【摘要】：现如今,温室气体造成的全球气候变暖问题越来越受到人们的重视。各个国家和组织通过制定一系列政策来控制碳排放量,比如碳交易政策、碳税政策、碳限额政策和碳惩罚政策。碳排放量已成为企业进行决策的一个重要参考依据,易腐品由于其易变质的特性在运输以及存储过程在中会消耗更多的资源,从而对环境的影响要高于一般性产品。因此,在倡导低碳的经济环境下,研究碳政策下供应链企业的易腐品库存策略是有重要意义的。本文研究不同碳政策下易腐品的库存优化问题。当需求率为当前库存水平的线性函数,产品的变质率服从两参数的Weibull分布时,建立了以最大平均总利润为目标的非线性约束优化问题,证明了最优补货周期的存在性与唯一性。通过与传统的易腐品库存优化模型以及以最小碳排放量为目标的碳模型进行比较,分析了碳交易政策和碳税政策对零售商最优库存策略的影响。论文内容安排如下:第一章,介绍碳政策下易腐品库存优化问题的研究背景,对国内外相关研究现状进行评述,介绍本文的主要研究成果。第二章,研究不允许缺货时碳政策下易腐品的库存优化问题。在碳政策下确定零售商的最优补货策略,并与传统易腐品库存模型进行比较。通过灵敏度分析,研究系统参数对零售商最优利润、最优补货周期以及碳排放量的影响。第三章,研究允许缺货时碳政策下易腐品的库存优化问题。确定碳交易和碳税碳政策下零售商的最优补货策略,分析比较两种政策对零售商最优利润和碳排放量的影响,确定对零售商有利的碳政策。最后利用灵敏度分析研究参数对零售商最优决策的影响。
[Abstract]:Nowadays, people pay more and more attention to the problem of global warming caused by greenhouse gases. Countries and organizations make a series of policies to control carbon emissions, such as carbon trading policy, carbon tax policy. Carbon capping policies and carbon penalty policies. Carbon emissions have become an important reference for enterprises to make decisions. Perishable products, because of their perishable properties, consume more resources in transport as well as in storage processes. The impact on the environment is therefore higher than that of general products. Therefore, in the context of a low-carbon economic environment, It is important to study the perishable inventory strategy of supply chain enterprises under carbon policy. In this paper, we study the inventory optimization of perishable products under different carbon policies. When the demand rate is a linear function of the current inventory level, The nonlinear constrained optimization problem with the maximum average total profit as the goal is established when the deterioration rate of the product is distributed from the Weibull distribution of two parameters. It is proved that the existence and uniqueness of the optimal replenishment cycle are compared with the traditional perishable inventory optimization model and the carbon model with the aim of minimum carbon emission. This paper analyzes the influence of carbon trading policy and carbon tax policy on retailers' optimal inventory strategy. The content of this paper is arranged as follows: chapter one introduces the research background of perishable inventory optimization under carbon policy, and reviews the current research situation at home and abroad. The main research results of this paper are introduced. In chapter two, the inventory optimization problem of perishable goods under carbon policy is studied, and the optimal replenishment strategy of retailers is determined under carbon policy. And compared with the traditional perishable inventory model. Through sensitivity analysis, the effects of system parameters on retailer's optimal profit, optimal replenishment period and carbon emissions are studied. This paper studies the inventory optimization of perishable goods under carbon policy when stock is allowed to be out of stock, determines the optimal replenishment strategy of retailers under carbon trading and carbon tax carbon policy, and analyzes and compares the effects of the two policies on the optimal profits and carbon emissions of retailers. Finally, the sensitivity analysis is used to study the influence of the parameters on the retailer's optimal decision.
