The work aims to study how to determine the recycling amount and price of discarded packages that could maximize the profits under the dynamic recycling environment, as well as the optimization of RL-MIS in the process of recycling discarded packages. Based on RL-MIS, the relationship between recycling amount, recycling price and each parameter was researched and the new DP model for the process of recycling discarded packages was constructed from the perspective of dynamic programming (DP). According to the historical data provided by Database, the supply curve equation obtained was used as a validation equation to test the operating results of the dynamic recycling model. The results obtained upon numerical examples showed that, the best daily recycling amount of discarded packages made of certain materials was 263.7 t and the best recycling price was 590.8 yuan/t. Combined with dynamic simulation results, it indicates that this model can obtain the optimal solution set of the recycling amount and price of the discarded packages through simulation under dynamic recycling environment. Results prove that using the DP model properly can effectively improve the earnings of discarded packages and reduce the recycling costs.
