Research On The Optimal Inventory Strategy Of Perishable Products Under Carbon Policy

Nowadays,global warming caused by greenhouse gases is gaining more and more attention.Countries and organizations have adopted a series of policies to control the carbon emissions,such as carbon trading policy,carbon tax policy,carbon tax policy and carbon punishment policy.Carbon emissions has become an important reference for enterprises to make decisions.Perishable goods because of its perishable characteristics in the transport and storage process will consume more resources,so its impact on the environment is higher than the general product.Therefore,in the promotion of low-carbon economic environment,the study of carbon policy supply chain enterprises perishable inventory strategy is of great significance.This paper studies the inventory optimization of perishable products under different carbon policies.The demand rate is formulated as a linear function with respect to the current inventory level,and the deteriorating rates satisfy Weibull distribution with two-parameter.A nonlinear optimization model with equality constraint is constructed to Maximum the average total profit,and the existence and uniqueness of the optimal solution are proved.This paper compares with the traditional perishable inventory optimization model and the carbon model with the minimum carbon footprint as the target,and analyzes the effects of carbon trading policy and carbon tax policy on retailer's optimal inventory strategy.The main content of this paper is organized as follows:Inchapter 1,the main content is to introduce the background of the inventory optimization problem of perishable goods under carbon policy.The chapter reviews the current research situation at home and abroad,and shows the main research results of this paper.Inchapter 2,the main content is to study on the inventory optimization of perishable products under the carbon policy.The optimal replenishment strategy of the retailer is determined under the carbon policy and compares with the traditional perishable inventory model.Through the sensitivity analysis,the influence of the system parameters on the optimal profit,the optimal replenishment cycle and the carbon emission of the retailer will be studied.Inchapter 3,the main content is to study on the inventory optimization problem of perishable goods under the carbon policy when the out of stock is allowed.It will determine the optimal replenishment strategy for retailers under carbon trading and carbon tax,and analyze the impact of the two policies on retailers' optimal profits and carbon emissions,and determine the optimal carbon policy for the retailer.We will study the influence of the parameter on the optimal decision of the retailer sensitivity by the sensitivity analysis.
