Blending problems usually require algebraic manipulation in order to write the LP in "standard form."

Question

Quizplus · Accepted Answer

Blending problems typically involve finding the optimal mix of different ingredients or materials to minimize costs or achieve certain characteristics. To formulate an LP for such a problem, we usually need to define decision variables, objective function, and constraints. In many cases, we need to use algebraic manipulation (e.g., substitution, elimination, or addition) to express the objective function and constraints in a standard form that contains only variables, constants, and coefficients of the same unit and sign. This makes it easier to apply LP solvers or algorithms to find the optimal solution.
