solution status} displays solution variable results**

It is very important to know whether a model has solved properly, and if
not, to locate where the problem lies.
The {Current solution status} sheet in the model workbook satisfies
this need. The two top matrices give
the final iteration values of the target and change variables for each time
period. The bottom two matrices give
the starting iteration values each time period. One can see a) how much the target
variables have changed each time period and b) how much the change variables
have changed. In this example, zeros in the top red matrix for all time
periods for all target variables shows that a satisfactory solution has been
calculated. While the target variables
were driven to zero from small non-zero amounts, the required changes in
change variables was very small (3 |
