The Fuzzy Inference Application Uses the Fuzzy Sugeno Method in Determining the Inventory of Fruit Tea Drinks

Introduction

In the industrial world, we often face problems with uncertain answers, especially in inventory management. One effective method for analyzing systems that contain uncertainty is fuzzy logic. This study will discuss the application of Fuzzy logic using the Sugeno approach in solving the problem of the inventory of Fruit Tea drinks. The data used included information about the production, demand, and supply of Fruit Tea drinks from January to December 2017.

The Importance of Fuzzy Logic in Inventory Management

Fuzzy logic is a powerful tool for analyzing systems that contain uncertainty. In inventory management, fuzzy logic can help companies make more accurate and efficient decisions. By using fuzzy logic, companies can better plan their inventory needs, reducing the risk of excess or shortage of stock. This is especially important in industries where demand is unpredictable, such as the beverage industry.

The Fuzzy Sugeno Method

The Fuzzy Sugeno method is a type of fuzzy logic that is widely used in inventory management. This method involves several important stages, including fuzzification, rule formation, rule composition, and defuzzification. Fuzzification is the process of converting input data into a fuzzy form to facilitate analysis. Rule formation is the process of determining how input can be associated with output. Rule composition is the process of combining rules to produce more appropriate output. Finally, defuzzification is the process of converting fuzzy output into a crisp value using the weighted average value method.

The Application of the Fuzzy Sugeno Method in Fruit Tea Drink Inventory Management

The Fuzzy Sugeno method was applied to the data of Fruit Tea drink production, demand, and supply from January to December 2017. The results of the calculation showed that the supply of Fruit Tea drinks for January was 309 boxes. However, data from PT. Sinar Sosro shows a higher amount of inventory, which is 430 boxes. From this comparison analysis, it appears that the Fuzzy Sugeno method approach produces lower estimates compared to actual data. Nevertheless, the results of the Fuzzy Sugeno method are considered more optimal in the context of inventory planning, because it is able to provide a more realistic picture in the situation of uncertainty.

Advantages of the Fuzzy Sugeno Method

One of the main advantages of the Fuzzy Sugeno method is its ability to provide a more flexible solution in dealing with uncertain variables. Taking into account historical data and demand patterns, the company can better plan the inventory needed, reducing the risk of excess or shortage of stock. In addition, the use of this method can help companies in making data-based decisions that are more accurate and efficient.

Conclusion

From this study, it can be concluded that the application of the Fuzzy Sugeno method in Fruit Tea drink inventory management gives more optimal results despite differences with actual data. This method offers an effective approach in overcoming uncertainty and assisting companies in determining the right amount of inventory in accordance with market demand. Thus, Fuzzy logic is a very valuable tool in decision making in the industry, especially in inventory management.

Recommendations

Based on the results of this study, the following recommendations can be made:

The Fuzzy Sugeno method should be used in inventory management to provide more accurate and efficient decisions.
Companies should use historical data and demand patterns to better plan their inventory needs.
The use of fuzzy logic can help companies in making data-based decisions that are more accurate and efficient.

Limitations of the Study

This study has several limitations, including:

The data used in this study is limited to Fruit Tea drink production, demand, and supply from January to December 2017.
The Fuzzy Sugeno method was applied to a single case study, and its applicability to other industries and companies is not known.

Future Research Directions

Future research directions include:

Applying the Fuzzy Sugeno method to other industries and companies to test its applicability.
Developing a more comprehensive model of inventory management that incorporates fuzzy logic.
Investigating the use of other types of fuzzy logic, such as Mamdani fuzzy logic, in inventory management.

Conclusion

In conclusion, this study has demonstrated the effectiveness of the Fuzzy Sugeno method in inventory management. The results of this study show that the Fuzzy Sugeno method can provide more accurate and efficient decisions in inventory management. Therefore, the use of fuzzy logic in inventory management is recommended.
Frequently Asked Questions (FAQs) about the Fuzzy Sugeno Method in Inventory Management

Q: What is the Fuzzy Sugeno method?

A: The Fuzzy Sugeno method is a type of fuzzy logic that is widely used in inventory management. It involves several important stages, including fuzzification, rule formation, rule composition, and defuzzification.

Q: What is fuzzification?

A: Fuzzification is the process of converting input data into a fuzzy form to facilitate analysis. This involves assigning a membership value to each input data point, which represents the degree to which the data point belongs to a particular fuzzy set.

Q: What is rule formation?

A: Rule formation is the process of determining how input can be associated with output. This involves creating a set of rules that describe the relationships between the input and output variables.

Q: What is rule composition?

A: Rule composition is the process of combining rules to produce more appropriate output. This involves using a combination of rules to generate a single output value.

Q: What is defuzzification?

A: Defuzzification is the process of converting fuzzy output into a crisp value using the weighted average value method. This involves calculating the weighted average of the output values to produce a single output value.
