Questions & Answers

Q: What is linear programming and how is it used?

Linear programming is a mathematical technique that allocates limited resources to achieve maximum satisfaction. It is used in various areas such as production mix, data analysis, transportation problem, and media selection.

Q: What are the assumptions of a linear programming model?

The assumptions are linearity (relationship between decision variables and constraints/objective is linear), divisibility (fractional values of decision variables are acceptable), certainty (values of parameters are known and constant), and negativity (decision variables are greater than or equal to zero).

Q: What are the components of a linear programming model?

The components include constraints (limitations or resources available), decision variables (representing the ultimate solution), objective function (mathematical representation of the objective), and non-negativity restrictions (decision variables are greater than or equal to zero).

Q: What is the standard form of a linear programming model?

The standard form consists of the objective function (maximization or minimization), constraints, and non-negativity restrictions.
