Optimizing Production and Inventory Control at Hera Bakery & Cakes Medan using Dynamic Programs

Introduction

Hera Bakery & Cakes, a small and medium business (SME) in Medan, Indonesia, faces a common challenge in managing production and inventory: balancing the need to minimize waste with the risk of disappointing customers and losing sales opportunities. To maximize profits and efficiency, Hera Bakery & Cakes requires a strategic approach to inventory control and production planning. In this article, we will explore the application of dynamic programs, a mathematical technique that helps make optimal decisions gradually, to optimize production and inventory control at Hera Bakery & Cakes.

The Problem of Production and Inventory Management

Production and inventory management is a critical aspect of any business, particularly for SMEs like Hera Bakery & Cakes. The company's goal is to produce and sell a wide range of baked goods, including cakes, pastries, and bread, while minimizing waste and maximizing profits. However, the company faces a classic dilemma: producing too much inventory can lead to waste and unnecessary costs, while producing too little inventory can result in customer disappointment and lost sales opportunities.

The Solution: Dynamic Programs

Dynamic programs, a mathematical technique that helps make optimal decisions gradually, emerge as a potential solution to this problem. Research conducted at Hera Bakery & Cakes aims to determine the total optimal inventory and compare the effectiveness of the dynamic program methods with the manual method applied by the previous company.

Methodology

The research methodology involved the following steps:

  1. Data Collection: The research team collected data on Hera Bakery & Cakes' production and inventory costs, including the costs of raw materials, labor, and storage.
  2. Dynamic Program Model Development: The research team developed a dynamic program model that takes into account the company's production and inventory costs, as well as the demand for its products.
  3. Simulation: The research team simulated the dynamic program model to determine the optimal production and inventory levels for Hera Bakery & Cakes.
  4. Comparison: The research team compared the results of the dynamic program model with the manual method applied by the previous company.

Results

The results of the research showed a significant potential in using dynamic programs to optimize production and inventory control at Hera Bakery & Cakes. Before the application of a dynamic program, the percentage of inventory costs reached 7.9%. After the application of a dynamic program, the percentage of inventory costs increased to 8.6%. Although there is an increase in percentage, the total value of inventory costs after using a dynamic program is even lower than the manual method.

Discussion

The increase in percentage of inventory costs may be caused by several factors, including:

*** Changes in Inventory Strategies: Dynamic programs might encourage more conservative inventory strategies by maintaining a slightly higher inventory to avoid shortage of stock. This might result in a higher percentage of costs, but minimizes the risk of running out of stock and loss of sales. ** Adjustment of Production Costs: Dynamic programs can consider more accurate production and storage costs, so as to produce a more realistic inventory cost calculation. ** Operational Efficiency: The application of dynamic programs has the potential to improve operational efficiency by reducing waste and optimizing resource use.

Conclusion

Although there is an increase in the percentage of inventory costs, a significant reduction in total inventory costs shows that the dynamic program has great potential to improve the efficiency and profitability of Hera Bakery & Cakes. This study provides important insights for Hera Bakery & Cakes and other small and medium businesses in implementing dynamic programs as an effective tool to optimize the production and inventory process.

Recommendations

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

  1. Implement Dynamic Programs: Hera Bakery & Cakes should implement dynamic programs to optimize production and inventory control.
  2. Conduct In-Depth Analysis: The company should conduct in-depth analysis and adjust dynamic program models with specific business conditions and needs.
  3. Monitor and Evaluate: The company should monitor and evaluate the effectiveness of dynamic programs in optimizing production and inventory control.

Limitations

This study has several limitations, including:

  1. Limited Data: The study was based on limited data, which may not be representative of the company's overall production and inventory costs.
  2. Simplification of Dynamic Program Model: The dynamic program model was simplified to make it easier to understand and implement.
  3. Assumptions: The study made several assumptions, including the assumption that the company's production and inventory costs are constant over time.

Future Research Directions

Future research directions include:

  1. Development of More Complex Dynamic Program Model: A more complex dynamic program model that takes into account more variables and assumptions should be developed.
  2. Implementation of Dynamic Programs in Other Companies: Dynamic programs should be implemented in other companies to determine their effectiveness in optimizing production and inventory control.
  3. Comparison with Other Optimization Techniques: Dynamic programs should be compared with other optimization techniques, such as linear programming and integer programming, to determine their effectiveness in optimizing production and inventory control.
    Frequently Asked Questions (FAQs) about Production and Inventory Control using Dynamic Programs at Hera Bakery & Cakes Medan

Q: What is dynamic programming, and how does it relate to production and inventory control?

A: Dynamic programming is a mathematical technique that helps make optimal decisions gradually. In the context of production and inventory control, dynamic programming can be used to determine the optimal production and inventory levels for a company, taking into account factors such as demand, production costs, and storage costs.

Q: What are the benefits of using dynamic programming in production and inventory control?

A: The benefits of using dynamic programming in production and inventory control include:

  • Improved efficiency: Dynamic programming can help companies optimize their production and inventory levels, reducing waste and minimizing the risk of stockouts.
  • Increased profitability: By optimizing production and inventory levels, companies can reduce costs and increase revenue.
  • Better decision-making: Dynamic programming can provide companies with a clear understanding of the optimal production and inventory levels, enabling them to make informed decisions.

Q: How does dynamic programming compare to other optimization techniques, such as linear programming and integer programming?

A: Dynamic programming is a more flexible and adaptable optimization technique than linear programming and integer programming. While linear programming and integer programming are more suitable for solving problems with a fixed number of variables and constraints, dynamic programming can handle problems with a large number of variables and constraints.

A: The limitations of dynamic programming in production and inventory control include:

  • Complexity: Dynamic programming can be a complex and time-consuming optimization technique to implement.
  • Data requirements: Dynamic programming requires a large amount of data to be effective, including information on demand, production costs, and storage costs.
  • Assumptions: Dynamic programming assumes that the company's production and inventory costs are constant over time, which may not always be the case.

Q: How can companies implement dynamic programming in production and inventory control?

A: Companies can implement dynamic programming in production and inventory control by:

  • Conducting a thorough analysis: Companies should conduct a thorough analysis of their production and inventory costs, including demand, production costs, and storage costs.
  • Developing a dynamic program model: Companies should develop a dynamic program model that takes into account the company's production and inventory costs, as well as the demand for its products.
