Material requirements planning: system of linear euqations
The material requirements problem is solved via the solution of a set of linear
equations. The gozinto structure can be defined with the graph editor.
Symbols:
| i,j |
index of products |
| a(i,j)
|
number
of units of product i required to produce one unit of the immediate successor
product j (value of arc form node i to node j in the gozinto structure) |
| d(i) |
external demand for product i |
| v(i,j) |
total number
of units of product i required to produce one unit of product j |
| r(i) |
total requirement of product i |
