Supply Chain

Considering the goals of sustainable development, numerous studies and research have been conducted in the field of supply chain sustainability. While some articles have addressed the social sustainability dimensions of the supply chain, there is a lack of integrated and comprehensive models to assess the performance of these chains in social sustainability dimensions, especially concerning decent work criteria. The present research aims to design a model for the maturity of decent work in the sustainable pharmaceutical supply chain. This research is an applied study from the perspective of objectives and descriptive research methodologically. The research population in the qualitative section consisted of experienced experts in the field of supply chain and decent work, and for this purpose, 15 individuals were selected and interviewed. After designing the initial model, in the qualitative section and initial screening of dimensions and components, 84 concepts remained in the model.

The supply chain of perishable products has high complexity due to the short lifespan of the products. For this reason, it is necessary to evaluate various issues in the supply chain such as location, inventory and logistics in an integrated manner by using flexible tools. The purpose of this research is to present an optimization approach based on event-factor-based discrete hybrid simulation for the integrated optimization of facility location, inventory control, fleet composition and routing in the supply chain of perishable products.The optimization process is performed using meta-heuristic algorithms. In order to conduct a case study, the supply chain of one of the largest producers of dairy products in the country has been considered, and due to the high demand and production of ice cream, this product has been considered as a perishable product of the supply chain. The results show that the integrated optimization of the research topic leads to a significant improvement in product waste, reducing the time of processing and delivering orders, and reducing the number of fleets.
