Revenue-sharing versus wholesale price mechanisms under different channel power structures

We consider a supply chain channel with two manufacturers and one retailer. Each manufacturer can choose either a wholesale price contract or a revenue-sharing contract with the retailer. We discuss and compare the results of two different types of contracts under different channel power structures, to check whether it is beneficial for manufacturers to use revenue-sharing contracts under different scenarios. Then we consider a supply chain channel with one manufacturer and two retailers. Each retailer can choose either a wholesale price contract or a revenue-sharing contract with the manufacturer. We analyze the likely outcomes under different scenarios to discover whether it is beneficial to use revenue-sharing contracts.     

Preferences for contractual forms in supply chains

The supply chain contracting literature has focused on incentive contracts designed to align supply chain members’ individual interests. A key finding of this literature is that members’ preferences for contractual forms are often at odds: the upstream supplier prefers relatively complex contracts that can coordinate the supply chain; however, the downstream retailer prefers a wholesale price-only contract because it leaves more surplus (than does a coordinating contract), which the retailer can capture. This paper addresses the following question: Under what circumstances do suppliers and retailers prefer the same contractual form? We study supply chain members’ preferences for contractual forms under three different competitive settings in which multiple supply chains compete to sell substitutable products in the same market. Our analysis suggests that both upstream and downstream sides of the supply chain may prefer the same “quantity discount” contract, which would eliminate the conflicts of interest that otherwise typify contracting situations. More interesting still is that both sides may also prefer the wholesale price-only contract; this finding provides a theoretical explanation for why that inefficient (but simple) contract is widely adopted in supply chain transactions.     

Call,put and bidirectional option contracts in agricultural supply chains with sales effort

This paper develops option contracts in a supplier-retailer agricultural supply chain where the market demand depends on sales effort. First, we examine a benchmark case of integrated supply chain with the loss rate. Second, we introduce three coordinating option contracts led by the supplier to reduce the retailer's risk, where the call option contract can reduce the shortage risk, the put option contract can reduce the inventory risk and the bidirectional option contract can reduce the bilateral risk. We find that both the optimal initial order quantity and the optimal option quantity increase with the sales effort and the option price will balance the influence of the loss rate on supply chain coordination. Furthermore, the bidirectional option price is the highest while its option quantity is the least, and the put option initial order quantity is the highest. Third, we also consider an option contract led by the retailer to reduce the supplier's wholesale risk. Among the above four option contracts, we find that the option quantity led by the retailer is the highest. Finally, the numerical examples present the impact of the parameters on the optimal decisions, and provide practical managerial insights to reduce the different risk in the agricultural supply chain.     

Contracting with demand uncertainty under supply chain competition

We examine supply chain contracts for two competing supply chains selling a substitutable product, each consisting of one manufacturer and one retailer. Both manufacturers are Stackelberg leaders and the retailers are followers. Manufacturers in two competing supply chains may choose different contracts, either a wholesale price contract in which the retailer??s demand forecasting information is not shared, or a revenue-sharing contract in which the retailer??s demand forecasting information is shared. Under supply chain competition and demand uncertainty, we identify which contract is more advantageous for each supply chain, and under what circumstances.     

Contract type and decision right of sales promotion in supply chain management with a capital constrained retailer

From the practices of Chinese consumer electronics market, we find there are two key issues in supply chain management: The first issue is the contract type of either wholesale price contracts or consignment contracts with revenue sharing, and the second issue is the decision right of sales promotion (such as advertising, on-site shopping assistance, rebates, and post-sales service) owned by either manufacturers or retailers. We model a supply chain with one manufacturer and one retailer who has limited capital and faces deterministic demand depending on retail price and sales promotion. The two issues interact with each other. We show that only the combination (called as chain business mode) of a consignment contract with the manufacturer’s right of sales promotion or a wholesale price contract with the retailer’s right of sales promotion is better for both members. Moreover, the latter chain business mode is realized only when the retailer has more power in the chain and has enough capital, otherwise the former one is realized. But which one is preferred by customers? We find that the former is preferred by customers who mainly enjoy low price, while the latter is preferred by those who enjoy high sales promotion level.     

