developing a multiproduct three-level cold supply chain considering quality evaluation function and pricing mechanism

Paying attention to cold supply chains is critical in light of rising global warming and public awareness of the issue. in addition, a lack of appropriate quality control in supply chains has resulted in significant waste in the industry. this research sought to create a three-level cold supply chain (firm, distribution center, and retailer) with a quality evaluation function. the chain has been modelled for a multiplicity of products and time periods. the parameters in this model are analyzed in three separate scenarios to reflect uncertainty. the model also includes direct delivery from the firm to the store. various factors can affect the quality evaluation variables, which in this model are assigned to two main parameters: temperature and humidity. the quality of the products in this model is used to estimate their selling price. due to the nonlinearity of the model, the baron approach is applied in this work.
