Demand for a new product is often highly uncertain. As the developer of a new product, the manufacturer may reduce the uncertainty of the product’s demand through observing progress in his product development process or receiving demand signals directly from customers. This paper first shows that a centralized channel always benefits from improved demand information. Yet, to realize this benefit in a decentralized manufacturer–retailer channel, the manufacturer needs to disclose his private demand information to the retailer. We show that the manufacturer’s incentive to share his improved demand information depends on the supply contract signed with the retailer. Furthermore, mandating the manufacturer to disclose his improved demand information can actually reduce the total channel profit. We provide managerial insights by analyzing three widely used contract forms. We investigate whether these contracts are robust under an unanticipated demand information update observed by the manufacturer. We show that the quantity flexibility contract with a high return rate is not robust. The buyback contract, however, is robust and always achieves information sharing while preserving channel performance. 相似文献

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。 相似文献

This paper studies the problem of how to effectively provide product service system (PSS) in a service-oriented manufacturing supply chain under asymmetric private demand information. The PSS in the supply chain is operated heterogeneously and complementarily, in which the manufacturer provides the product while the retailer who possesses private demand information is responsible for adding the necessary value-added service on the basic product. We address the issue of how different contracts affect the decisions and profitability of the supply chain members. Three types of contracts are developed to help supply chain partners to make decisions and enhance the supply chain’s efficiency. The first is the franchise fee (FF) contract, under which the manufacturer provides a two-part tariff contract (wholesale price and franchise fee) to influence the retailer’s decision and to detect her private demand information. The second is the franchise fee with service requirement (FFS) contract, under which the manufacturer specifies the service level required in addition to the two-part tariff contract terms. The third is the franchise fee with centralized service requirement (FFCS) contract, which is similar to the FFS contract but that the service level specified by the manufacturer is the system optimal solution. Our analytical results show that all three contracts enable the manufacturer to detect the retailer’s private demand information, with the FFCS contract achieving the greatest channel profit. Finally, numerical examples are presented, and sensitivity analysis of service level and profit are conducted to compare the performance of the three contracts under different settings. The paper provides managerial guidelines for the manufacturer in contract offering under different conditions. 相似文献

We study cooperative cost reduction in a decentralized supply chain with a single manufacturer and multiple suppliers. The manufacturer assembles components that are procured from the suppliers to produce a final product. Both the manufacturer and the suppliers invest in reducing the unit production costs of the components. We see that neither of the two well-known conventional contracts, the wholesale price contract and the cost-plus pricing contract, generally coordinates the supply chain, i.e., under both of these types of contract, the individual optimal cost-reduction efforts of players deviate from the centralized system-optimal solution. However, this result is not surprising because these contracts encourage either only the manufacturer or only the suppliers alone to invest in cost reduction. 相似文献

Many firms often face quality problems, even though quality improvement has long been a competitive imperative for performance enhancement. When suppliers are the sources of quality problems, prior literature has focused on sustaining a buyer’s competitiveness given the suppliers’ quality uncertainty. Surprisingly, the literature has not paid sufficient attention to quality uncertainty from a coordination perspective. On the other hand, the literature on channel coordination has not considered quality uncertainty in designing a contract of alliance. We bridge the gap between these two streams of literature by explicitly considering quality uncertainty in a coordination framework. In contrast to the coordination literature, we show that channel integration may result in smaller order quantity and less accurate inspection than in a decentralized supply chain if product quality is uncertain. We examine the two most extensively discussed contracts for coordination, buybacks and revenue-sharing, in the presence of quality uncertainty, and find that these two contracts fail to coordinate the supply chain. We then propose a new scheme, the quality-compensation contract, in which the manufacturer compensates the retailer for defective products that are inadvertently sold to consumers, and analytically show that the contract fully coordinates the supply chain. 相似文献

在制造商存在规模不经济环境下,分别针对集中决策模式和分散决策模式,建立了基于一致定价和促销努力的双渠道供应链协调策略模型,分析了规模不经济和服务负溢出效应对供应链运营决策的影响,得到了集中和分散决策下各企业最优运作策略和收益。研究指出,规模不经济的双渠道供应链在分散决策批发价契约下无法实现供应链协调;而分散决策网络渠道收益共享契约能够实现双渠道总收益等于集中决策模式下供应链收益,但无法保证各主体始终获得高于批发价合同下的收益;进一步,设计了带有固定补偿的网络渠道收益共享契约,通过对固定补偿值的有效设计,不仅可以保证双渠道总收益等于集中决策模式下供应链收益,且可以始终保证各主体收益不低于分散决策批发价契约下其所得收益,从而实现各主体利益双赢以及供应链的有效协调。 相似文献

