In general manufacturing facilities, there is a general relation between product variety and production quality. In this short article, we will explain the relation between these two concepts in terms of manufacturing. Also, you can find lots of articles about manufacturing in Mechanical Base.
Product quantity values are generally classified into three groups;
- Low Production: Production of product quantity ranging from 1 to 100 in a year. Generally, this kind of manufacturing process or facility includes very complex products such as ships, airplanes, etc.
- Medium Production: Production quantity ranges from 100 to 10000 products/year. Car assembly line could be a very good example of them.
- High Production: Production quantity ranges from 10000 to millions of products/year. In these kinds of processes or manufacturing facilities, the produced products are very simple to produce. Serial production manner is valid extremely for this kind of product type.
So it is very basic to classify the production facilities according to their production rates in a year. So we can say that there is a strict relationship between the product type and product quantity.

What Is The Relation Between Product Variety And Product Quantity?
Product variety does not directly mean that the end product types are produced by a manufacturing facility or manufacturing process. It is directly related to which kinds of parts are produced on yearly basis in a manufacturing process or facility. So you could think that a production line of airplanes. The airplane manufactures only 50 airplanes/year. The product variety is one you can say. But it is not actually like that.
The airplane has lots of parts inside them. Some of them are produced in other manufacturing facilities and some of them produce in the related manufacturing facility. So all of them were assembled in the related facility. So there is the production of lots of kinds of products in one manufacturing facility which means product variety is very high. But also production quantity is very low. Which fits the above graph.
Also, think about the serial production of headlight glasses in a manufacturing site. It is very basic to produce part and there could be some kinds of facilities to produces these basic parts in a serial production manner. You can place this kind of manufacturing facility to low product variety/high production quantity.
The general relationship between product variety and production quantity is like that.
