基于货到付款支付模式且考虑银行存贷的二级供应链Stackelberg定价决策

在货到付款支付模式下二级供应链定价决策中,供应链企业资金闲置时向银行存款或资金约束时向银行贷款(银行存贷)的行为是不可忽视的重要因素,如何构建基于货到付款支付模式且考虑银行存贷的二级供应链Stackelberg定价决策模型是需要关注的重要问题。在本文中,首先给出了市场需求函数;然后,基于货到付款支付模式,针对制造商资金或零售商资金约束情形,分别构建针对不同供应链权力结构的定价决策模型;进一步地,通过模型求解确定了不同情形下不同权力结构的制造商与零售商的最优策略,并分析了模型参数对最优策略的影响;最后,针对不同资金约束情形与不同权力结构的最优策略以及银行利率对最优策略及利润影响,给出了对比分析。研究表明三种银行利率均会影响最优策略,且资金约束对象差异的影响明显。     

Decision-Making at Board Level Using Decision Analysis: Two Case Studies

Two cases are described: the first in a newspaper publishing company concerned a strategic pricing decision; the second involved a property litigation problem in a food retailing company. Neither of the decision analysis models presented to the respective Boards of Directors was at all complex mathematically but they were highly influential on the decision-making processes. Indeed both were critical to the decisions made at those times. Some possible lessons are drawn from the cases with respect to these types of decision-making process, the type and complexity of model appropriate and information problems.     

A review of multi-product pricing models

The importance of good pricing strategies in business theory is clearly recognized, as can be seen from the huge volume of pricing research done over the years. What we attempt to do is to provide a general review of multi-product pricing models, focusing primarily on those where demands are explicitly dependent on prices. As the pricing decision may be made jointly with other economic parameters, we will not only review models that focus solely on pricing; we will also discuss models where pricing choices are made jointly with other decisions like production or distribution of resources.     

供应商歧视定价下网络零售商店内推介策略研究

研究了供应商歧视定价时网络零售商店内推介策略。首先,以供应商统一定价模型为基准,通过逆推归纳法求解不同推介策略组合下零售商和供应商的均衡利润,研究发现:仅当消费者对两家零售商认知差异较小时四种推介策略组合才能同时成立,且随着推介费用的增大两零售商均衡推介策略依次为:都不推介、仅强势零售商1推介和双向推介。其次,构建供应商歧视定价模型,发现歧视定价有利于弱势零售商2获得市场空间,随着消费者对两家零售商感知差异和推介费用的变化呈现出多样化的均衡推介策略。最后,探讨了两种定价模型下供应商的最优利润,发现受推介策略的影响歧视定价未必能够为供应商带来更多利润。     

随机需求下考虑零售商竞争的闭环供应链定价与协调

在随机需求环境下考虑两零售商间存在竞争的闭环供应链定价与协调问题, 其中两个零售商各自面临不同的随机市场需求,并且各自的回收量都受到对方回收价格的影响。在集中决策和分散决策两种情形下分析了制造商和两零售商的定价决策问题,并运用收入费用共享契约实现了闭环供应链的协调。     

买方抗衡势力对上游企业定价形式决策的影响——基于讨价还价博弈的分析

基于上游垄断、下游双寡头竞争的纵向市场结构,在讨价还价博弈的框架下,构建了下游零售商均无买方抗衡势力和单个零售商具有买方抗衡势力两种情况下的,上游供应商最优定价形式决策模型,分析了买方抗衡势力对供应商定价形式决策的影响。研究发现:从供应商利润角度来说,当零售商均无买方抗衡势力时,两部收费制和RPM(转售价格维持)是等价的,且都优于线性定价;当单个零售商具有买方抗衡势力时,RPM优于两部收费制,同时也优于线性定价,但是两部收费制与线性定价之间的关系不确定。在此结论之上,本文还讨论了政府对RPM采用不同规制政策时,供应商最优的定价形式选择。     

随机需求下竞争零售商的定价策略研究

本文研究了随机需求下两竞争零售商的定价策略选择(响应性定价或清仓定价)、产品订货量及响应性价格的联合决策问题。通过将问题转化为一个三阶段的博弈模型,基于Kuhn-Tucker条件求解了两零售商不同定价策略子博弈下的均衡产品订货量及响应性定价决策,分析了不同定价策略子博弈下产品订货量及价格决策的差别以及潜在市场需求不确定(期望和方差变动)对订货量和定价策略的影响。数值分析结果表明,当潜在市场需求服从均匀分布时,响应性定价子博弈是帕累托最优策略,清仓定价子博弈是零售商的均衡策略,混合定价子博弈下两零售商的收益差距较大。     

