A sustainable supply chain for organic, chemical agricultural products with public health and demand substitution considerations

摘要

In recent years, all countries around the world have been seeking ways to reduce Green House Gas (GHG) Emissions that have considerable effects on people and environment. One of the important effects of these emissions is the global warming. Therefore, all countries over the world should implement actions in order to reduce GHG Emissions. Organic agriculture or better to say use of organic products is one of the ways that can help to increase public health and balance the environment. The aim of this study is to develop a linear multi-objective mathematical model for a sustainable supply chain on a product with two different production methods. In this research, we consider demand substitution for chemical products and partial backorder for each of products. Deterioration occurs in the inventory level, and holding cost is assumed in a nonlinear form. We then present a numerical analysis to show the applicability of the model.
