  7. Abstract:
  8. Logistics includes the flow of goods, information and other sources between production and consumption node to meet the demand of customers. Basically, Logistics includes the integration of information, transportation and inventory. This study is in association with how to phase-out the old product when the new one is developed, and also is about how to manage the remaining inventory in a phase-out period focusing on such decisions as time and discount amount. Often in retailing system, old products have been phased out with an introduction of a new one by distributors. In order to sell this amount of products in a specific time period retailers need to create a mechanisim to phase-out the remaining products. In the first phase of this study new product development in a logistics sustem and also the phase-out process are being investigated. The MILP model is also developed to handle this problem. Then, the proposed model is solved using Genetic Algorithm and the results have been compared with the one solved by CPLEX software. Afterward, largescale problems are being solved using GA. In a next phase of this study, an optimized strategy introduced to reduce costs in the products phase-out process. To do so, a NLP model for multi period problem developed to maximaize the profit of discounted products
