The presented model involves several parts including market zone, disposal, collection, recycling, supply, manufacturing and distribution centers. Establishment of supply chain ingredients are considered as decision variables. Two objective functions are taken into consideration. The first objective desires to minimize the economic charges of the supply chain management in terms of establishment, transportation and market lost while the second one desires to maximize the attained market share. Any unmet demand will impose lost market charge to the system. A real case study has evaluated the outcomes of the proposed models. The results depict a novel way to provide a tradeoff between the objective functions values.
