【摘要】 随着社会的发展,绿色供应链管理逐渐成为供应链管理的研究热点,利润最大也一直作为管理目标.近来年,与产品等级相关的绿色供应链管理得到学者们的广泛关注.本文研究易腐产品绿色供应链管理问题,包含了由生产供应商1,2和顾客构成的两条并列二级链,生产绿色等级不同的相同产品.由于产品寿命有限,本文在已有产品变质率的基础上,根据是否采取保鲜措施给出了新的产品易腐率定义,并用三参Weibull函数来刻画产品易腐率.在生产供应商的库存水平受需求率,价格敏感和易腐率影响时,建立库存水平变化的微分方程,得到总库存量.结合供应链实际可能产生的各项成本,进行综合考虑得到供应链中对象及整体的利润函数.首先,在政府规定出产品最低绿色等级和补贴等级后,分析了生产供应商产品绿色等级对自身利润产生的影响,给出确定产品最优绿色等级策略,以保证其利润最大;在政府规定出补贴等级和生产供应商确定产品绿色等级后,分析了最低绿色等级改变时对生产供应商们利润产生的影响,为政府对企业开展扶持或打压工作提供一定依据,更好地进行市场调控.其次,分析了易腐率中位置因子对供应链中对象及整体利润产生的具体影响,并进行灵敏度分析.再次,在是否采取保鲜措施两种情况下,分别对比供应链中对象及整体利润,进行是否采取保鲜措施的决策.最后,供应链的总收益即政府总收益,这与顾客绿色环境满意度相关,讨论了该满意度对总收益的影响,给出提高总收益的相关策略;从另一角度说明使供应链单一对象利润最大并不能使供应链整体利润最大.第一章介绍了选题背景;研究现状;文献总结及本文创新点;研究框架.第二章给出新的产品易腐率定义,建立生产供应商库存水平变化的微分方程,综合考虑供应链各项成本,得到生产供应商1,2的利润函数.分析产品绿色等级,最低绿色等级,位置因子等对其总利润产生的影响,并获得最优策略.第三章研究了政府的总收益,分析了顾客绿色环境满意度,绿色环境偏好支付因子,最低绿色等级等对其总收益产生的影响,并获得最优策略.第四章是结论和展望.主要对本文展开的工作进行了总结和展望.更多还原

【Abstract】 With the development of society,green supply chain management has become the research hotspot of supply chain management while the maximum profit has always been the goal.In recent years,green supply chain management related with the product’s green level has attracted the attention of scholars.This paper researches the green supply chain management with perishable products,which contains two parallel secondary chains and the same products with different levels.Based on fresh measures and the deterioration rate,the new definition of perishable rate is given by using the three-parameter Weibull distribution function.Since the supplier’s inventory is influenced by the demand rate,the price sensitivity and the perishable rate,this paper combains the inventory and various costs to get the individual and the whole profit function.Firstly,this paper analyses the influence of the green level on suppliers’ profit after the goverment specifies the level of minimum and subsidy,and then gives the optimal green level to ensure the maximum profit;Similiarly,this paper analyses the influence of the minimum level on suppliers’ profit to help the government control the market preferably.Secondly,this paper analyses the specific effects of position factor on the individual and the whole profit,and then makes sensitivity analyses.Thirdly,the individual profit is compared in situation of the fresh measure is taken or not,the same method is applies to the whole profit.Finally,this paper analyses the influence of the customers’ satisfaction on the government’s revenue to improve the revenue,while the whole profit is the government’s revenue.Besides,this paper explains the problem of maximizing the individual profit is not equal to maximizing the whole profit.Chapter one mainly introduces the background,research situation,literature summary,innovation and framework.Chapter two gives the new definition of perishable rate,obtains the supplyers’ profit and analyses the influence of the green level to have the optimal strategy.Chapter three obtains the government’s revenue,analyses the influence of relevant factors to have the optimal strategy.The conclusion and the prospect is in chapter four.更多还原
