发布时间:2018-10-12 18:06
【摘要】:随着温室气体排放所引起的环境问题日益严峻,越来越多的企业在追求自身利润最大化的同时将碳减排问题提到了企业发展的战略层面。而面对复杂多变的市场环境,企业间的竞争也逐渐转变为供应链之间的竞争,供应链中成员企业间在选择合作策略时应将环境效益和经济目标结合考虑,如此才能在实现供应链经济目标的同时降低整体的碳排放,从而使整个供应链达到碳优化状态。对供应链成员企业合作博弈的整体利润,设计协调机制对其进行合理的分配是维持供应链稳定发展的前提。本文研究了包含单个供应商、单个制造商和多个零售商的三级供应链,考虑了碳减排率和供应链终端产品价格两个因素,探讨了供应链中成员企业选择何种合作博弈策略能够在提高整体利润的同时优化自身收益并实现供应链碳优化。本文的主要工作如下:(1)模型构建。在碳优化理论研究的基础上,用碳减排率度量碳优化的概念。在考虑碳减排率和产品价格两个因素下,构建了四种合作博弈策略模型:独立决策策略、基于碳减排率的合作博弈策略、基于供应链终端产品价格的合作博弈策略、基于碳减排率和供应链终端产品价格的两阶段合作博弈策略。并运用逻辑推理的方法对所构建的合作博弈策略模型进行了求解。(2)协调机制。对所构建的四种策略模型的结果进行了比较分析,得到了供应链整体利润最高和成员企业碳减排率最优的合作博弈策略。并设计了两种协调机制(收益共享机制、不对称纳什协商机制)分配供应链整体利润,以确保供应链成员企业在合作博弈策略下获得的利润不低于其它策略下的利润。(3)潜在应用研究。以上海宝山钢铁有限公司不锈钢事业部所在三级供应链为例,验证了四种策略模型的结果,并通过协调机制对合作博弈策略下整体利润进行了分配,设计收益共享机制得到分配系数取值范围,在此基础上通过不对称纳什均衡协商机制得到基于满意度的具体收益分配方案。将环境效益与企业经济目标相结合,通过设计协调机制对合作博弈整体利润进行分配,能够激励供应链成员企业主动参与到合作博弈中,并达到最优的碳减排率,从而实现整个供应链的碳优化,这一前沿性问题的研究对供应链运作更具有实际指导意义。
[Abstract]:With the increasingly serious environmental problems caused by greenhouse gas emissions, more and more enterprises are pursuing their own profit maximization, and the carbon emission reduction problem has been raised to the strategic level of enterprise development. In the face of complex and changeable market environment, competition among enterprises is gradually transformed into competition between supply chains. In the selection of cooperation strategies among member enterprises in the supply chain, environmental benefits and economic objectives should be taken into account. In order to achieve the economic goal of supply chain and reduce the overall carbon emissions, the whole supply chain can reach the state of carbon optimization. For the whole profit of cooperative game of supply chain member enterprises, it is the premise to design coordination mechanism to distribute it reasonably to maintain the steady development of supply chain. In this paper, a three-level supply chain including a single supplier, a single manufacturer and a number of retailers is studied. The carbon emission reduction rate and the price of the end product in the supply chain are taken into account. This paper discusses the cooperative game strategy chosen by the member enterprises in the supply chain which can improve the overall profit and optimize their own income and realize the carbon optimization of the supply chain. The main work of this paper is as follows: (1) Model construction. Based on the research of carbon optimization theory, the concept of carbon optimization is measured by carbon emission reduction rate. Under the consideration of carbon emission reduction rate and product price, four cooperative game strategy models are constructed: independent decision strategy, cooperative game strategy based on carbon emission reduction rate, and cooperative game strategy based on supply chain terminal product price. A two-stage cooperative game strategy based on carbon reduction rate and end product price in supply chain. The cooperative game strategy model is solved by logical reasoning. (2) Coordination mechanism. The results of the four strategy models are compared and analyzed, and the cooperative game strategy of the supply chain with the highest overall profit and the best carbon reduction rate of the member enterprises is obtained. Two coordination mechanisms (revenue sharing mechanism, asymmetric Nash negotiation mechanism) are designed to distribute the overall profits of the supply chain. In order to ensure that the profit of supply chain member enterprises under cooperative game strategy is not lower than that of other strategies. (3) potential application research. Taking the three-level supply chain of stainless steel division of Shanghai Baoshan Iron and Steel Co., Ltd as an example, the results of four kinds of strategy models are verified, and the overall profits under cooperative game strategy are distributed through coordination mechanism. The range of the distribution coefficient is obtained by designing the revenue-sharing mechanism, and the specific income distribution scheme based on satisfaction is obtained through the asymmetric Nash equilibrium negotiation mechanism. Combining environmental benefit with enterprise economic goal and designing coordination mechanism to distribute the overall profit of cooperative game, the supply chain member enterprises can be encouraged to participate in cooperative game actively and achieve the optimal carbon emission reduction rate. In order to realize the carbon optimization of the whole supply chain, the research of this frontier problem has more practical guiding significance for the operation of the supply chain.
