E-Supply Chain Incentive and Coordination Based on Revenue Sharing Contract

This paper took the buyer-biased electronic market as an example, where multiple suppliers selling short-life-cycle products are bidding for an order from a powerful buyer with stochastic customer demand. It used a single period newsvendor model to analyze the decision of supplied and buyers to do or not do business online. The results suggest that lack of Incentive is the key factor of B2B electronic markets failure. At the same time, it designed a revenue sharing contract to coordinate the E-supply chain in order to prevent failure of E-market.

Quotient space model based on algebraic structure

In the quotient space theory of granular computing,the universe structure is assumed to be a topology,therefore,its application is still limited.In this study,based on the quotient space model,the universe structure is assumed as an algebra instead of a topology.As to obtain the algebraic quotient operator,the granulation must be uniquely determined by a congruence relation,and all the congruence relations form a complete semi-order lattice,which is the theoretical basis of granularities ' completeness.When the given equivalence relation is not a congruence relation,it defines the concepts of upper quotient and lower quotient,and discusses some of their properties which demonstrate that falsity preserving principle and truth preserving principle are still valid.Finally,it presents the algorithms and example of upper quotient and lower quotient.The work extends the quotient space theory from structure,and provides theoretical basis for the combination of the quotient space theory and the algebra theory.

A Study on Preconditions Setting of Long-Term Contract between Manufacturer and Component Supplier

To provide a risk-sharing mechanism that encourages a component supplier and a manufacturer to expand their production capacity of components and products, many researches on SCM suggested that it is better for the SC players to connect a long-term contract with flexible preconditions before doing the decision-making of production capacity. With considering of the uncertainty of demand and integrity problems between SC players, it is difficult to set reasonable preconditions. As a result, under-investment problems still occur frequently. In this paper, after we had discussed the decision-making of production capacity with the preconditions by analyzing the character of the players, we verified the under-investment problem of the supply chain. In order to clarify the optimum preconditions to alleviate the under-investment problem, we also analyzed the relations between preconditions and supply capacity of the whole supply chain. In the last part of this paper, we proposed a method of preconditions setting in such uncertain situations.

A Comparative Study of Genetic Variation between Chinese Mitten Crab Eriocheir Sinensis and Hepu Mitten Crab E.Hepuensis

Horizontal starch gel electrophoresis was used to investigate the biochemical genetic structure of Chinese mitten crab Eriocheir sinensis and Hepu mitten crab E.hepuensis. Sixteen putative enzyme-coding loci were examined for forty-nine Chinese mitten crabs and thirty-eight Hepu mitten crabs. Nine loci, AAT-1 *, AAT-2 *, G3PDH *, GPI *, IDHP-1 *, IDHP-2 *, MDH-1 *, MDH-2 * and PGM *, are polymorphic in Chinese mitten crab, and seven, AAT-1 *, AAT-2 *, GPI *, IDHP-1 *, MDH-1 *, MDH-2 * and PGM *, are polymorphic in Hepu mitten crab. The proportion of polymorphic loci and the expected heterozygosity are 0.562 5 and 0.080 3 for Chinese mitten crab, and 0.437 5 and 0.075 4 for Hepu mitten crab. The Nei’s genetic distance between two species is 0.002 4.

Compassion in Buddhism and Guanxi： Can There Be a Synergy for Westem Companies in China

Compassion is one of the core fundamental elements of Buddhism. The compassionate virtues are the precious qualities essential in the practice of Buddhism. On the other hand, guanxi plays a dominant role in any successful business venture in Chinese market. This paper develops the understanding of the two ancient bodies of knowledge of Buddhism and Confucianism. The attempt will be made in this paper to understand the deeper meaning of compassion in Buddhism in terms of compassionate virtues such as generosity, discipline, patience, diligence, humility, and wisdom. In guanxi, it will delve into different aspects of guanxi in terms of its background, meaning, significance, different types, intermediary, comparison with networking and ethics and success factors. This paper is based on the literature review on compassion--guanxi. The compassion literature focuses on books on Buddhism and commentaries by great Tibetan Buddhist sages. The guanxi literatures are predominately based on business research papers related to guanxi and business culture in China. The paper provides deeper meaning of compassion in Buddhism. The application of compassion to manage guanxi in China is the topic of this paper. This research is about optimizing the art of guanxi through the application of compassion which will help many non-Chinese business managers to effectively manage it. This paper is considered the first of its kind to study compassion in Buddhism and guanxi practice in China and seeks to provide the necessary framework to conduct the further research on applying compassion to build and manage better guanxi in China.

