In recent years, increasing costs and organizations concerns regarding funding and allocation of financial resources and the direct impact of these resources on supply chain’s decisions at all levels has led to modeling and optimizing financial flows within the supply chain. Also, financial factors are used to evaluating the performance of organizations and their business and credit conditions. So, the inability of organizations to manage and allocate these resources has led to financial and operational problems and diminish the credit position of organizations. Growing global market, increasing stakeholder involvement, financial regulations specific to each industry or country, the inseparable uncertainty of financial factors such as exchange rate and inflation rate, complexities in the field of financial flows and analysis of financial reports have led to decisions related to financial resources are always at high risk. Also, these decisions are simultaneously affected by the organizations, laws of every field of business, limitations of government and political restrictions, etc. So, based on the above problems and complexities, it is necessary to consider all the dimensions and the constraints of financial factors in the supply chain, both at the national level and international level.
This study aims to develop a mathematical model that simultaneously focuses on optimizing the financial and physical flows in an integrated manner and in the form of a global closed-loop supply chain. In order to evaluate the financial performance of the supply chain, the economic value-added index, and some financial ratios are used. The proposed model uses fuzzy CVaR cope with the uncertainty of parameters of this research. Also, the optimal level of credit sale, as a factor that affects the financial and operational decisions of the chain, has been investigated. To demonstrate the performance of the proposed model, the information of the Pegah dairy company Tehran plant has been used as a case study. The results indicated an improvement of more than 30,000 units in the financial structure by using the economic value added as an objective function, in comparison to the profit as an objective function. Also, increasing of more than 100 units of demand, as a result of increasing about 4% in the number of credit sales, is another significant result of this study.
