I have used Xpress in my dissertation and must interpret my results
properly. In the book as well as in the net I could find nothing the
fitting, for this reason the last attempt is to write here.

Please, explain me how to interpret the Rows (constrains), Columns
(variable), Non-zero elements as well as Simplex iterationens.
To better understanding of my question this is a part of my
sensitivity analysis (the network in B was reduced in contrast to A
and raises thus the total Costs, the solution is LP-optimum):

Result\ Test    A       B
Time (sek.)     0,9     0,7
Rows (constraints)      2.560   2.539
Columns (variables)     24.012  23.979
Non-zero elements       69.679  69.605
Simplex iterations      2.185   2.233
Total Value           5.314.782 5.635.651
