Introduction

In today's industrialization era, the application of supply chains is increasingly considered important. A well-functioning supply chain is not only an ideal thing, but also very beneficial for companies that implement it. However, in the process, supply chains often face various risks that can interfere with operational smoothness, one of which is a disruption in the transportation system. This study aims to offer mathematical models that can be used to analyze supply chains that experience unexpected disorders in transportation.

The Importance of Supply Chain Modeling

Supply chain modeling is a crucial aspect of modern business operations. It involves the analysis and optimization of the flow of goods, services, and information from raw materials to end customers. A well-designed supply chain model can help companies to minimize costs, reduce lead times, and improve customer satisfaction. However, supply chain modeling is a complex task that requires careful consideration of various factors, including transportation costs, inventory levels, and payment terms.

The Role of Two Echelon Trading Loans in Supply Chain Modeling

Two echelon trading loans refer to the practice of providing trade credit to retailers by suppliers, and then allowing retailers to offer a period of postponement of payments to their customers. This practice is common in many industries, including manufacturing and retail. In this study, we will explore the impact of two echelon trading loans on supply chain modeling, and develop a mathematical model that can be used to analyze the effects of these loans on cash flow and stability of the supply chain.

The Economic Production Quantity (EPQ) Model

The EPQ model is a widely used model in supply chain management that aims to optimize the production and inventory process. The model takes into account various factors, including production costs, inventory costs, and demand rates. In this study, we will develop an EPQ-based model that incorporates the effects of two echelon trading loans on cash flow and stability of the supply chain.

Model Analysis

The EPQ model has several advantages, including the ability to optimize the production and inventory process, and minimize total costs associated with storage and production. In every situation discussed, it allows decision makers to have a deep understanding of how the influence of the credit period and the delay of payment will affect cash flow and stability of the supply chain.

Case 1: T <T1 <T + T2

In this condition, retailers have more time to pay for suppliers and at the same time, can provide greater flexibility to customers. This allows retailers to increase sales without immediately spending capital for inventory.

Case 2: T <T + T1 <T2

Here, the retailer payment period is very tight, but retailers can still manage financing well. Although there is a pressure of the cash flow approach, retailers can use the period to maximize marketing and sales.

Case 3: T1 <T2

In this situation, retailers must be more careful because the period given to customers to pay beyond what is obtained from the supplier. This can cause risks, such as increasing uncollectible receivables, which can affect financial health retailers.

CLOSING AND NUMERIC SAMPLE

Finally, this research presents examples of numerical calculations that can help in applying this model practically. Through numerical simulations and analysis, it is expected to provide insight that is useful for decision making in the management of supply chains in dynamic conditions.

Conclusion

Through proper modeling and the application of risk in supply chain procedures, companies can increase operational efficiency and reduce costs. Thus, in-depth understanding of the credit period and payment regulation is an important key in maintaining the smooth and effectiveness of the supply chain.

Recommendations

Based on the findings of this study, we recommend that companies consider the following strategies to improve their supply chain management:

Implement two echelon trading loans: Companies can benefit from implementing two echelon trading loans, which can help to improve cash flow and reduce costs.
Optimize production and inventory levels: Companies can use the EPQ model to optimize their production and inventory levels, and minimize total costs associated with storage and production.
Monitor and analyze cash flow: Companies should regularly monitor and analyze their cash flow to ensure that they have sufficient funds to meet their financial obligations.
Develop a risk management strategy: Companies should develop a risk management strategy to mitigate the risks associated with two echelon trading loans, such as increasing uncollectible receivables.

Future Research Directions

This study has several limitations, and there are several areas for future research. Some of the potential research directions include:

Extension of the EPQ model: The EPQ model can be extended to include other factors, such as demand uncertainty and supply chain disruptions.
Development of a more comprehensive risk management strategy: A more comprehensive risk management strategy can be developed to mitigate the risks associated with two echelon trading loans.
Case studies: Case studies can be conducted to test the validity of the EPQ model and the effectiveness of two echelon trading loans in real-world settings.
