In recent years, with growth of competitive atmosphere, supply chain management, which is known as an effective element in economic and industrial life, is more considered as a very important issue. Logistics network design problem is a strategic decision that refers to the configuration of supply chain, and as the infrastructure in Supply Chain Management, has long-term effects on the company's tactical and operational decisions. In general, large amount of capital is allocated to the network design projects, and facilities that are already deployed are expected to be used for a long period of time. In this thesis a mixed integer mathematical model was developed in order to create the configuration, location and allocation of supply chain network. This model has considered forward and reverse flow together. The presented model is applicable to multi-product paradigm and has a limited capacity for potential sites for construction of the facility. One of the distinctive features of this model is that by taking profit into account, returns are collected and recovered as much as possible. Convertible products by applying the cost in the manufacturing sector, to produce other products on the market, are presented. Also, due to the uncertainty of the issue, especially customer demand parameter based model, a scenario was developed for the deterministic model, and the results can be used in conditions of uncertainty. In this thesis, and using the case study of Iran Milk Industry (Pegah), the model was solved, and the results were analyzed. The results determines the production of each production center of new raw material and returns, besides, collection centers and destruction was determined in this section. The sensitivity analysis indicates the expected model performance against the parameters of demand and the rate of return.
