Cellular Layouts


Every cell contains a group of machines which are dedicated to the production of a family of parts.
One of the problems is to identify a family parts that require the same group of machines.
These layouts are also called as group technology layouts.
The previous slide shows a facility in which three parts A, B, C flow through the machines.
The next slide provides the information in a matrix form which includes some other parts D, E, F, G, H.
The rows correspond to the parts and columns to the machines.
Just by interchanging rows and columns, eventually a matrix is obtained where the “X” marks are all concentrated near the diagonal. This matrix provides the cells. For example, parts A, D and F require Machines 1, 2, 4, 8 and 10 which forms a cell.
