Study On Pricing Decision Of Closed-loop Supply Chain Based On Recycling In Fuzzy Environment

With the rapid development of the economy in our country, people’sliving standard is gradually improving, and people’s demand is also increasing.At the same time, the consumption of resources has been constantly intensified,and the environment pollution towards people’s living has also been increased.In the face of this situation, enterprises begin to recycle and reuse thediscarded items, which make the traditional supply chain convert into theclosed-loop supply chain. The enterprises purchase the waste products fromconsumers through different recycling channels, and put these waste productsinto the manufacturing after the decomposition. During this process, thesupply chain has formed a cycle mode of production, which has broughtcertain economic benefits to the enterprise, decreased the environmentalpollution and brought certain social benefit at the same time.Firstly, the paper introduced the overseas and domestic research statusabout the closed-loop supply chain, and put forward the main problems of theresearch on the basis of previous studies, that was making a research on theprice decision about the closed-loop supply chain in the fuzzy environment,and describing the related theories of closed-loop supply chain and fuzzyenvironment.Secondly, the paper studied the optimal price decisions about theclosed-loop supply chain under different recycling channels, made research inthe angel of manufacturer and retailer under different recycling channelsanalyzed. The paper divided the recycling channels into manufacturers’recycle, retailers’ recycle and hybrid recycle. In every kind of recycling mode,we divided the game mode into manufacturer Stackelberg game, retailerStackelberg game and Nash game based on the different bargaining power ofthe manufacturer and retailer. The paper established fuzzy expected modes in every recycling mode by applying fuzzy set theory and game theory, and gotthe optimal pricing decision through solving fuzzy expected models. Throughnumerical simulation, we found that the manufacturers’ profit was themaximum in the hybrid recycling mode, and it increased with the recyclingand utilization rate of waste products.Finally, based on color television industry and taking Company C as anexample, the paper made a research on Company C’s pricing decision underdifferent recycling channels, and verified the study’s rationality and feasibilitybased on the analysis of Company C’s data.
