The approach appends slack, surplus, and artificial variables to the model where needed ... The following example shows how to find the minimum cost flow through a network using linear programming.

All references mentioned in Class 2 use linear goal programming (GP ... It seems most practical to let the model run for, for example, λ∈{0;0.1;…;1} and then judge the resulting diets ...

Data for a linear programming problem resembles the data for side constraints and nonarc variables supplied to PROC NETFLOW when solving a constrained network problem. It is also very similar to the ...

A more general approach is to format the problem as a standard linear programming model. That approach enables one to use the more general version of an LP package to solve a transportation problem.
