In recent years, remanufacturing, recycling and disposal of product after its end of life has been increasing attention of companies not only due to environmental regulations but it is great profitable in terms of cost. In this paper, a mathematical model was developed considering production of the products with remanufacturing facility for used products, collection/disassembly and disposal facility units for recovery of used products from the customer domain. The manufacturer serves a stationary demand by producing new items of product as well as by remanufacturing the collected used items of product or disposes them after analysis of used products at collection/disassembly units. The return rate of used item is formulated as a demand like function of purchasing price and accepted quality level of used products. In this work, particle swarm optimization is proposed to solve the model and validated with a cased study. The numerical results showed that a mixed strategy of pure production and remanufacturing is optimal with scope of environment regulations.
