【摘要】：自工业革命发生以来,世界各国不断追求经济的高速增长,全球经济飞速发展,取得了傲人的成绩。但近年来,粗放式的经济增长模式所带来的环境问题日渐凸显。二氧化碳等气体的过量排放导致温室效应加剧,引起了全球气候变暖、极端天气频现等一系列严重问题;而在我国,频频出现的雾霾天气使蓝天白云成为一种奢望,呼吸犹如“吸毒”,严重威胁着人们的身体健康。我们从未像今天这般重视环境问题给生活带来的影响,碳减排已逐渐成为国际社会的共识。作为二氧化碳排放大国,我国也在积极承担减排责任,并将宏观层面的国家减排目标分解落实到微观企业层面。转变发展方式、实现节能减排与经济利益的有机结合,开始成为企业寻求发展的新思路。在低碳经济环境下,研究企业如何平衡低碳减排与经济效益的关系,调整生产决策、构建新的供应链契约,不论是从政策层面还是从企业运作层面都具有重要意义。本文主要从两个方面对这些问题进行探讨:第一,研究了两级寄售供应链下的库存决策。建立了一个由单供应商和单零售商组成的两级供应链系统,证明了需求信息的波动会沿着供应链节点向上游逐级扩大;通过对比VMCI(供应商管理寄售库存)和RMCI(零售商管理寄售库存)下的需求信息传递和处理过程,以及两种模式下的库存成本,发现由供应商管理寄售库存要优于零售商管理寄售库存。第二,研究了两级寄售供应链的碳减排及生产优化问题。建立了一个由两个碳减排企业和其下游零售企业组成的两级供应链系统,在随机需求下,将碳减排引入基于收益共享契约的寄售供应链中,建立了VMCI模式下的序贯博弈模型,分别在集中决策和完全分散决策下加以分析,并比较了两种情况下供应链系统的绩效。结果表明,分散决策下的供应链绩效始终低于集中决策,且上游企业的最优减排水平和寄售数量都与分享比例呈负相关,最优的利润分享比例是存在边界的。
[Abstract]:Since the Industrial Revolution, countries all over the world have been pursuing the rapid economic growth, the global economy has developed rapidly, and has made proud achievements. However, in recent years, extensive economic growth model brought environmental problems are increasingly prominent. Excessive emissions of carbon dioxide and other gases have aggravated Greenhouse Effect, causing a series of serious problems such as global warming and frequent extreme weather. In China, the frequent occurrence of haze weather makes blue sky and white clouds a luxury. Breathing is like taking drugs, which is a serious threat to people's health. We have never paid so much attention to the impact of environmental problems on our lives, and carbon emission reduction has gradually become the consensus of the international community. As a big carbon dioxide emitter, China is also taking the responsibility of reducing carbon dioxide emissions, and decomposing the national emission reduction target at the macro level to the micro enterprise level. To change the development mode and realize the organic combination of energy saving and emission reduction and economic benefits has become a new way for enterprises to seek development. Under the low carbon economy environment, it is of great significance to study how to balance the relationship between low carbon emission reduction and economic benefits, to adjust production decisions, and to construct a new supply chain contract, both from the policy level and from the enterprise operation level. This paper mainly discusses these problems from two aspects: first, the inventory decision of the two-level consignment supply chain is studied. A two-level supply chain system consisting of a single supplier and a single retailer is established. It is proved that the fluctuation of the demand information will expand step by step from the supply chain node to the upstream. By comparing the demand information transmission and processing process between VMCI (VMCI) and RMCI (retailer managed consignment inventory), and the inventory cost under the two modes, VMCI (vendor managed consignment inventory) and RMCI (retailer managed consignment inventory), It is found that vendor managed consignment inventory is better than retailer managed consignment inventory. Secondly, the carbon emission reduction and production optimization of two-level consignment supply chain are studied. A two-level supply chain system consisting of two carbon abatement enterprises and their downstream retail enterprises is established. Under random demand, carbon emission reduction is introduced into the consignment supply chain based on revenue-sharing contract, and a sequential game model based on VMCI model is established. The performance of supply chain system is analyzed under centralized decision and completely decentralized decision, and the performance of supply chain system is compared. The results show that the performance of supply chain under decentralized decision is always lower than that of centralized decision, and the optimal emission reduction level and consignment quantity of upstream enterprises are negatively correlated with the share ratio, and the optimal profit sharing ratio has a boundary.
