**Assumptions for Resolving Linear Programming Problems**

There are certain assumptions related to the application of linear programming.

**Linearity**

In here, the objective function is directly proportional to individual constraints.

**Constant and Certain**

This states that the available resources are according to the requirements in the production of commodities, which is certain and remains constant.

**Variables which are positive**

Values of decision variables which are represented as solution in real life models are usually positive (non-negative). This is because values associated with physical commodities or products can never be negative. You can never state a production value as minus 5 ovens.
