Designing a mathematical model of resilience supply chain and integrating financial and operational approaches

The purpose of this research was to design a five-level supply chain network by simultaneously taking into account the financial and operational dimensions as a systematic perspective. The innovativeness of the present research was in that it presented an integrated financial-operational approach in the resilience supply chain. This initiation was mathematically modelled by considering five levels of suppliers, factories, distributors, retailers, and customers in strategic and technical decision-making phases. Given the importance of equity versus accounting profit, the modeling aimed at maximizing the shareholders’ wealth. The suggested model was designed and tested by GAMS24 and CPLEX solver. The results of modeling and solving the numerical model indicated the importance of the role of financial dimension and simultaneous consideration of financial-operational dimensions in the mathematical model in obtaining sustainable competitive advantage. Moreover, the ability of the five-level supply chain was explained by the suitability of several criteria such as cost, capital structure, further increase of equity versus profit. In order to analyze the supply chain resilience, Iran Khodro Company, as the studied case, was tested and validated using the designed model. The results showed that applying the present research model can improve the supply chain resilience of Iran Khodro Company.
