Linear/Integer Programming

Data for the example problem is added in the worksheet image shown below.

The algebraic model represented by the data is shown below.

The large upper bounds on the variables do not restrict their values since the machine constraints limit feasible production quantities to much smaller amounts. The model could have been constructed without the upper bound range defined. Since lower bounds are all zero, the range of lower bounds could also have been eliminated.
