Linear Programming Objective

The main goal of linear programming is to either maximize or minimize a specific value, like profit or cost.

Decision Variable

A decision variable in linear programming represents a choice or decision that a company can make.

Objective Function

The objective function in linear programming defines the goal of the decision-maker, specifying if they want to maximize or minimize something.

Constraints in Linear Programming

Constraints are limitations or restrictions placed on the decision variables in a linear programming model. They set boundaries on what is possible.
