Research On Packaging Size And Product Line Decision Of Reverse Supply Chain Based On Revenue Sharing Contract

Revenue sharing contract is a common contract in modern business society.It is signed by manufacturers and retailers before products are sold.Manufacturers will give retailers a lower wholesale price,so retailers will use lower retailers.The price enters the market in order to obtain greater profits,and finally the retailer will return part of its own revenue to the manufacturer;and the reverse supply chain of packaging waste means that the enterprise not only sells the product to consumers,but also recycles it from consumers.A series of activities for the remanufacturing of used products and packaging waste,including the acquisition,inspection,sorting and reverse logistics of waste packaging products.In these activities,companies reduce the pollution of waste to the environment,The remanufacturing process reduces the cost of the manufacturer;at the same time,today,all companies are pursuing a diversified product strategy.The packaging size of the product and the choice of product line are all decisions for consumers,manufacturers,and retailers.Had a significant impact.Therefore,the combination of revenue sharing contract,reverse supply chain and product packaging size has become a new field of academic research.Based on the above three points,the paper innovatively combines the three items of revenue sharing contract,reverse supply chain and product packaging size.In terms of the revenue sharing mechanism,manufacturers and retailers will sign revenue sharing contracts;in the reverse supply chain,a manufacturer recycling model,a retailer recycling model,and a thirdparty recycling model will be established.In terms of package size decision,both large and small package products are introduced,combined with factors such as unit size production cost,revenue sharing factor and unit recycling subsidies,to provide reference for companies in product size decision.The results of the study found that:(1)When the production cost per unit size increases,the optimal size of small packaging products increases under the recycling model of manufacturers and retailers,and the optimal profits of manufacturers and retailers also increase.The reduction in premium size reduces the profits of manufacturers and retailers.Under the third-party recycling model,the optimal size of large and small packages is reduced,the optimal profits of manufacturers and retailers are also reduced,and the profits of third-party recyclers are increased.(2)When the revenue sharing coefficient increases,the optimal size of large and small packages does not change under the recycling model of manufacturers and retailers,the profits of manufacturers increase,and the profits of retailers decrease.Under the third-party recycling model,the optimal size of large and small packages increases,the optimal profits of manufacturers and retailers also decrease,and the profits of third-party recyclers increase.(3)When the parameters meet a certain range,it is more beneficial for the overall profit of the reverse supply chain to select a product line with a small package size.(4)Manufacturers choose smaller package size product lines with less risk and greater optimal profits;retailers have no advantage in large package size and small package size product lines,and should avoid such revenue sharing and product recycling as much as possible Business model: Compared with products with small packaging sizes,third-party recyclers choose to recycle products with large packaging sizes for greater revenue.(5)When the unit recycling subsidy price increases,the recycling rate of waste products increases,the optimal product size increases,the optimal profits of manufacturers and retailers decrease,and the profits of third-party recyclers increase.The study made the following recommendations:(1)Manufacturers and retailers should increase the awareness of recycling and reuse of waste products and green environmental protection.(2)The government should guide enterprises to strengthen the recycling of waste,and at the same time formulate stricter laws to protect the environment.
