| The consumption level of the people is constantly improving under the stimulation of rapid economic development,and the consumption patterns that are affected by it are also more diversified.People also pay more attention to the quality of agricultural products from the basic problem of food and clothing,which promotes the rapid development of food cold chain logistics.As a problem closely related to life,more and more scholars have carried out research on food cold chain logistics.Through cost analysis,it can be seen that in the cold chain logistics operation process,the equipment part of the cold storage occupies an increasing proportion,and it can be known that the cost of the cold chain logistics can be reduced by adjusting the inventory of agricultural products.Therefore,if enterprises want to reduce the total cost,they must scientifically manage and control the key inventory problems in the cold chain logistics.In this way,it is possible to effectively control the inventory and reduce the rate of corruption of agricultural products to ensure the freshness of agricultural products to the greatest extent.At the same time,as the freshness increases,it will more cater to the needs of end consumers,and has achieved the goal of improving customer satisfaction and increasing customer loyalty.At the same time,environmental problems have become increasingly prominent in recent years.The state has also introduced a large number of corresponding policies to achieve green sustainable development.It has adopted a more reasonable Taiwan policy to constrain enterprises to jointly build a green economy.How to effectively combine carbon policy with the development of enterprises has always been a hot spot for the government and the public.The competition between enterprises is increasingly radiating competition between supply chains,so the trading environment is also from a simple level.The transaction evolved into a complex network model,so the carbon policy setting not only affects a single executor,but also affects the decision-making outcomes of all levels of participants in the supply chain network.Therefore,combined with the development orientation of the "13th Five-Year" agricultural products and the green sustainable development label,the carbon policy factors are introduced into the cold chain network equilibrium,and the equilibrium and application research of lowcarbon cold chain logistics network for agricultural products considering channel characteristics is proposed.This paper firstly uses the network equilibrium theory to build different optimization models for the cold chain logistics of single-channel and dual-channel sales models based on the time-sensitive cold chain network environment composed of multiple suppliers,distributors and retailers.The variational inequality theory is used to analyze the optimal behavior of decision makers at different levels of the cold chain system.Finally,the projection shrinkage algorithm is used to solve the problem and the sensitivity analysis of the cold chain system of the two channel environments is carried out.The main research work is embodied in the following four aspects:Firstly,the optimal behaviors of suppliers,distributors and retailers are described in turn for the single-channel and dual-channel sales models,and then the network equilibrium conditions of the entire cold-chain system are obtained,and the projections are used by using the variational inequality theory.The shrinking algorithm solves the entire network equilibrium.Secondly,for the cold chain logistics with strict time control,the freshness function is introduced to describe the change of quantity in the life cycle of agricultural products,comprehensively consider local environmental problems,and meet the central government’s counterpart by setting the maximum carbon emissions in the region.Carbon emission regulation converts carbon emissions into monetary costs,and then the impact of carbon policies on the cold chain system.Then,taking Shandong apple as an example,the model analysis was carried out to analyze the equilibrium state of the cold chain logistics network,and the impact of carbon limit,order batch and channel selection on transaction volume,average inventory,and overall system profit.Therefore,it has certain reference value for the enterprise to make the profit-maximizing order batch decision and the government’s carbon limit setting,which provides theoretical support for the enterprise to build a sustainable economic system.Finally,the main research work of this paper,the research limitations and the work that needs further work in the future are summarized. |
