the output product and the input we spent for
getting that output. We all know that input is the amount of product, but input
can be so many factors of production. Like man power, input material, Time,
etc. if we want to increase the productivity then we have to increase the
output for the same input or we have to decrease the input for the same output.
These can be done by implementing all lean tools. Reduction of wastes is equal
to increase in productivity

Literature
review

  

1)
Productivity growth and environmental efficiency of the nonferrous metals
Industry: an empirical study of China

This
paper investigated on the productivity growth of the chin’s manufacturing
industries, with considering the environment efficiency the
Malmquist productivity index (MPI), and the Malmquist-Luenberger productivity
index (MLPI). From 27 regions the data is collected. The efficiency of
productivity is higher at the east region then the efficiency of other region
the annual growth of MIP and MLPI is4.1% and 0.9%.. Nobody focus on effect of
environment change on productivity, everybody focus on the emission of energy,
china’s government should improve the mechanism to evaluate the emission of
co2. Technology improvement contributes more in increase in productivity.
Second the productivity growth of china was over estimated. This study fill the
gap between studies about china’s productivity growth in nonferrous metal
forming industries with respect to region.

 

2) Workforce Diversity: A Key to Improve Productivity

Diversity means similarity
and difference between employs in terms of age, cultural background, physical
abilities and disabilities, race, religion, gender, and sexual orientation. In
many multinational companies there are many employees are from different region
have different cultures, different languages so obviously they have different
mind sets so the way of problem solving is different. In this case many
multinational company have high problem solving techniques so they have high
efficiency of problem solving. Many researcher have mentioned that diversity in
company is very important but if it could not be managed properly then this can
be become big problem to handle the diversity for management and to employs
also. Because of different languages they can have some issues for working.
There are some solution for it like by using same language, encouragement to
employs, open all channels of communication between employs and employees

 

 

 

 

3)
Improving productivity using a multi-objective optimization of robotic

Trajectory
planning

 

In this article author have developed a new
algorithm for programing the automation of the robots for production in the
sense of kinematics and dynamics of robot arms to take minimum time
to perform robot tasks and avoiding collisions. Then the methodology allows
increasing the profitability of production lines by designing flexible
manufacturing systems. it allows firms to stay competitive in rapidly changing
markets, which also focus on high levels of quality and efficiency. Therefore,
this study’s algorithm probably improves the design and planning of the robot
tasks.

 

4) Productivity dispersion

 it investigate the dispersion of
productivity between branches of the same organization after taking data from
the thirty three branches of an US company they have seen that productivity
dispersion is argued to be largely illusory and follows from measurement error
in both inputs and outputs and second factor is measured productivity
differences are suggested to be caused by unobserved differences in factors
affecting productivity.

 

5)  Why are initial estimates of productivity
growth so unreliable?

 In this paper author says that the estimation
of productivity is not reliable. Two factors affecting productivity measurement
is (1) when production increases, inputs typically increase as well.
Productivity growth is therefore typically less variable than output growth, it
means that measurement errors will tend to be relatively more important.
(2) Revisions to published estimates of production and factor inputs
tend to be less highly correlated than the published estimates themselves. It
means when we start production the input will be high then the productivity
also will be high due to high output. So the constant productivity growth can
be seen.

 

 

 

6) The impact of job
stress and job satisfaction on workforce productivity in

an Iranian
petrochemical industry

In this study they have
focused on the relationship between job satisfactions, job stress with the
productivity. After the study the conclusion is that with higher work stress
the productivity of the worker will be less with respect to the productivity of
the worker with the high job satisfaction. This study is very important form
management to know supportive nature with the employs can improve the
productivity of organization

 

7)
Improving the productivity of sheet metal stamping subassembly Area using the
application of lean manufacturing principles

In this study they have
implemented lean manufacturing tools like 5s, poka-yoke, kizen etc. by these
tools the seven wastes of the production reduced so the working became so much
easier than the earlier method. So the productivity can be reduced by
implementing the lean tools at any firm.

 

8) Productivity
and Cycle Time Prediction Using Artificial Neural

Network

The aim of this study is to
develop a network which can predict the cycle time of high speed machining,
productivity can be increased by increase the speed of the process, the main
aim of this study is to increase the productivity and reduce the cost. Parts of
ANN for modeling and predicting the milling machine cycle time is made of the
aluminum ANN was designed the algorithm to involve increasing the cutting
regime while machining takes place.

 

 

 

9)
Trading with china, productivity increase job losses

It investigate the effect
of trading with china on the productivity and job losses, at this time the
china is the cheapest goods manufacturing country, so other countries are
importing the row materials from china so the labor work on those countries decreases
so the productivity can be increases by trading with china but the employment
will be decrease, and we can say that china is responsible for job losses in
many countries.

 

10) HIGH PRODUCTIVITY
IMPROVEMENT IN JFE FUKUYAMA NO.1 HOT STRIP MILL In this paper it is investigated that to increase productivity we have to
increase the capacity of the hardware. By increasing the capability of hardware
we can reduce the bottle necks of the process so that production can be easily
done. So the productivity will be increase. At the current example by
implementing this method they have found that the bottle neck was the reheating
furnaces, so by increasing the capability by implanting new burners they could
decrease the cycle time so productivity increased

 

Conclusion-

After study of these
research paper I can understand the importance of the productivity of any
organization to increase the profit and survive in the competitive markets, but
sometimes it can be harmful to the economy because of the heavy job losses and
increasing the unemployment. To increase productivity the best way to work is
implement lean tools like 5s, kizen, poke yoke etc. time study techniques also
can be used to reduce unnecessary motion or work, and it can be the root cause
o the less productivity.