Effect of Commercial Cellulase Enzymes on Ethanol Production from Pretreated Rice Straw at High Solid Loading

Effect of commercial cellulose enzymes was investigated by batch enzymatic hydrolysis at 15.0% （w/v） solid. It was found that the best commercial cellulose enzyme was Cellic（R） CTec comparing to Accellerase 1000TM and Accelerase 1500TM. The Cellic（R） CTec gave the highest reducing sugar concentration and rice straw conversion. Moreover, when the hydrolysate obtained from hydrolysis using Cellic（R） CTec was fermented by Saccharomyces cerevisiae TISTR 5596, it would give the highest ethanol. In this study, the Cellic（R） CTec was used for fed-batch prehydrolysis prior to ethanol production by simultaneous saccharification and fermentation （SSF） way at 20% （w/v） solid loading. It could produce 35.76 g/L or 4.6% （v/v） of ethanol concentration and 83.67 L/ton dry matter （DM） of yield.

Effect improvement of drug pricing reform based on multi-channel coordination

To improve the effect of the drug pricing reform,a business model of pharmaceutical e-commerce is introduced into the pharmaceutical supply chain.First,based on the measures of the drug pricing reform,a dual-channel model is established,consisting of a drugstore and a hospital.The analysis of the model indicates that the reform leads to higher costs for patients.Then,an e-pharmacy is added to the dual-channel supply chain.Meanwhile,to reduce the home-delivery cost of the e-pharmacy,a multi-channel coordination strategy called“order online,delivery by drugstore”is proposed.By comparing the optimal values under the two models with and without coordination strategy,respectively,the results show that the profits of the e-pharmacy and the drugstore increase while the retail prices of drugs drop,and a large number of patients are diverted from the hospital.Therefore,the business model of pharmaceutical e-commerce with multi-channel coordination can greatly improve the effect of the drug pricing reform.

Commutators of Calderón-Zygmund operators related to admissible functions on spaces of homogeneous type and applications to Schrdinger operators

Let X be an RD-space. In this paper, the authors establish the boundedness of the commutator Tbf = bTf-T(bf) on Lp , p∈(1,∞), where T is a Calderón-Zygmund operator related to the admissible function ρ and b∈BMOθ(X)BMO(X). Moreover, they prove that Tb is bounded from the Hardy space H1ρ(X) into the weak Lebesgue space L1weak(X). This can be used to deal with the Schrdinger operators and Schrdinger type operators on the Euclidean space Rn and the sub-Laplace Schrdinger operators on the stratified Lie group G.

DISPOSING THE LEFTOVERS UNDER THE CONSIGNMENT CONTRACT WITH REVENUE SHARING:RETAILER VS SUPPLIER

This paper studies the consignment contract with revenue sharing where the retailer offers two revenue share schemes between himself and his supplier from the viewpoint of inventory ownership: One is that the retailer takes charge of the unsold items,the other one is that the retailer returns the unsold items to the supplier at the end of the selling period,and the supplier disposes those overstockings.In each contract,the retailer deducts a percentage from the selling price for each sold item and transfers the balance to the supplier.The supplier solves a two-stage problem:She first chooses contract,then decides retail price and delivery quantity according to the terms of the contract chosen.With an iso-price-elastic demand model,the authors derive the retailer and suppliers’ optimal decisions for both schemes.In addition,the authors characterize how they are affected by disposing cost.The authors compare the decisions between the two schemes for disposing cost turn out to be holding cost or salvage value,respectively.The authors use numerical examples to show the supplier’s first-stage optimal decision depends critically on demand price elasticity,the disposing cost and the retailer’s share for channel cost.
