Abstract
In recent years, the environmental and social issues in developing and developed countries have a significant place. The attitude of the human societies to these issues has changed from need to demand. In some of industries such as healthcare, these issues have a stronger position. In this thesis, designing dual-channel networks in green and sustainable supply chains with regard to environmental and social along with economic concepts has been considered.
In the literature of designing green supply chains shows us the gap of developing mathematical models in the field of dual-channel green and sustainable supply chain network design. The approach implemented in this thesis is to consider the environmental and social issues along with the economic one in supply chains. According to the sensitivities available in healthcare that relates directly to the health of society and the environment, some patterns of regulations such as airborne particle concentrations and the amount of bacteria lives on the surface of products have been formulated. Two case studies, medical gauzes and bandages and surgical latex gloves are used in proposed models.
In this survey, 4 single-objective models with regard to ecomonic goal are developed to achieve a comprehensive multi-objective model that considers economoic, environmental and social aspects. To consider the green concepts, greenhouse gases emissions, water and wastewater management, waste management and the quality of products and processes are taken into accounts. Also, the balanced economic development of regions, employment and the health of consumers and labor forces based on the framework of European commission as the social responsibilities are considered.
One of the important issues in dual-channel networks is pricing. In this thesis, deterministic and stochastic pricing with regard to different channel prices are implemented. To solve the developed models, single-objective and multiobjective meta-heuristic algorithms are used. To validate the solutions, the meta-heuristic results are compared with those ones derived from the exact methods or other meta-heuristic algorithms in different problem sizes.
