It is often easier to learn from an example. Suppose we have the following model: We’ll standardize our model using the Big-M method as such: With being the “largest” number in .
Simplex standard form
Did you know?
The transformation of a linear program to one in standard form may be accomplished as follows. First, for each variable with a lower bound other than 0, a new variable is introduced representing the difference between the variable and bound. The original variable can then be eliminated by substitution. For example, given the constraint a new variable, , is introduced with http://www.linprog.com/
