In recent years, for governments and industries waste management has become more important than ever due to legal requirements, economic profitability, environmental sensitivities and customer awareness development. The main objective of this article is to develop a mathematical programming model, in order to simultaneously improve the existing forward supply chain (SC) as well as to design reverse SC for the aim of collecting and recycling the used products, and also to coordinate the whole SC. The presented multi-objective model is solved by using revised multi-choice goal programming approach. The other objective of this work is to develop a more customer centric SC, which is successfully achieved by modeling the customer relationship management concept with strategic and tactical SC decisions. More importantly, the realization rate of the objectives, considering their importance to SC is shown to help senior managers in the decision-making process. The proposed model is designed for the new and emerging industry of recycling used tires in Iran, and is implemented by software with the cited industry data.
