Designing a Credit Risk Management Model in the Network of after-sales service companies Using Financial Components of After-Sales Services and Metaheuristic Algorithms(Case study: Saipa's after-sales service company(Saipa Yadak))

The type of customer service during the warranty is crucial for each complex. The purpose of customer service will be to meet the satisfaction of customers.

The intense focus on the quality of service causes the product to be valuable in terms of customers and their loyalty. Therefore, in this study, designing a credit risk management model for the for the Saipa Yadak Company and its Representatives Network using financial components of after-sales service and meta-heuristic algorithms was discussed. The sample studied in this research is the representatives of Saipa Company.The results showed that using financial components including, service cost, performance, good accounting, the amount of collateral and the amount of after-sales service agents have an impact on optimal credit risk management.
