利用合作博弈分析的理论和方法, 研究了Shapley值作为供应链合作成员收益分配机制的有效性,在此基础上利用Myerson值对不同供应链结构情况下的供应链成员的获利能力做出进一步分析.研究结果表明, 企业在进行供应链合作时,其自身的获利能力不仅取决于它对供应链利润的贡献,还取决于企业自身所在供应链的结构形式及其在供应链中所处的位置. 相似文献

根据对现有文献和Shapley值法基本原理的分析,结合算例,指出了Shapley值法在运用过程中存在忽视风险偏好、适用环境模糊、收益标准单一、分配权重欠合理和实际操作困难等5个方面的问题,提出了解决的对策和措施。对进一步运用Shapley值法对合作收益进行分配具有一定的参考意义。 相似文献

实施VMI后如何分配利益直接关系到各参与者的积极性及VMI的实施效果,学术界长期立足于供应链下游段对此问题进行探讨.选取上游段VMI为研究对象,考虑实施VMI前后供应链参数的变化情况,建立经济效果模型,基于利益分享契约视角,利用Shapley值法构建上游段VMI的利益分配机制,并进行算例分析.结果表明:该机制使得由于实施上游段VMI而产生的利益在各参与者之间合理的分配,解决了供应商由于承担过多库存成本而利益受损的问题,实现了共赢.在实际操作中,该机制可通过各参与者在实施上游段VMI前共同制定利益分享契约而实现. 相似文献

The paper addresses a supply network design problem in which a set of enterprises decides to organise itself as a multi-stage supply network by resource sharing and production coordination. A biform game theory formulation of the problem is obtained by combining the cooperative sub-game in the manufacturing network with the strategic sub-game of the Stackelberg type between the retailer and the manufacturers’ network. As a result of the interaction between these two sub-games, a new type of cooperative game, the quadratic production game, is formulated to describe the supply network design problem under anticipated price elastic demands from the market. The key problem of coalitional stability is addressed through the properties of rationality and fairness of the profit sharing agreement. We prove that the game is non-convex in general and thus, the fair solution given by the Shapley value allocation is not always rational. It is proposed to reinforce the coalition stability by selecting a minimal set of partner enterprises achieving the maximal expected profit and applying a profit sharing policy with guaranteed fairness restricted to the member enterprises. 相似文献

为了研究碳限额及交易下考虑低碳补贴和零售商低碳宣传的双渠道供应链联合减排策略问题,构建由一个制造商和一个零售商组成双渠道供应链,分别建立碳减排补贴与低碳宣传的双渠道供应链集中式决策模型以及无碳减排补贴且无低碳宣传成本分摊、有碳减排补贴但无低碳宣传成本分摊、碳减排补贴且低碳宣传成本分摊的双渠道供应链分散式决策模型,分析其最优决策,并指出政府碳减排补贴、碳减排成本和低碳宣传成本分摊能够实现双渠道供应链协调。研究结果表明,在碳限额及交易下,最优碳减排率、最优低碳宣传水平和双渠道供应链利润与政府补贴比例、低碳偏好对需求的影响系数、低碳宣传对线上消费者需求的影响系数、低碳宣传对线下消费者需求的影响系数都成正向变化关系;最优碳减排率、最优低碳宣传水平和双渠道供应链利润与低碳宣传成本系数、最优碳减排成本系数成反向变化关系;最优碳减排率与碳排放交易价格成正向变化关系,而最优低碳宣传水平、双渠道供应链利润与碳排放交易价格成反向变化关系。 相似文献

We study coordination of assembly systems with random supplier yields and random customer demand. We propose four contracts which are combinations of well-known contracts in the literature and show that the contracts can coordinate the chain under forced compliance. Our contracts have less payment schemes than the existing contracts given for coordination of assembly systems in the literature. We show that arbitrary profit allocation between the levels of the supply chain (the manufacturer or the suppliers) is possible. We also provide sufficient conditions which enable arbitrary profit allocation among the suppliers and illustrate the profit allocation with numerical examples. 相似文献

Studies about supply chain coordination have emphasised maximising the profit of the overall supply chain, but the profit changes of individual members in the supply chain have often been overlooked. It has been shown that profit increment of the whole supply chain may not be beneficial for every individual member. Therefore, the use of quantity discounts to achieve the coordination of a supply chain is discussed in this article. A two-echelon selling system with a single buyer and multiple suppliers is considered to enhance profitability for both sides at the same time. An acceptable quantity discount condition for both the buyer and the suppliers to determine an appropriate order quantity allocation to produce more profits in the supply chain is proposed. Furthermore, the profit distribution between the buyer and each supplier is studied. Finally, the results of the numerical application show that the buyer should focus on managing the procurement costs to decrease the acquiring costs, and the suppliers should focus on the fixed costs of management to reduce the production costs in machine operations. 相似文献

This study employs profit-sharing contracts to coordinate dual-channel supply chains and examines the selection of profit-sharing parameters and the allocation of extra system profit gained from coordination. We characterise the Pareto-optimal contracts for the two- and three-stage dual-channel supply chains, by developing and maximising system utility function related to risk preferences and negotiating power. Under the optimal profit-sharing parameter in a two-stage supply chain, both members are reluctant to cooperate; however, in a three-stage supply chain, under the optimal two profit-sharing parameters selected by optimising the system utility function, the retailer is always reluctant to cooperate, but the distributor or the supplier may have incentives to deviate from cooperation. In this case, the distributor and the supplier will negotiate again as in a two-stage supply chain so that all three members can benefit from coordination with profit-sharing contracts. Besides acting independently, the distributor, in the process of contract negotiation, may choose to form an alliance with the upstream supplier or the downstream retailer, which means the relationship among the three members involving profit allocation after coordination is quite different from that for a two-stage supply chain and is not necessarily interest-contrary. In the contract negotiation, in any kind of scenario, risk aversion and negotiation power have a significant impact on the selection of optimal profit-sharing parameters and the allocation of extra system profit. One member’s risk aversion or its negotiation power may be advantageous to the other. Mathematical examples are illustrated to clarify the contract negotiation process. 相似文献

为研究供应链成员不同博弈地位下双渠道定价及随机库存问题,分别构建制造商主导、零售商主导及双方同等博弈地位的双渠道供应链博弈模型,考察随机市场需求对定价、库存及利润的影响,分析具有不同博弈地位的供应链策略差异,并通过数值仿真探讨最佳响应策略。结果表明,主导方凭借地位优势拥有更强的价格把控权及库存调配能力,获得更高收益;制造商主导型供应链具有更强的渠道整合能力,供应链的整体利润水平高于零售商主导型;同等博弈地位情形的博弈双方可根据共同市场信息及竞争对手策略更新自身策略,具有较低的库存风险,渠道定价越低,但双重边际效应降低了双方收益;市场需求波动越大,渠道定价、库存量及供应链利润均越大,此时主导方利润增幅大于追随者。 相似文献

This paper develops a multi-commodity multi-period optimisation model to analyse market demand disruption risk in agribusiness supply chains. It investigates the role of allocation flexibility and the effectiveness of multiple risk management strategies for achieving allocation flexibility. A robust optimisation formulation is used to obtain risk-averse solutions for an objective combining expected profit and risk. Numerical results are presented for a real-life case study of Zespri’s kiwifruit supply chain. The results show that allocation flexibility is effective for mitigating market demand disruption risk. Three proposed risk management strategies, namely diversified demand market, backup demand market and flexible rerouting, improve both expected profit and risk measures. While diversified demand market and backup demand market strategies are equally important for all decision-makers, flexible rerouting is especially significant for less risk-averse decision-makers. 相似文献
