Optimal Strategies of Different Quality Level of Returned Products for Manufacturing / Remanufacturing Enterprises Under Carbon Tax

WANG Xin-yue;GUO Jian-quan;Business School,University of Shanghai for Science and Technology;  
Considering the circumstances of different quality level of returned products,optimal operation strategies of different carbon taxes were investigated for manufacturing / remanufacturing enterprises in a multi- period closed- loop hybrid manufacturing / remanufacturing system,where the demand was satisfied by manufacturing from raw materials as well as remanufacturing from returned items into as- new products. A model was developed to minimize the total cost of the system considering carbon emissions for manufacturing / remanufacturing products. It was assumed that the quality of returned products was set to be standard normal distribution. Buyback cost,remanufacturing cost and return rate were negative exponential function of quality level of returned items. A numerical example was used to verify the validity of the model by adopting Genetic Algorithm( GA) and Particle Swarm Optimization( PSO) algorithm. The results showed that the enterprises could arrange reasonably the number of remanufacturing and manufacturing frequency ratio of different quality level of returned products to minimize the total cost,the rational number of remanufacturing and manufacturing frequency ratio could reduce the total cost under different carbon taxes. A good reference could be provided for minimizing the total costs of the system under different quality level of returned products considering the carbon emission for enterprise as well as initiating a reasonable carbon tax policy through this research.
