Introduction

In today's fast-paced and ever-changing business environment, companies are constantly seeking innovative ways to optimize their production processes and stay ahead of the competition. One such approach is the use of fuzzy logic, a powerful analytical method that can help overcome systems containing uncertainty. In this study, we applied the Fuzzy Mamdani method, also known as the Min-Max method, to determine the optimum number of newspaper production in the Medan Post General Daily. Our main objective was to explore the effectiveness of this method in overcoming uncertainty in production planning and to provide a more accurate and efficient approach to decision-making.

Background

Fuzzy logic is a mathematical approach that deals with uncertainty and imprecision in decision-making. It is particularly useful in situations where traditional binary methods are insufficient or unreliable. In the context of newspaper production, uncertainty can arise from various factors such as demand fluctuations, raw material availability, and production capacity constraints. By applying fuzzy logic, production managers can make more informed decisions and optimize their production processes to achieve better efficiency and profitability.

The Fuzzy Mamdani Method

The Fuzzy Mamdani method is a widely used approach in fuzzy logic that involves several stages, including:

Formation of the Fuzzy Set: This step involves the identification and definition of the fuzzy set for relevant variables, such as demand, inventory, and production capacity. For example, demand can be categorized as low, medium, and high.
Application of Implication Functions: After the fuzzy set is formed, the implication function is used to connect input (demand and inventory) to output (amount of production). At this stage, the rules that have been previously applied to get the desired results.
Rules Composition: In this step, the existing rules are combined to produce more accurate output. Each rule has a certain weight and effect on the final result.
Defuzzification: This process aims to change fuzzy output into a clear and understood value. In other words, this is a step to make the final decision based on the data that has been analyzed.

Implementation Steps

To implement the Fuzzy Mamdani method in determining optimum production in the Medan Post General Daily, we followed the following steps:

Data Collection: We collected data on demand, inventory, and production capacity for the Medan Post General Daily.
Fuzzy Set Formation: We formed the fuzzy set for relevant variables, such as demand, inventory, and production capacity.
Implication Function Application: We applied the implication function to connect input (demand and inventory) to output (amount of production).
Rules Composition: We combined the existing rules to produce more accurate output.
Defuzzification: We changed the fuzzy output into a clear and understood value.

Results

The calculation results using the Fuzzy Mamdani method showed that in August 2017, with 3,800 units of demand data and 327 kg of paper inventory, the optimum amount of production was 4,287.02 newspaper units. Meanwhile, for August 2019, with a request of 5,890 newspaper units and 562 kg paper inventory, the optimum amount of production was 6,550,673 units.

Analysis of the Fuzzy Mamdani Method

The Fuzzy Mamdani method is very relevant to be used in the context of optimum production determination, especially in the media industry such as the Medan Postal Daily. The newspaper production system not only depends on the demand factor, but also on the availability of raw materials and existing production capacity. In this situation, Fuzzy's logic is able to capture existing uncertainty and provide more appropriate decisions than binary conventional methods.

The Added Value of the Fuzzy Method

One of the added values of the Fuzzy Mamdani method is his ability to deal with complexity in decision making. In the context of newspaper production, uncertainty in demand and inventory can cause less optimal decisions if they only rely on traditional methods. By using Fuzzy logic, production managers can make better and more-oriented decisions, which in turn can improve efficiency and profitability.

Conclusion

Implementation of the Fuzzy Mamdani method in determining optimum production in the Post Medan General Daily shows that this approach is effective in overcoming uncertainty in the production process. With results showing the optimum amount of production based on existing demand and inventory data, this method is proven to provide significant benefits in production planning. In the future, it is hoped that this fuzzy method can continue to be used and further developed in various other industrial sectors to achieve more optimal results.