销售商出售看跌期权的供应链优化研究

在由一个供应商和一个销售商组成的单期两级供应链中,处于主导地位的销售商以其卖场所具有的销售能力参与供应链合作,并从销售的每一个产品中获取既定收益。同时,销售商还向供应商出售建立在产品销售量保障基础上的看跌期权,以激励供应商参与供应链合作。论文对上述情形的销售商出售看跌期权的供应链合作问题进行了研究,通过建模与优化分析,证明了在销售商提供看跌期权的供应链合作中,供应商存在唯一的最优生产批量和看跌期权采购量,以及销售商存在最优的从每一单位产品销售中获取的既定收益。论文还揭示了销售商提供看跌期权,虽然无法实现供应链协调,但可以实现供应链参与企业所获得的收益与其所承担的风险相匹配。最后,论文论证了在销售商出售看跌期权机制下,供应链存在收益损失较小的理想合作区域。     

基于公平关切的双渠道低碳供应链博弈分析

价格和服务双因素影响的供应链协调决策模型研究

以单个制造商和存在竞争的两个零售商组成的供应链结构模型为研究对象,建立价格和服务两个重要因素影响的市场需求函数,研究供应链协调决策模型。以销售价格、服务质量和制造商批发价格作为三个决策变量,分析集中决策和分散决策两种情景的最优策略,研究收益共享、服务成本分担、收益共享成本分担等三种不同契约的供应链协调问题,并使用数值仿真方法,分析了相关参数变化对系统协调的影响。仿真结果表明:收益共享契约和成本分担契约需满足一定条件才能达到供应链协调,但其效果不一定实现帕累托最优;收益共享和成本分担契约可实现供应链协调,但收入共享系数需在合理区间取值;改进的收益共享成本分担契约能够避免共享系数的盲区,更加有效地达到供应链协调,保持供应链良好运行。     

Buyback contracts with price-dependent demands: Effects of demand uncertainty

We explore buyback contracts in a supplier–retailer supply chain where the retailer faces a price-dependent downward-sloping demand curve subject to uncertainty. Differentiated from the existing literature, this work focuses on analytically examining how the uncertainty level embedded in market demand affects the applicability of buyback contracts in supply chain management. To this end, we seek to characterize the buyback model in terms of only the demand uncertainty level (DUL). With this new research perspective, we have obtained some interesting new findings for buyback. For example, we find that (1) even though the supply chain’s efficiency will change over the DUL with a wholesale price-only contract, it will be maintained constantly at that of the corresponding deterministic demand setting with buyback, regardless of the DUL; (2) in the practice of buyback, the buyback issuer should adjust only the buyback price in reaction to different DULs while leave the wholesale price unchanged as that in the corresponding deterministic demand setting; (3) only in the demand setting with an intermediate level of the uncertainty (which is identified quantitatively in Theorem 5), buyback provision is beneficial simultaneously for the supplier, the retailer, and the supply chain system, while this is not the case in the other demand settings. This work reveals that DUL can be a critical factor affecting the applicability of supply chain contracts.

零售商主导型供应链渠道管理与悖论机制分析

普遍认为零售企业压榨供应商、但实际上供应商利润率远高于零售商是业界关注的一个热点商业悖论问题。通过构建无退货、一般退货、全额退货、线性回扣等体现零售商不同强势地位的供应链渠道管理模型,研究并比较了退货和回扣等强势契约机制以及销售努力对零售供应链管理绩效的影响。分析表明供应商通过批发价定价可以有效转移强势契约带来的风险和成本支付,零售商不能通过强势契约显著提升零售供应链效益。零售商应该利用渠道优势首先强化对批发价定价权的影响,在此基础上合理采用强势契约机制。本文研究很好地解释了零供双方渠道地位与利润水平矛盾的商业悖论问题。     

