Linear Programming: Evaluating the Objective Function at Each Vertex of the Feasible Region
In linear programming, the objective function is a mathematical expression that represents the goal of the problem. It is often denoted by the symbol P and is a linear combination of the decision variables. In this article, we will evaluate the objective function P = 50x + 80y at each vertex of the feasible region.
The feasible region is the set of all possible solutions to the linear programming problem. It is the area in the coordinate plane that satisfies the constraints of the problem. In this case, we have two constraints:
- 3x + 2y ≤ 30
- x ≥ 0
- y ≥ 0
To find the vertices of the feasible region, we need to solve the system of equations formed by the constraints. We can do this by graphing the constraints on a coordinate plane and finding the intersection points.
Vertex 1: (0, 0)
The first vertex is located at the origin (0, 0). To evaluate the objective function at this point, we substitute x = 0 and y = 0 into the equation P = 50x + 80y.
P = 50(0) + 80(0) P = 0
So, the value of the objective function at the first vertex is 0.
Vertex 2: (0, 15)
The second vertex is located at the point (0, 15). To evaluate the objective function at this point, we substitute x = 0 and y = 15 into the equation P = 50x + 80y.
P = 50(0) + 80(15) P = 1200
So, the value of the objective function at the second vertex is 1200.
Vertex 3: (6, 12)
The third vertex is located at the point (6, 12). To evaluate the objective function at this point, we substitute x = 6 and y = 12 into the equation P = 50x + 80y.
P = 50(6) + 80(12) P = 300 + 960 P = 1260
So, the value of the objective function at the third vertex is 1260.
In this article, we evaluated the objective function P = 50x + 80y at each vertex of the feasible region. We found that the values of the objective function at the vertices are 0, 1200, and 1260, respectively. This information can be used to determine the optimal solution to the linear programming problem.
In conclusion, evaluating the objective function at each vertex of the feasible region is an important step in solving linear programming problems. By doing so, we can determine the optimal solution and make informed decisions. In this article, we used the objective function P = 50x + 80y to evaluate the vertices of the feasible region and found the values of the objective function at each vertex.
