Total requirements matrix

The total requirement matrix is ​​one of the matrices from the Gozinto method and is z. B. used for material requirements planning. The overall matrix as a planning instrument, together with the gozintograph as a representation method, occurs primarily in companies or in processes that process a large number of materials and raw parts into a large number of intermediate and end products.

The total matrix G results mathematically as the inverse of the difference between the identity matrix I and the direct demand matrix D:

${\displaystyle G=(I-D)^{-1}}$