考虑政府约束的再制造闭环供应链差别定价博弈模型

本文考虑政府对废弃产品回收的奖惩约束措施,针对一类由制造商、零售商构成的再制造闭环供应链系统,基于博弈论方法研究了新产品和再制造品存在定价差别时集中决策和分散决策模式下的定价策略,得出了闭环供应链成员的最优定价策略和利润,并分析了政府约束措施对闭环供应链运作的影响。研究表明:集中决策下供应链效率高于Stackelberg博弈分散决策,为此设计了一个收益共享协调定价契约实现了闭环供应链的协调,进而分析了政府回收约束情况下再制造过程利润超过制造过程的再制造优先条件。算例分析验证了定价策略及协调机制的有效性。

Integration of pricing and capacity allocation for perishable products

For years pricing and capacity allocation decisions in most revenue management models have been carried out independently. This article presents a comprehensive model to integrate these two decisions for perishable products. We assume that the supplier sells the same products to different micro-markets at distinct prices. Throughout the sales season, the supplier faces decisions as to which micro-markets or customer classes should be served and at what prices. We show that (i) at any time, a customer class is active (being served) if and only if the price offered is over a threshold level, but the optimal price may not be the highest one of the supplier’s choice; (ii) when the price decision is made in conjunction with inventory, it is similar to the procedure shown in pure pricing models, i.e., the optimal price comes from a subset of prices that forms a maximum increasing concave envelope; (iii) because of dynamic changes in the optimal prices, the nested-price structure does not necessarily hold in general and needs to be redefined; and (iv) the optimal pricing and capacity control policy is based on a sequence of threshold points that incorporate inventory, price and demand intensity. Numerical examples are provided.     

Two-period pricing and decision strategies in a two-echelon supply chain under price-dependent demand

This paper presents a two-period supply chain model which is comprised of one manufacturer and one retailer who are involved in trading a single product. The demand rate in each period is dependent on the selling prices of the current period and the previous period. We assume that the manufacturer acts as the Stackelberg leader and declares wholesale price(s) to the retailer who follows the manufacturer’s decision and sets his selling prices for two consecutive periods. The manufacturer adopts one of the two pricing options: (1) setting the same wholesale price to both the selling periods (2) setting different wholesale prices to two different selling periods. Based on these pricing options, we develop four decision strategies of the manufacturer and the retailer and compare them. For a numerical example, we study the effects of these decision strategies on the optimal results of the supply chain. Further, we graphically analyze under what circumstances a particular decision strategy plays a dominant role.     

不同渠道偏好和运营成本下双渠道闭环供应链定价决策研究

本文以消费者对传统零售渠道和网络直销渠道的不同偏好和不同渠道运营成本为基础,研究零售商销售新产品并回收废旧产品、制造商开辟网络直销渠道的双渠道闭环供应链中成员的定价决策问题。建立三种不同市场权力结构下的定价博弈模型,用逆向归纳法得到模型的最优解,并用解析分析和数值分析得到消费者的渠道偏好程度和渠道运营成本对定价决策和利润的影响。研究表明:最优直销价格随网络直销渠道偏好程度的增加而上升,最优零售价格随网络直销渠道偏好程度的增加而下降;网络直销渠道运营成本增加对零售商有利但不利于制造商;传统渠道运营成本的增加对所有成员都不利。     

基于无套利模型的人民币利率互换定价

基于两种代表性无套利模型——Black-Derman-Toy(BDT)和Hull-White模型,构建考虑单向违约风险的人民币利率互换定价模型。运用这两种定价模型对1年期3MSHIBOR-IRS进行定价,对两种定价模型的定价结果进行敏感性分析。结果表明,两种定价模型表现出定价偏离的一致性,基于BDT模型比基于Hull-White模型的定价结果与报价的差距更小。     

基于市场细分的双渠道供应链决策模型

提出零售商在一级市场生命周期末开辟二级市场的构想。在市场信息完全的前提下,根据消费者效用选择函数建立了双渠道供应链定价决策模型,并求解出零售商开辟二级市场后的零售商和制造商的最优定价。研究发现:分散式决策模式下,当一级市场仅有网络直销渠道,零售商不会开辟二级市场;当一级市场零售渠道和网络直销渠道都有需求,二级市场引入后的供应链成员利润可能实现Pareto改进;集中式决策模式下,只有一级市场零售渠道、网络直销渠道和二级市场都有需求且二级市场接受度超过临界值后,二级市场引入能提升供应链系统绩效。因此,零售商在特定条件下才会开辟二级市场。     

