| In recent years,the rapid development of technology and personalized consumer demand have accelerated the iterative speed of perishable high-tech product updates,resulting in a shortened life cycle of perishable high-tech products,which has also led to high productivity and low recovery rates of perishable high-tech products in reverse supply chains.In the recycling of perishable high-tech products,the timing of recycling,as the starting point of the reverse supply chain,is the source for manufacturers to increase reverse recycling profits.The recycling method is the subsequent process after the manufacturer recycles.This process is the main link that affects the cost input of the manufacturer,and it is an indispensable part of achieving value added in the reverse supply chain.Therefore,precise control of recycling timing and scientific decisionmaking on recycling methods are important means to help manufacturers improve economic efficiency.The reverse supply chain itself has a high degree of uncertainty and complexity.In the reverse supply chain,the recovery of perishable high-tech products is affected by factors such as technological innovation level,value perishability,and high residual value,presenting a certain degree of uncertainty and complexity,while increasing the decisionmaking difficulty of recovery timing and reuse methods.The generation of technological innovation and value perishability is a random process.The emergence of innovation and value perishability is uneven and randomly distributed on the time axis.Technological innovation and value perishability first cause dynamic changes in the recovery timing of perishable hi gh-tech products.Therefore,this paper uses the Wiener process in stochastic programming theory to analyze the impact of value perishability and technological innovation level on the manufacturer’s recovery timing,Discussed and constructed the recycling timing model under the influence of valueless perishability and technological innovation level,and finally verified the constructed recycling timing model through case analysis to finally obtain the recycling timing of perishable high-tech products.Then,in view of the impact of the recycling process after the timing of recycling is determined,this paper fully considers the level of technological innovation,the perishability of value,and various situations that are close to reality in complex practical environments,and constructs three decision-making models for recycling methods,namely,direct recycling and remanufacturing method,recycling and remanufacturing method,and recycling and direct resale method.A comparative analysis of the three recycling methods is conducted,This paper further explores the changes in revenue of manufacturers in three different recycling methods,and studies the impact of different value perishability and technological innovation levels on the selection of recycling opportunities and recycling methods.The main research conclusions of this paper are as follows:(1)The recovery time of perishable high-tech products is not only related to their own performance,but also affected by the degree of value perishability and technological innovation.The manufacturer can recycle products according to the threshold of performance reliability.When the manufacturer’s new products are highly innovative and the price of new products is low,the perishable high-tech products can be recycled as soon as possible to accelerate the pace of the replacement of perishable high-tech products,so as to make full use of its own resources and technical advantages.(2)The perishability of value and the level of technological progress have a great influence on the manufacturer’s decisionmaking in the reverse supply chain:in the recycling problem,affected by the perishability of value and the level of technological progress,the direct recycling method It is a feasible solution to improve the efficiency of the reverse supply chain and increase the environmental benefits for manufacturers to choose direct reuse after recycling.(3)The recovery rate of perishable high-tech products has the characteristics of dynamic evolution over time,and the manufacturer’s optimal recovery level and optimal pro fit are affected by the recovery rate.Stabilizes over time.The research results will help to expand the boundaries of recycling and reuse research in the existing reverse supply chain,in order to reduce the difficulty of manufacturers in making decisions about the timing and recycling methods of peri shable high-tech products,and provide a basis for the production of perishable high-tech products.Manufacturers of high-tech products provide service strategies and advice. |
