HOW TO UNDERSTAND THE CONCEPT OF PRODUCTIVITY ?

The increase of the world population causes the growth of the market.

However, this growth increased the number of who are sharing these limited resources.

The competitive environment in production has warmed up and continues to warm with the acceleration increasing .

With this competitive environment, it becomes more important to use the existing resources more effectively.

As known, effective use of resources means increasing productivity.

Productivity,is one of the important topics of engineering.

According to this, the number of engineers working on these issues ,like me, has increased.

I am the manager of @ARGE BİLİŞİM, which produces ‘ and quality measurement,

 increasing’ and provides services to companies by using industry, electronics and computer engineering sciences. 

In this article, I will try to explain “ and quality increasing” by making a general factory modeling without going into scientific details.

If you wish let’s start with the Arabic word ‘bereket’ which means abundance, which has been more frequently used in the past.

When we open and look at the dictionary, we will see words like “plentiness, abundance, ” facing the word bereket.

In the years when most of the population was envolved in agriculture, you will remember it to be used for the abundance of the product which people get from the field

With the majority of the agricultural sector workers migrating to cities and starting work in factories, this word has been replaced by ‘yield’ and then ‘productivity’.

In order to talk about productivity , we first need to consider a transformative or productive system.

Means that we will concretize productivity by taking into consideration converter structure which has input energy (or material),and transform it to another energy (or product).

As we talked about , the place where the subject will go will be factories, as you can imagine.

As you know, factories are the building rocks of the industry.

Generally established for profit (here the factories mentioned are non govenemental or non-profit organizations) and we can define the companies that produce goods as factories.

 First, let’s show these organizations a simple example model with an “input” and an “output”. After this model let’s give an example .

                             Form1: A general factory model with input and output.

Definition for a general system;

The amount of energy used (utilized),

After dividing the given (expended) energy after it multiplying by one hundred,

we describe as a percentage and benefit-We can explain it as a concept that gives us very important information about cost.

When we write as example the  formul of a lightning electric lamp (%)=will be (Light energy received / Electric energy supplied   ) x 100.

The point to be considered here is that the denominator and the denominator energy units are the same, because we express the  as (%).

The efficiency of systems on earth is less than 100%, in other words, there is no system with 100%  or more.

This means that; There is no perfect system on earth.

If you have noticed, I have described the perfect system as a 100% efficient system.

If there would be a perfect system on earth or if it could be invented we could say that all the wars would have ended and that people would become angels.

It means that if there is enough energy for everyone,  the sharing problem will disappear.

In fact, we have stated that the sum of energies received in any system is equal to the sum of the energies given.

The electricity energy given for our lamp sample is = light energy received + loss.

Heat energy for the lost lamp (our expectation from the lamp is light, not heat, so heat is lost for us).

When we think about the factory, there are possible losses in inputs such as energy, materials and labor.

 Thus, we can say that the most efficient factories are the ones with the least possible losses in inputs such as energy, materials and labor. Because the part of productivity in the formula for losses will decrease, economic productivity will increase.  When we define  for factories; through our general factory model   (%) = We can formulate it as (Input / Output) x 100 .

In other words, as purcentage we can define  as one of the most important data that shows our profit-loss situation by dividing the the output by the input multiplying to one hundred .

 Our sample factory, a garment factory producing one type trousers and examine its  in terms of labor.

                                          Figure 2: Sample of factory model

Default data

Number of workers=100 persons

Daily work duration= 540 Minutes

Daily trousers production quantity= 1500 Pieces

Trousers standart time = 25 Minutes

 Productivity(%) = (Quantity x Standart time / Daily work duration x Number of workers ) x 100

= (1500 x 25 / 540 x 100) x 100

=  69,44

Productivity of our sample factory is % 69,44 , the lost human energy is 100- 69,44 = % 30,56.

As can be seen here, we calculated the productivity by turning the inputs and outputs into the same units.

We can make the same calculation in other inputs and outputs so that the units are equal.

If you wish, let’s give an example of material  now.

Default data:

Trousers fabric quantity = 1,8 Meters

Fabric quantity used for trousers = 2 Meters

Productivity(%) = (Trousers fabric quantity / Fabric quantity used for trousers) x 100

= (1,8 / 2) x 100

=  90

Our sample factory fabric productivity is % 90,if the lost fabric percentage  100-90= % 10.This way we calculated the  of the material used.

In terms of production sector, national and international trade competition is increasing with an increasing momentum every day.

The prerequisite for getting ahead and making a difference in this competitive environment is to increase productivity.

One of the most important (perhaps the most important) issues that our business people need for increasing and maintaining their competition is to continuously measure and increase their productivity.

I will be happy if writing this article about productivity would be useful.
