基于供应链系统的主导零售商价格控制研究

零售商主导供应链是在近一二十年内出现的新模式,是基于零售市场以需求为导向的大背景产生的。供应链模式本身是基于链内各企业要结成战略性伙伴关系,协调发展,在价格定价上,交易双方必须向系统定价的标准靠拢,但由于主导零售商对于价格获得了控制权,主导零售商的价格控制,对于供应链系统收益就产生了明显的影响。本文阐述了零售商主导供应链及主导零售商的内涵,并从这两个方面探讨了供应链中的定价控制问题,以及对于供应链系统收益的影响。

公平偏好下供应链批发价格契约协调研究综述

生猪疫情对我国猪肉供应链稳定性的影响

试验旨在研究生猪疫情对我国猪肉供应链稳定性的影响。选取12家生猪上市企业作为样本,运用面板Tobit估计方法分析。结果表明,我国猪肉供应链稳定性整体呈上升态势。细分比较,猪肉供应链上游稳定性强于猪肉供应链下游稳定性。生猪疫情暴发后,仔猪价格、玉米价格与猪肉供应链上游稳定性呈显著负相关,生猪养殖规模化水平与猪肉供应链上游稳定性呈显著正相关;仔猪价格、玉米价格与猪肉供应链下游稳定性呈负相关,鸡肉价格、牛肉价格与猪肉供应链下游稳定性呈正相关。研究表明,在有效控制生猪疫情的前提下,针对猪肉供应链上下游稳定性不同的影响因素,政府与企业应当采取差异化举措。

不同情形下供应链优化决策模型的比较分析

本文提出三种不同情形(制造商与零售商追求各自利润最大化。并且没有价格折扣策略；制造商与零售商共同追求总利润最大化,不实施价格折扣策略；制造商与零售商共同追求总利润最大化,并实施价格折扣策略)下供应链价格和库存补充策略的优化决策模型,并通过具体数例进行比较分析,结果表明,供应链合作并实施价格折扣策略时的供应链总利润最高,而供应链双方利润分配系数的变化对基于供应链总利润最大化的供应链优化决策没有影响．

Optimal pricing and production decisions in a supply chain with e-marketplace

The concept of the e-marketplace is introduced.Considering a supply chain with a single manufacturer who sells a single item in an e-marketplace,an analytical model for the use of the e-marketplace in a supply chain is provided.Assuming the market demand is stochastic and price-dependent,the conditions under which the manufacturer and the e-marketplace owner share the market in equilibrium is developed.The existence and uniqueness of the optimal selling price,quantity and transaction percentage are proved.An integrated supply chain is put forward,and then the efficiency of supply chain coordination is studied by comparing the integrated supply chain with the decentralized supply chain.To gain further insights on the theoretical models,extensive simulations are then carried out.

基于博弈论的制造商定价协调研究

针对拥有网上直销渠道的制造商与同时拥有传统零售渠道和电子商务渠道的零售商组成的多渠道供应链,考虑渠道需求和促销投入的影响,建立了制造商主导的Stackelberg博弈模型,研究了供应链成员的定价与均衡策略,并分析了需求函数的影响因子对供应链成员价格选择的影响。研究表明,零售渠道的市场需求占市场总需求的分流比例与促销投入两个影响因子对供应链成员的定价策略都有显著的相关性。最后设计促销补贴契约,给出了零售商进行最优促销投入的前提下,制造商应做出的最优促销补贴率。

Coordinating pricing strategies in supply chain under asymmetric information and disruptions

The coordinating pricing strategies with asymmetric cost information under disruptions are investigated in a one-supplier-one-retailer supply chain system.While the retailer's cost structure is asymmetric information,supply chain pricing contract models(a wholesale price contract and an all-unit quantity discount contract)under asymmetric information are proposed by employing the principal-agent principle in a regular scenario.When the retailer's cost distribution is fluctuated by disruptions,we obtain the optimal emergency strategies of the supply chain under asymmetric information by considering deviation costs and show how to effectively handle the cost uncertainty.Using numerical methods,impacts of cost disruptions on the optimal wholesale price,the retailer price,the order quantity and the expected profits of the retailer,the supplier,as well as the total system are analyzed.It is found that the all-unit quantity discount policy can obtain better performance than the wholesale pricing policy.

Stability analysis of intermediate product dynamic price in two-level supply chain

In two cases that upstream and downstream firms have the decision power of intermediate product prices in a two-level supply chain,the dynamic pricing mechanism of intermediate products is studied.When a party who has the decision power of pricing gives prices of intermediate products,the other side will give the supply or demand quantity of intermediate products which maximizes its own profits,then the party who decides price has two pricing strategies.One uses the matching price which meets the other party's demand or supply needs according to the prices of intermediate products in the next cycle.The other uses the convex combinations of the current price and the matching price which satisfies the other party's demand or supply as the price of the intermediate product in the next cycle.No matter which side has the decision power of intermediate product prices between upstream and downstream firms,results show that in the first pricing strategy,only in one case of the pricing of intermediate products stable;but in the second pricing strategy,both of the cases of pricing of intermediate products are stable in a certain field of combined parameters.

Construction and Implementation of CNOOC's Green Supply China

Firstly, the construction background and basic connotations of CNOOC's Green Supply Chain was presented in this paper. Then, a detailed introduction to CNOOC's good practices for building green oil and gas fields, green power plants, green refineries and green chemical plants was given with respect to the establishment of a green production construction and assessment system as well as green exploration, green manufacturing,green products, green sales, green recovery and other aspects. Finally, the effects of the Green Supply Chain established by CNOOC were summarized.

Study on Lead Time and Price Discount in Supply Chain Management

The mathematical model of the demander versus supplier has been presented by adopting optimization theories, the economical order quantity （EOQ） and economic production quantity （EPQ） has further been studied. Then under the consideration of Pareto optimization, a joint decision model of price and lead time discount and lot size has been presented. Further more the sensitive analysis of price and lead time discount are analyzed with an empirical example.