搜寻成本下可替代产品的定价策略与库存决策

为探寻存在搜寻成本情况下消费者购买可替代产品时的定价与库存问题,从消费者效用出发,对厂商收益构建了基于马尔可夫决策过程的优化模型。在消费者方面,分析了其购买与继续搜寻的条件,并分别在搜寻成本不变和搜寻成本边际递减的情况下研究了消费者保留效用的变化情况以及购买相应产品的概率。此外,与很多相关文献不同的是,由于搜寻成本的存在,该情形下的消费者并不一定会在完成购买之前搜寻完所有的产品。在厂商方面,根据实际情况构建不同搜寻顺序下的收益模型并求解出最优定价策略与库存策略,并将定价模型与库存策略扩展到了动态的环境,为厂商制定价格及库存方案提供相应的决策支持。     

两零售商竞争下第三方回收闭环供应链的决策及协调

为研究同时考虑零售商竞争与第三方回收闭环供应链的定价决策及协调问题, 分别建立了集中与分散决策模式下的闭环供应链优化模型, 并提出了基于改进K-S法的协调机制。研究表明:在分散式闭环供应链决策下, 较之两零售商与第三方, 制造商总是可以获得最大的利润。两零售商在产品价格上竞争程度的增强不仅可以有效提高产品销量, 同时对废旧产品的回收也起到了很好地促进作用。闭环供应链成员企业间的合作策略能有效消除系统的“双重边际”效应, 且较之零售商及第三方回收商, 制造商的合作动力更强。     

Pricing policies for complementary products in a dual-channel supply chain

This paper investigates the pricing problem of complementary products in a supply chain with two manufacturers and one retailer, one of the two manufacturers uses dual channels including an online channel and a traditional retail channel to sell its product. We formulate four pricing game models through considering different market power structures of channel members, and derive the corresponding optimal pricing strategies. Based on the theoretical and numerical analysis, we study the effects of consumer channel loyalty, the level of complementarity, and the market power structures on the pricing strategies and the maximal profits of two complementary products. Some interesting and valuable managerial insights are obtained.     

Pricing decisions for substitutable products with a common retailer in fuzzy environments

The pricing problem of substitutable products in a fuzzy supply chain is analyzed by using game theory in this paper. There are two substitutable products produced by two competitive manufacturers respectively and then sold by one common retailer to the consumers. Both the manufacturing cost and the customer demand for each product are characterized as fuzzy variables. How the two manufacturers and the common retailer make their own pricing decisions about wholesale prices and retail prices are explored under four different scenarios, and the corresponding expected value models are developed in this paper. Finally, a numerical example is given to illustrate the effectiveness of the proposed supply chain models.     

Pricing and effort investment for a newsvendor-type product

We investigate a dominant retailer’s optimal joint strategy of pricing and timing of effort investment and analyze how it influences the decision of the manufacturer, the total supply chain profit, and the consumers’ payoff. We consider two pricing schemes of the retailer, namely, dollar markup and percentage markup, and two effort-investment sequences, namely, ex-ante and ex-post. A combination of four cases is analyzed. Our results show that: (1) under the same effort-decision sequence, a percentage-markup pricing scheme leads to higher expected profit for the retailer and the whole supply chain, but a lower expected profit for the manufacturer and a higher retail price for the consumers; (2) under the same markup-pricing strategy, the dominant retailer always prefers to postpone her effort decision until the manufacturer makes a commitment to wholesale price, since it can result in a Pareto-improvement for all the supply chain members. That is, the retailer’s and manufacturer’s expected profits are higher and the consumers pay a lower retail price; and (3) among the four joint strategies, the dominant retailer always prefers the joint strategy of percentage-markup plus ex-post effort decision. However, the dominated manufacturer always prefers the joint strategy of dollar-markup plus ex-post effort decision, which is also beneficial to the end consumers.     

考虑溯源系统应用的优质农产品双渠道供应链决策研究

优质农产品溯源系统的引入,既能提升有效供给、缩短流通时间,又能降低流通中的数量损耗和价值损失,由此带来了双渠道供应链系统在投资、销售、定价等方面的系列决策问题。考虑制造商开辟电子渠道、从溯源系统降低流通损耗和提高质量出发,分别构建制造商主导型的双渠道供应链决策模型。通过对比分析应用前后各成员在投资、定价及销售方面的最优策略,得到相关的核心边界值。数值仿真结果表明:核心边界值主要与双重损耗的改善程度及其他参数相关,各成员及系统接受溯源系统的应用成本不同,应用成本对各渠道销量的影响程度亦不相同,但各成员调整定价的应用成本边界值是一致的。
