Therefore, more and more manufacturers and companies are involved in the recycle of used products. This can explained by the following two main reasons: First of all, products with regeneration process are attractive to consumers who possess the concept of environmental protection. Secondly, on account of the restriction of law, manufactures have to effectively recycle and reuse the abandoned old or broken products in order to be beneficial to the environment.
Typical production systems have only new products in production line. When manufacturers collect used-products and perform the process of remanufacturing, they use production lines: for producing the new products and the remanufacturing products, respectively, and which are called “Hybrid system with remanufacturing.” It is desirable to establish a suitable strategy for such a remanufacturing system. In this paper, focus it on a hybrid remanufacturing system, we consider related costs with manufacturing and remanufacturing processes to construct a model in determining the optimal strategy of production. In addition, due to the variability of the collection of used-product and competition between the new and the remanufacturing products, we also consider the impacts of capacity constraint, product substitution and limitations of component availability. The model is utilized by the Lingo software to obtain the optimal new product production quantities and the collect rate of the used-product. The expected total profit and remanufacturing quantities can also be derived. Finally, sensitivity analyses are conducted on various parameters to gain insight into the proposed model.
