With the progess of scientific and technological and living standards, consumers' requirements of products' diversity became more and more, which led to increasingly shorter product life cycle, more abandoned items and few resources, some resources even are in the face of threat and depletion. In order to meet the requirements of sustainable development and human society, how to maximize the use of resourecs has become the concerns of government, enterprise and academic. Under this situations, more and more countries demanded the manufacturer be responsible for the entire process life cycle, particularly the recycling of waste products. This paper primarily studied the maret strategy of remanufactured procucts based on the research results of the existing literature.The market strategy of remanufactured products was analyzed based on the demand of linear function, and the product life cycle and competitive environment were also considered. This paper studied the corresponding mathematical model and made a depth research and analysis.Firstly, the market strategy and profit of remanufactured products were studied, by calculating the profits under remanufacturing and not remanufacturing the critical conditions were got, the optimal price was also got, which provided the guidance for the enterprise to make a decision.Sceondly, the effect of product life cycle was also considered, using the rate of market change to characterize the market size and making a two-stage calculation, this paper founded that when the enterprise face a growing market, it shoulad focus on the production of new products rather than recycling procudcts(even the critical conditions was satisfied).At the same time, the optimal time for the enterprise to enter the market is the last period of the growing stage in the product life cycle.Lastly, the competitive environment was considerd, when the enterprise's quanity of the first stage satisfy a certain level, it would face the competitive of remanufacturer in the second stage, next, and the optimal reflection strategy of the enterprise was got. And by comparing the enterprise's profit under different conditions, new critical condition was obtained.The study of this paper provide a theory guidence for the enterprise to remanufacture, which have a great meaningful sense. |
