Unit production is a type of production characterized by unit (piece) manufacture of varied and changing production. Production planning is essential for all types of products and services classified as such.
Unit production includes producing unique machine tools and metallurgical and mining equipment and bespoke furniture, elements of the interior, and other types of custom-made orders. As distinguished from mass production and serial production, unit production allows for a non-regulated movement through working locations and a free working rhythm. Working areas are usually provided with general-purpose equipment. The production process of each order is designed individually. The unique nature of the orders requires the labour of more highly skilled “general” workers. The use in unit production of specialized equipment and devices and the frequent changes from one item to another cause relatively large workforce expenditures in setting up operation and longer production cycles.
