为研究供应链上下游企业间面临碳信息不对称风险时的最优谎报决策,运用Stackelberg博弈理论探讨制造商为主导的二级供应链博弈行为。结合碳排放交易机制下的新型利润模型,采用逆向求解法求解供应链参与者最优决策,并定性分析制造商和零售商的谎报行为以及谎报行为对供应链绩效的影响。研究表明,碳信息谎报与成本信息不对称情形具有明显差异。制造商不论是否谎报碳信息均能最大化自身利润,而零售商将低报碳排量信息。相比零售商不谎报情形,谎报反而能提高制造商与零售商利润,但此时供应链总利润仍低于供应链最优利润。制造商可通过收益共享契约协调供应链,且最优收益共享系数与谎报情形下零售商利润正相关。 相似文献

在电子商务环境下,研究了由两个制造商与一个零售商组成的双渠道供应链中制造商服务努力与广告费用分担,零售商进行广告促销的微分博弈模型,分别在制造商竞争与合作两种情况下得到并比较了各方最优均衡策略与利润。研究发现制造商服务努力和广告费用分担随着竞争的加剧而提高,但当零售商的边际利润较大时,将不会进行费用分担。分析了服务竞争、广告竞争和传统渠道需求所占份额对各方利润的影响,另外发现在合作模型下制造商利润之和增大,当服务效率差异程度在一定范围时,制造商会同时有合作意愿,并使得服务水平、广告投入及零售商利润降低。 相似文献

基于消费者效用理论,分析了制造商与零售商采用Bertrand和Stackelberg 2种博弈策略下,产品的网络渠道相容性特征和零售商创新投入对供应链各方定价和利润的影响,及供应链整体利润的变化情况。研究结果表明,虽然制造商开通双渠道扩大了市场需求,零售商与供应链整体的利润均下降,制造商维持双渠道面临困难。制造商通过设定合理的批发价,将提高供应链整体的利润。另外制造商在设定批发价后采用Bertrand博弈,并鼓励零售商采取供应链最优创新投入力度,将进一步提高供应链整体利润,最后提出了制造商合作策略。这些为制造商基于产品网络渠道相容性选择双渠道,及供应链合作方式与策略提供了依据。 相似文献

在制造商进行生产减排的低碳供应链中,零售商之间存在促销竞争以及促销成本系数为零售商私有信息的情况。分别构建了考虑零售商竞争的低碳供应链集中决策模型和信息不对称决策模型,对制造商减排率以及零售商促销水平进行求解,并通过引入由批发价和成本共担组成的联合契约对供应链进行协调。研究发现:联合契约的引入可以激励零售商在保证自身利益的前提下选择与制造商共享私有信息,不对称信息造成的利润损失得以挽回;随着零售商之间竞争程度的增加,集中决策和信息不对称情形下的供应链利润差减小,用以揭示私有信息的联合契约越有效;制造商减排成本系数的提高降低了供应链成员的利润;零售商促销成本系数越高,制造商在揭示私有信息过程中付出的信息租金越少,对制造商越有利。 相似文献

Offline showrooms develop rapidly to resolve consumers’ uncertainty about whether products fit their needs when they purchase online. This paper considers a supply chain where an offline showroom provides experience service for an existing online retailer and intends to introduce a new competing online retailer to satisfy consumers’ heterogeneous demand. The offline showroom has better knowledge of demand information due to closer to offline consumers. We examine the impact of competition and the offline showroom's optimal channel cooperation strategy under asymmetric information and analyse the equilibrium results under the optimal strategy to shed light on channel cooperation and information strategy for supply chain members. We find that under asymmetric information competition prompts the offline showroom to conceal information which generates signal cost (negative information effect) and to increase experience service level which creates value (positive service effect). The optimal channel cooperation strategy depends on the trade-off between these effects. We also find that competition increases the existing online retailer's profit in some conditions. Besides, in some conditions information asymmetry harms all supply chain members, which suggests the offline showroom to share information with the online retailers; in some conditions, information asymmetry harms the offline showroom but benefits the online retailers. 相似文献

