    Study Notes

    Linear Programming

    • Linear programming is used to maximize or minimize a linear function, subject to linear constraints.
    • The function to be optimized is called the objective function.
    • Constraints are limitations on the resources or other factors.
    • Decision variables represent the unknowns to be determined.
    • Constraints can be inequalities or equalities.
    • The feasible region is the set of all points that satisfy all the constraints of a linear programming problem.
    • The optimal solution is the point within the feasible region that gives the best value for the objective function.

    Example

    • A company makes two types of desks: red and blue.
    • The company has limited resources (wood, metal, and plastic).
    • The company wants to maximize profit.
    • Variables: $x_1$ = number of red desks and $x_2$ = number of blue desks
    • Objective function (profit): $P = 115x_1 + 90x_2$
    • Constraints:
      • $10x_1 + 20x_2 \le 200$ (wood)
      • $4x_1 + 16x_2 \le 128$ (metal)
      • $15x_1 + 10x_2 \le 220$ (plastic)
      • $x_1, x_2 \ge 0$ (non-negative)
