Introduction

Determining the amount of production is a crucial task for companies, as it can have a significant impact on financial losses due to excess or lack of production. Uncertainty in production is a common challenge that companies face, and it can be caused by various factors such as changes in market demand, raw material availability, and production capacity. One method that can help overcome this uncertainty is Fuzzy logic, a system that mimics the process of human decision making using the concept of the fuzzy set.

Fuzzy logic is a powerful tool for handling uncertainty and imprecision in decision-making processes. It has been widely used in various fields such as engineering, economics, and management. In this study, a comparison of two popular Fuzzy inference systems was carried out, namely Fuzzy-Mamdani and Fuzzy-Sugeno, to see their effectiveness in predicting the amount of production.

Fuzzy-Mamdani Method

The Fuzzy-Mamdani method is a type of Fuzzy inference system that uses a fuzzy set to represent the data membership in a range of values. This method is based on the work of Ebrahim Mamdani, who introduced the concept of Fuzzy logic in the 1970s. The Fuzzy-Mamdani method has several stages, including fuzzification, rule base, and defuzzification.

Fuzzification: This stage involves transforming the input data into a fuzzy set, which is a representation of data membership in a range of values.
Rule base: This stage involves creating a set of rules that define the relationship between the input variables and the output variable.
Defuzzification: This stage involves converting the fuzzy output into a crisp output, which is a numerical value.

The Fuzzy-Mamdani method uses a centroid method to defuzzify the output, which is the midpoint of the area under the fuzzy set curve.

Fuzzy-Sugeno Method

The Fuzzy-Sugeno method is another type of Fuzzy inference system that uses a linear function to represent the data membership in a range of values. This method is based on the work of Mitsuo Sugeno, who introduced the concept of Fuzzy logic in the 1980s. The Fuzzy-Sugeno method has several stages, including fuzzification, rule base, and defuzzification.

Fuzzification: This stage involves transforming the input data into a fuzzy set, which is a representation of data membership in a range of values.
Rule base: This stage involves creating a set of rules that define the relationship between the input variables and the output variable.
Defuzzification: This stage involves converting the fuzzy output into a crisp output, which is a numerical value.

The Fuzzy-Sugeno method uses an average centralized method to defuzzify the output, which is the average value of all linear functions that meet the rules.

Performance Comparison

The performance of the Fuzzy-Mamdani and Fuzzy-Sugeno methods was compared using actual and evaluation data with Mean Squared Error (MSE). The results showed that the Fuzzy-Mamdani method is more optimal in determining the amount of production. This shows that the fuzzy-mamdani method has better ability to model uncertainty and produce more accurate production predictions.

Conclusion

The choice of the right fuzzy method to determine the amount of production depends on the data characteristics and needs of the company. For data that contains high uncertainty and requires a more complex representation of fuzzy, the fuzzy-mamdani method can be a better choice. On the other hand, if the data is more certain and its needs are simpler and more efficient models, then the fuzzy-sugeno method can be the right choice.

Recommendation

Evaluation of data types and company needs: Before selecting methods, consider the characteristics of data and special needs of the company, such as the level of uncertainty, level of complexity of the model, and computing requirements.
Consider the use of the Hybrid method: Combining several fuzzy methods, such as using the fuzzy-mamdani method to model uncertainty and fuzzy-sugeno to speed up calculations, can produce more optimal results.
Conducting sensitivity analysis: Analyzing output changes to changes in input can help increase model accuracy and optimize fuzzy parameters.

Future Research Directions

This study has shown that the Fuzzy-Mamdani method is more optimal in determining the amount of production. However, there are several areas that require further research, such as:

Development of new fuzzy methods: Developing new fuzzy methods that can handle complex data and uncertainty is an area that requires further research.
Application of fuzzy methods in real-world problems: Applying fuzzy methods to real-world problems, such as production planning and inventory control, is an area that requires further research.
Comparison of fuzzy methods with other methods: Comparing fuzzy methods with other methods, such as machine learning and statistical methods, is an area that requires further research.

In conclusion, this study has shown that the Fuzzy-Mamdani method is more optimal in determining the amount of production. However, the choice of the right fuzzy method depends on the data characteristics and needs of the company. Therefore, it is recommended that companies consider the characteristics of data and special needs of the company before selecting methods.