强制减排规制下基于碳减排利润增量分享契约的供应链协调研究

碳减排会增加制造商的成本,导致批发价和零售价提高,从而抑制市场需求。以此为背景,本文针对由一个制造商和一个零售商组成的供应链,研究了强制减排规制下考虑消费者低碳偏好时的供应链决策与协调。通过设计碳减排利润增量分享契约协调制造商和零售商的决策,实现帕累托改进,利用Rubinstein讨价还价模型最终确定减排利润分享比例。研究发现,实施碳减排利润分享契约能有效提高零售商的订货量,并降低批发价格;制造商的利润随着消费者低碳意识提高而提高;当净化率较低时,零售商的利润随消费者低碳意识提高而提高;当净化率较高时,零售商的利润随消费者低碳意识提高而降低;最后,论文通过数值模拟验证了碳减排利润分享契约的有效性。     

Pareto-optimal contracts for a supply chain with satisficing objectives

We analyse a decentralized supply chain consisting of a supplier and a retailer, each with a satisficing objective, that is, to maximize the probability of achieving a predetermined target profit. The supply chain is examined under two types of commonly used contracts: linear tariff contracts (including wholesale price contracts as special cases) and buy-back contracts. First, we identify the Pareto-optimal contract(s) for each contractual form. In particular, it is shown that there is a unique wholesale price that is Pareto optimal for both contractual types. Second, we evaluate the performance of the Pareto-optimal contracts. In contrast to the well-known results for a supply chain with the traditional expected profit objectives, we show that wholesale price contracts can coordinate the supply chain whereas buy-back contracts cannot. This provides an additional justification for the popularity of wholesale price contracts besides their simplicities and lower administration costs.     

销售努力及双市场化期权下的三级供应链协调

本文针对需求随机且受到零售商销售努力影响的情况,研究了由制造商、分销商和零售商组成的三级供应链的协调问题。文章首先用双期权契约对三级供应链进行协调,即在制造商和分销商以及分销商和零售商之间都采用期权契约,发现在零售商独自承担努力成本的情况下仅通过双期权契约无法协调供应链。因此在双期权契约的基础上加入了努力成本共担契约,发现当期权价格满足某种线性关系以及零售商努力成本按特定比例分摊时,联合双期权契约和努力成本共担契约能顺利协调供应链。在此基础上,文章还引入了期权的市场化定价规则,研究了期权采用市场化定价规则对供应链协调产生的影响,研究表明,引入期权市场化定价规则增加了供应链协调需要满足的条件,降低了协调的可能性,且协调状态下的期权价格受到市场因素如利率、价格波动率等的影响。最后,文章给出了期权市场化定价规则下供应链协调的条件以及参数变化对协调的影响。     

间接和混合渠道下零售商引入自有品牌的影响分析

自有品牌的引入使渠道中制造商和零售商的市场绩效发生了较大变化。本文构建了两个制造商和一个零售商情境下零售商引入自有品牌的模型,分析了在间接渠道和混合渠道两种条件下引入自有品牌对零售商、制造商市场绩效的影响。通过分析表明,在间接渠道和混合渠道下,零售商引入自有品牌后,一方面会导致制造商品牌的批发价格、零售价格和制造商利润的降低,对制造商不利;另一方面能增加渠道总利润、零售商利润及零售商在整个渠道中的利润分成,零售商应该将自有品牌的战略定位为高质高价的品牌,而非低价低质的原始状态型品牌,而制造商单纯靠改变销售渠道模式的策略并不足以对抗自有品牌的冲击。     

