Introduction

In the world of optimization, handling uncertainty is a challenge that is often faced. One of the approaches taken is robust optimization, which assumes that uncertain data has a limited convex and set that is known as a set of uncertainty. In this study, the determination of robust counterpart began with the assumption that the independent data set is in the set of uncertainty in the box interval. Robust optimization aims to produce a solution that remains effective despite uncertainty in data. This concept is important, especially in situations where the right information is difficult to obtain.

Basic Concepts of Robust Optimization

Robust optimization is a powerful approach to handle uncertainty in decision making. It assumes that the uncertain data is within a certain range or set, known as the set of uncertainty. In this framework, robust counterpart is expressed in the form of a set of uncertainty box intervals. This allows researchers and practitioners to calculate variability and fluctuations in data more systematically. The robust counterpart is a key concept in robust optimization, as it provides a way to model and analyze the uncertainty in the data.

Benders Decomposition Method

The formulation of robust counterpart can be explained as a major problem and sub-problem. This is where the Robust Benders decomposition method plays a role. This method is used to solve the problem of robust optimization in which the purpose of the objective is convex, and the limitations of the problem are cuasikonvex. By using this approach, we can find optimal robust solutions in a decent area for all data parameters involved. The Benders decomposition method is a powerful tool for solving complex optimization problems, and its application in robust optimization has shown promising results.

Numerical Simulation and Pom-QM Use

In this study, a numerical simulation was carried out manually to evaluate the results of the application of this method. The simulation process is then continued using POM-QM software. POM-QM is a useful tool in the analysis and problem solving of optimization, and its analytical ability facilitates the process to visualize and calculate the desired solution. The use of POM-QM software has been shown to be effective in solving complex optimization problems, and its application in this study has provided valuable insights into the behavior of the robust Benders decomposition method.

The Advantages of This Method

The advantage of the Benders decomposition method for robust optimization lies in its ability to separate complex problems into simpler parts. In this way, the problems faced are more easily managed and understood. In addition, this approach ensures that the solution obtained remains valid even when there are changes in uncertain data. The robust Benders decomposition method is a flexible and adaptable approach that can be applied to a wide range of optimization problems, making it a valuable tool for researchers and practitioners.

Conclusion

Development of Benders decomposition method for robust optimization provides an effective approach in dealing with uncertainty in decision making. By understanding the basic concepts and application of this method, researchers and practitioners can be better prepared to face the challenges that arise in data analysis and optimization in various fields. The combination of numerical simulations and advanced software such as POM-QM further strengthens the reliability and accuracy of the resulting solutions. This is an important step in creating a more adaptive and responsive system of changing conditions.