Carbon emission abatement is a hot topic in environmental sustainability and cap-and-trade regulation is regarded as an effective way to reduce the carbon emission. According to the real industrial practices, sustainable product implies that its production processes facilitate to reduce the carbon emission and has a positive response in market demand. In this paper, we study the sustainability investment on sustainable product with emission regulation consideration for decentralized and centralized supply chains. We first examine the order quantity of the retailer and sustainability investment of the manufacturer for the decentralized supply chain with one retailer and one manufacturer. After that, we extend our study to the centralized case where we determine the production quantity and sustainability investment for the whole supply chain. We derive the optimal order quantity (or production quantity) and sustainability investment, and find that the sustainability investment efficiency has a significant impact on the optimal solutions. Further, we conduct numerical studies and find surprisingly that the order quantity may be increasing in the wholesale price due to the effects of the sustainability and emission consideration. Moreover, we investigate the achievability of supply chain coordination by various contracts, and find that only revenue sharing contract can coordinate the supply chain whereas the buyback contract and two-part tariff contract cannot. Important insights and managerial implications are discussed. 相似文献

We analyze a supply chain consisting of one manufacturer and one retailer under consignment sales with a revenue sharing contract. The manufacturer produces before, but charges price to sell the products through the retailer after the demand curve is revealed. The retailer deducts a fraction from the selling price for each unit sold and remits the balance to manufacturer. We refer to the capability whereby firms delay price decision and make sales in response to actual market condition as postponement. We find that, when market demand admits a multiplicative structure, the revenue share and allocation of channel profit between the firms when they have postponement capability are similar to when they do not have such capability. Postponement improves the profits of individual firms. Such an effect is more phenomenal in the centralized system than in decentralized system, and when the market demand is more sensitive to price changes. However, it causes the profit loss, defined as the percentage deviation of channel profit in the decentralized system relative to the centralized system, to worsen, and the gap widens with retailer’s sales cost. When the demand has an additive structure, while the roles of postponement on firms’ decisions differ slightly from those under the multiplicative structure, the structure of the strategic interactions between firms and relative channel performance are not significantly altered. 相似文献

针对两条分别由单生产商单零售商组成的替代产品供应链,假定两种产品的随机总需求依赖于总货架展示量、而每种产品的市场份额与其货架展示量成正比,利用均衡分析方法研究两条供应链在货架展示量与订货量方面的竞争均衡,分别建立了对应两条供应链均为分散式供应链、均为集中式供应链、一条为分散式供应链一条为集中式供应链的EPEC、MPEC和Nash均衡模型。随后分析了供应链竞争下的链内协调合同设计问题,给出了同时协调零售商的货架展示量和订货决策的回购加线性补贴合同和收益共享加线性补贴合同。最后的算例表明,协调是供应链竞争下的占优策略,但两条供应链均协调时的利润反而低于均不协调时的利润,即存在囚徒困境现象。 相似文献

The aim of this paper is to coordinate the inventory policies in a decentralized supply chain with stochastic demand by means of contracts. The system considered is a decentralized two-stage supply chain consisting of multiple independent suppliers and a manufacturer with limited production capacities. The suppliers operate on a make-to-stock basis and apply base stock policy to manage their inventories. On the other hand, the manufacturer employs a make-to-order strategy. Under the necessary assumptions, each supplier is modeled as an M/M/1 make-to-stock queue; and the manufacturer is modeled as a GI/M/1 queue after deriving an approximate distribution for the interarrival times of the manufacturer. Once the supply chain is modeled as a queuing system, centralized and decentralized models are developed. Comparison of the optimal solutions to these models reveals that the supply chain needs coordination. Three different transfer payment contracts are examined in this paper. These are the backorder and holding cost subsidy contracts, the transfer payment contract based on Pareto improvement, and the cost sharing contract. Each contract is evaluated according to its coordination ability and whether it is Pareto improving or not. The results indicate that all three contracts can coordinate the supply chain. However, when the Pareto improvement is taken into account, the cost sharing contract seems to be the one that will be preferred by all parties. 相似文献
