Objective: If important details such as sustainability and resilience are not taken into account in supply chains, the risk of potential threats increases. One of the crucial factors in increasing supply chain resilience is the management of cash flows, especially the management of payable accounts. Managing this factor will lead to better use of financial resources. This study creates a model to optimize the repayment schedules of payable accounts.
Methods: To optimize the model, a genetic algorithm was used and simulation was applied to calculate the suitability function. The objective function included the costs of stopping production lines, the costs of producing defective products, and the costs of borrowing for suppliers. The produced output determined the suppliers and the amount of payment to them in each period.
Results: Investigating the feasibility of applying the proposed method was the main finding of this study, and the obtained results proved the model as efficient.
Conclusion: The model used real data from the automotive industry and the results showed that the proposed model has the ability to reduce the costs up to 44.7%.
