Introduction

Linear programming is a powerful tool used in decision-making across various fields, including economics and engineering. However, in real-world scenarios, uncertainty often arises, rendering conventional linear models less effective. To address this issue, the application of fuzzy constraints, particularly in the form of Fuzzy Triangular numbers, has become increasingly important. Fuzzy triangular numbers can better represent uncertainty than traditional linear models, resulting in a more realistic solution. In this study, we introduce new methods that utilize the constraints of Fuzzy Triangular to improve problem-solving efficiency in bicriteria optimization.

The Importance of Bicriteria Optimization

Bicriteria optimization in linear programming is a technique used to achieve two goals simultaneously in complex problems. This approach is particularly useful in situations where multiple objectives need to be considered. By applying bicriteria optimization, decision-makers can obtain a more comprehensive understanding of the problem, enabling them to make more informed decisions. In this study, we focus on the application of bicriteria optimization with Fuzzy Triangular constraints to improve problem-solving efficiency.

Methodology

The methods used in this study involve the following steps:

Definition of Problems

The first step in this study is to define the goals and obstacles in the form of Fuzzy Triangular numbers. This involves identifying the key factors that need to be considered in the optimization process. By using Fuzzy Triangular numbers, we can represent uncertainty in a more effective manner, allowing us to obtain a more realistic solution.

De-Fuzzification

The next step is to use the De-Fuzzification algorithm to change the fuzzy number into a definite value. This is an essential step to ensure that every obstacle in linear programming can be expressed in the form of strict numbers. By applying the De-Fuzzification algorithm, we can obtain a clear and concise representation of the problem, making it easier to solve.

Application of Simplex Algorithm Parametric

In this step, we use the Simplex Algorithm Parametric to complete the sub-problems bicriteria. This method is used to convert every constraint that has been defuzzified into a fixed number, and the optimal solution is sought by considering the two existing criteria. By applying this method, we can obtain a more comprehensive understanding of the problem, enabling us to make more informed decisions.

Analysis of Results

Through the application of this method, we found that the use of triangular fuzzy numbers provides flexibility in dealing with uncertainty. The results of the simulation show that the solution produced using fuzzy constraints can provide better performance compared to conventional models. By getting two solutions (the best and worst), decision-makers can not only choose the most profitable options but also be aware of the risks that might occur. This adds to other dimensions in decision-making, especially in a very dynamic and uncertain environment.

Conclusion

Bicriteria optimization with triangular fuzzy constraints shows great potential in linear programming. The proposed method integrates uncertainty in the decision model and provides a more holistic solution. With advances in technology and methodology, it is hoped that linear programming can continue to adapt and be relevant in facing modern challenges. The implementation of this method in various industrial applications and further research can open new opportunities to improve operational efficiency and better decision-making.
