method requires various technological processes for different parts of the final product; some of these
may comprise just two or three operations, whilst others may necessitate many more. A-type
manufacturing is usual in assembly facilities and sectors such as the heavy machinery, automotive or
aircraft industries (Inman 2011, Umble 1990).

The information system used for production planning and control within an A-type arrangement most
certainly includes BOM (Bill of Material) functionality with an emphasis on the accurate delivery of
components. Additionally, of prime importance is a high level of coordination between the purchase
and production processes. A technological layout of production facilities is typical for such
manufacturing, which increases demands on capacity planning. Therefore, methods based on Theory
of Constraints prove the most suitable, which respect limited resources.
5.3 T-type manufacturing and its requirements for planning software
Production denoted as type T contains many similar final products that have in common a limited
number of purchased or produced components. The technological processes used are generally very
similar and may consist of divergent points of assembly, at which two or more semi-finished products
are assembled into several variants of the final product. Normally, T-type manufacturing is adopted by
the electronics industry or for the production of consumer goods (Inman 2011, Umble 1990).

This style of production is sometimes referred to as modular. In terms of production take-up, it is
generally the ATO (Assembly-to-Order) or MTO (Make-to-Order) production system where push and
pull principles are combined. This condition should also be respected in the choice of supporting
software governing production planning and control. In T-type production systems it is very common
for materials and components to go missing between different orders. Therefore, it is important to
heed the software’s ability to reserve materials for certain orders or implement methods for
designated production with unique numerical identification (Seiban).
