This general awareness has led to many new developments industrial products to preserve our world, and remanufacturing is one of such developments which is responsible for large energy savings, extending the lives of landfills, and cutting down on the amount of air pollution. Remanufacturing is a process where a particular product is taken apart, cleaned, repaired, and then reassembled to be used again. Many different types of products can go through this process, including auto parts, tires, furniture, laser toner cartridges, computers, and electrical equipment. In hybrid control systems for remanufacturing of used products and manufacturing of new ones, the two operations are not directly interconnected. The system produces both new product and remanufactured product. The customer can distinguish the difference between them. In this study, we considered the situation that customers may decide to buy a new product or a remanufactured one, i.e., there exists a substitution demand effect. We proposed a model to obtain the optimal production quantities for both the new product and remanufactured product to maximize the overall expected profits. The sensitivity analyses are performed by varying on various parameters to provide valuable insight to our model.