Coordinating a three-stage supply chain with competing manufacturers

It is common for multiple manufacturers to compete in one common market. This paper considers a three-stage supply chain consisting of two competing manufacturers, one distributor, and one retailer. The two manufacturers’ products are substitutable with each other, and both manufacturers sell their products through the common distributor and the common retailer. In this supply chain, three contract mechanisms are discussed. The first one is wholesale-price (WP) contracts. The second one is pairwise revenue-sharing (PRS) contracts indicating that the revenues are shared by all pairs of adjacent entities. The third one is spanning revenue-sharing (SRS) contract indicating that the retailer simultaneously shares his revenues with all supply chain members. First, we discuss the effects of competition between manufacturers on both decentralized and centralized supply chains under the WP contracts. Second, we discuss the coordination mechanisms. The PRS and SRS contracts are used to coordinate the entire supply chain. We present the drawbacks of the PRS contracts in coordinating this competing supply chain and suggest using the SRS contract instead. After an SRS contract is adopted, it is evaluated using the WP contracts as a benchmark. The conditions necessary for an SRS contract to achieve a win–win outcome are then presented. Finally, some numerical examples are provided.     

不同补贴对象下闭环供应链信息共享价值研究

在一个制造商和一个零售商组成的二级闭环供应链中,为研究政府补贴下供应链需求信息共享对决策的影响及共享价值,针对两种补贴对象,构建并求解无信息共享和信息共享博弈模型,并进行仿真验证.研究表明:1)两种补贴对象下,制造商均能从信息共享中获益,零售商仅在绿色成本和回收成本较低时才会从信息共享中获益;绿色成本和回收成本稍高时,设计基于谈判势力的信息补偿机制能有效促进零售商共享信息.2)产品绿色度和回收率随预测需求量的提高而提高,批发价和零售价仅在回收成本较低时,才会随预测需求量的提高而提高.3)在仅补贴一方情况下,当补贴对象为低补贴一方时,两个主体所获的信息共享价值大;若对两者的补贴均较低,两个主体均希望补贴对象为零售商;若对两者的补贴均较高,零售商不愿共享需求信息.     

考虑权力结构的产品服务供应链服务渠道选择及协调研究

在制造业服务化转型过程中,传统的产品供应链转变为了产品服务供应链,为顾客提供产品和服务,服务可以由制造商或零售商提供,权力结构会对服务渠道的选择产生影响。本文通过建立博弈模型,研究了制造商为核心、零售商为核心以及制造商与零售商权力均等三种权力结构下最优服务渠道的选择问题,并应用两部定价契约对最优服务渠道的结果进行协调。研究发现,当制造商为核心时,最优的服务渠道为零售商提供服务,当零售商为核心时,最优的服务渠道为制造商提供服务,当制造商与零售商权力均等时,不存在最优的服务渠道。两部定价契约可以实现最优服务渠道的协调,最后通过数值仿真对结论进行了验证。     

交易流动性不对等环境下基于收入共享契约的供应链协调

供应链中存在单一生产商、单一零售商和一个交易流动性不对等的第三方B2B电子交易市场。在零售需求不确定的情况下,分别建立了供应链集中决策模型、传统固定合约均衡决策模型、收入共享契约分散决策模型,验证了收入共享契约在多渠道采购环境下仍可以协调供应链,分析了使供应链达到帕累托改进的收入共享契约的参数设定,最后分别从卖出流动性和买入流动性两个角度讨论了交易流动性对供应链的影响。研究结果表明,卖出流动性好的电子交易市场可以促使供应链达到最优生产量,实现整体收益的最大化;两种交易流动性的趋好都会提高供应链效率,但生产商更偏好卖出流动性好的电子交易市场。     

需求扰动下竞争型闭环供应链的生产与协调决策分析

研究了一个制造商和两个竞争型零售商组成的闭环供应链系统在面临需求扰动时的生产决策与协调机制设计问题。研究发现:当需求扰动不大时,产量和回收率决策具有鲁棒性,但销售价格始终随着需求的扰动而变动;当面临较大的需求正扰动时集中决策者、制造商和零售商都愿意改变生产决策,当面临较大的需求负扰动时集中决策者和制造商也愿意改变决策,但零售商更希望保持原有决策;收入共享契约可以协调扰动前后的闭环供应链,但当存在较大的需求负扰动时零售商要求分享更多的利润。
