Assumptions and limitations of linear programming
Understanding the assumptions and limitations of linear programming is essential for applying this optimisation technique effectively in business decision-making. This lesson examines the foundational assumptions—such as fixed costs, constant unit variable costs, and known demand—that enable linear programming models to function, while exploring the real-world constraints and practical limitations that affect their reliability. Professionals gain insight into when linear programming is appropriate and where alternative approaches may be needed for accurate production planning and resource allocation.
