Manufacturing and Productivity
Cellular Manufacturing is an approach
in which equipment and workstations
necessary to produce a product are
arranged closely together to facilitate
small lot continuous flow production.
The goal is to have the necessary
flexibility to produce a variety of low
demand products, while maintaining
the same productivity obtained with a
large scale production.

Zero Op-to-Op Transfer Times
All the operations necessary to produce a component or subassembly
are performed in close proximity. Near zero operation-to-operation
transfer times are achieved.
Cell designers achieve this through modularity
in both process design and product design.
The biggest challenge when implementing
cellular manufacturing in a company is dividing
the entire manufacturing system into cells.
The issues may be conceptually divided in the
"hard" issues of equipment, such as material
flow and layout, and the "soft" issues of
management, such as upskilling and corporate

Several Operators in Series
In a process with several operators, work is divided in small operations, so
that a group of operators team together to work at the same speed,
dividing the work load among them.