将生鲜农产品供应链中生产商的公平偏好纳入研究视角,在考虑生鲜农产品的有效供给和变质随机性的基础上,通过构建博弈模型,分析了生产商的公平偏好对生鲜农产品供应链的运作产生的影响,并设计了基于;风险分担+收益共享;的协调机制。研究表明,在分散决策下,生产商的公平感知系数和不公平规避系数的不同取值会对生鲜农产品供应链的运作产生不同的影响,且生鲜农产品供应链的最优决策和利润对公平偏好的敏感程度与相应的非易腐品供应链不同;在契约参数满足一定的条件下,所设计的协调机制不仅能够实现生鲜农产品供应链的完美共赢协调,还能够消除生产商的公平偏好。 相似文献

This paper studies how to effectively provide product service system (PSS) in the supply chain with asymmetric information for service-oriented manufacturing (SOM). With a PSS, the manufacturer chooses the product quality, and the retailer, who possesses private cost information, is responsible for adding necessary value-added service based on the basic product. The analytical underpinnings of our work are provided by the principal-agent paradigm. In the paper, we develop three types of contracts and conduct a detailed comparison among the three contract models. With these studies, we find that: (i) the wholesale price contract is dominated by the other two contracts, (ii) The retail price maintenance contract can always generate a higher profit for the manufacturer and a higher welfare for the consumers, whereas the franchise fee (FF) contract can always generate a higher profit for the retailer and (iii) The FF contract can always stimulate more service from the retailer. Our theoretical and numerical results show that there are significantly different effects when the three types of contracts are utilized in the supply chain for SOM with asymmetric information, and which of them is the most attractive will depend largely on the power structure of the supply chain and/or their cost information types. 相似文献

Under the background of “Internet plus” rapid development, the agricultural logistics industry should apply information technology to every link of the agricultural product logistics industry chain. By making full use of the decision making module of the agricultural logistics information system, we can realize the full sharing of information and data resources, which makes the decision-making scheme of the agricultural logistics information system more optimized. In real economic society, the uncertainty and mismatch between the customer’s logistics service demand and the logistics service capability that the logistics service function provider can provide, that is, when the two information are asymmetric, how to use the third-party contract to coordinate the income and profit distribution of the two, to make the information system decision making more reasonable? This paper mainly studies the coordination scheme of agricultural logistics information system decision making under uncertain output and demand information by introducing the spot market. A joint coordination strategy based on revenue sharing and penalty feedback contracts proposes decentralized decision making based on game theory. Experiments show that the flexible ordering strategy proposed in this paper can reduce the logistics service supply chain’s uncertainty and significantly improve the logistics service supply chain’s overall income level through coordination contracts. 相似文献

线下体验服务和保鲜努力投入是影响生鲜电商供应链绩效水平的关键因素。同时考虑线下体验服务和保鲜努力水平,构建生鲜电商供应链决策模型,对集中决策和分散决策下供应链绩效进行比较,在此基础上,设计“双向成本分摊”和“双向成本分摊+收益共享”契约,并验证契约协调的可行性。通过数值仿真,对供应链协调前后最优决策变化以及参数灵敏度影响进行分析。研究发现:1)集中决策、分散决策最优解均与体验服务敏感系数、新鲜度敏感系数呈正相关关系,且集中决策最优解优于分散决策;2)“双向成本分摊”契约可使得体验服务和保鲜努力均达到集中决策水平,但供应链总利润未得到改善;“双向成本分摊+收益共享”契约实现了供应链完美协调,各主体利润均得到帕累托改善。 相似文献

针对一个具有差异化物流服务的供应链,设计了基于数量折扣合同的协调策略以优化供应链定价决策,提高供应链及链上各方企业的利润。首先基于效用函数分析了消费者选择行为,并由此获得每种配送服务的需求函数。然后基于Stackelberg博弈模型求解了分散决策下的供应链均衡策略并与集中决策情形进行对比,发现分散决策下过高的产品销售定价及过低的快速配送附加运费导致消费者效用减少并使供应链总利润降低25%。为了达到集中决策下的最优绩效,基于物流企业视角提出数量折扣定价合同并对相关参数进行设计,发现促使供应链达到协调的数量折扣合同有无数多个,且在一定范围内这些合同能够实现双方企业利润的改善。最后基于数值分析模拟了部分数量折扣合同,并分析了零售企业还价能力对双方利润的影响。 相似文献
