Introduction

PT. Budi Raya Perkasa, a leading manufacturer of Maxi Coil spring mattresses, faces significant challenges in determining the optimal amount of production for various mattress sizes. The company produces three sizes: 80 x 200 cm, 140 x 200 cm, and 200 x 200 cm. Limited raw materials, market demand, machine capacity, and labor are key factors that must be considered in determining production strategies. To achieve company goals, PT. Budi Raya Perkasa needs to find the best solution in determining the amount of spring mattress production for each size.

The Cutting Plane Method: A Solution to Integer Linear Programming Problems

The cutting plane method is a powerful tool for solving integer linear programming problems, both pure and mixed integer. This method is specifically designed to add new constraints called gomory constraints when the variable value has not reached integers (still in the form of fractional values). The cutting plane method is an iterative process that adds new constraints to the original problem, gradually reducing the solution space until an optimal solution is reached.

Why is the Cutting Plane Method Ideal for PT. Budi Raya Perkasa?

The cutting plane method has several advantages that make it an ideal solution for PT. Budi Raya Perkasa:

Ability to handle integer constraints: The cutting plane method is specifically designed for integer linear programming problems, making it suitable for PT. Budi Raya Perkasa's production optimization needs.
Finding optimal solutions: The cutting plane method produces optimal solutions that maximize profits and minimize production costs, taking into account all existing obstacles.
Flexible and adaptive: This method can be modified and applied to various production optimization problems, allowing PT. Budi Raya Perkasa to analyze different scenarios and find the best solutions.

Understanding Gomory Constraints

Gomory constraints play a crucial role in the cutting plane method. These constraints are added to the integer linear programming model to "cut" the solution space that contains the value of variables that are not yet integer. This process is repeated until all variables reach the integer value, resulting in an optimal solution that meets integer limits.

Benefits of Implementing the Cutting Plane Method for PT. Budi Raya Perkasa

By applying the cutting plane method, PT. Budi Raya Perkasa can experience significant benefits:

Increasing production efficiency: Determining the optimal amount of production reduces waste of raw materials and labor, increasing overall production efficiency.
