With the deterioration of the environment and the scarcity of resources and rising awareness of people's environmental protection,the strengthening of legal means and the promotion of government policies,re-manufacturing is increasingly attracting attention from companies and academia.The implementation of re-manufacturing strategies by enterprises is an important way to save natural resources and achieve social sustainable development.For most manufacturing companies that recycle and reprocess,in the course of their production and operation,the input for the operation mode of reprocessing were the used and used products.These old and waste products have many problems in quantity,quality,and technology.Stability is very difficult in management and production.In addition,it is sometimes difficult to meet the production demand in terms of production quantity,resulting in higher production costs for re-manufacturing,and the efficiency of enterprises is not very obvious.At this point,manufacturing companies need to make judgments on normal production and re-manufacturing production in order to determine the optimal production decision.First of all,we analyze the production process of the manufacturer under the traditional normal production model and the circular economy production model.Establishing the profit function model of the manufacturer,analyzing and solving the model.It can be concluded that the manufacturers have optimal production strategies in both modes.Further comparing the profitability of manufacturers under the two models,we concluded that when the parameters of production cost,demand status,and recycling processing meet certain conditions,the manufacturer decides which production method to adopt by comparing the profit size of the two produce models.Next,aiming at the uncertainty of the recycling and re-manufacturing model recovery process,in order to avoid this risk,two solutions are proposed: recycling outsourcing and mixed manufacturing,analyzing the production process of the two manufacturers separately,and establishing the optimal profit function model to analyzes the manufacturer's optimal production decisions and optimal profits underthese two scenarios.After solving the analysis,there are optimal production strategies in both cases.Finally,the above model was applied to the recycling manufacturing of the Y printer cartridge manufacturing company.The company's production and operation status and current problems were analyzed.The specific parameters of the manufacturer's production process were collected and numerical analysis was performed.For the company,in the production and manufacturing of ink cartridge products,the optimal production decision and profit of the normal production mode and re-manufacturing mode are compared,and finally it is concluded that when the market demand fluctuates less,due to the re-manufacturing production mode with cost advantages,the optimal profit of the circulatory re-manufacturing production model is higher than the optimal profit under the normal production model;as the standard deviation of market demand increases,the market demand fluctuates greatly,at this time the manufacturer bears the dual uncertainty of product recycling and processing about the market demand and the old,the best operating mode of usually production is higher than the optimal profit of the cyclic re-manufacturing mode.In the case of recycling outsourcing,the manufacturer can make the manufacturer's optimal profit higher than its own optimal profit when recycling,by formulating appropriate rewards and penalties.Therefore,the manufacturer can pass the re-manufacturing mode.Recycling outsourcing reduces the risk of recovery process uncertainty.In the case of mixed manufacturing,when the market demand variance is small and the demand is stable,the manufacturer's optimal profit is less than the optimal profit of the cyclical re-manufacturing model;As the variance increases,the market fluctuations intensify,and the optimal profit of hybrid manufacturing is higher than the profit of the cyclical re-manufacturing model,so mixed manufacturing applies to the situation when the demand fluctuates.
