We study how the search engine should update its reserve price in a sponsored search auction for a particular keyword given a certain number of ad links are sold. Different from a static auction where the optimal reserve price is proved to be constant, in a dynamic setting the optimal reserve price is dependent on not only advertisers' per-click values, but also the number of ad links sold. A search engine should gradually raise reserve price as more qualified advertisers arrive, and maintain the same threshold after all first-page positions are occupied.

This paper studies how the two players in dynamic game decide trade credit term respectively by considering a default risk component. Relationship of those two credit terms has a great influence on default event, since capability of the retailer making payment is related to this relationship. A bilevel programming model with unit cost minimization objectives to the supplier, who serve as the “leader”, is set up to determine the credit term by incorporating the predictive credit term offered by the retailer and default risk. Unit return maximization to the retailer is used to obtain the optimal credit term offering to consumers and procurement policy. Hence, the decision-making process of those two credit terms is a dynamic game process. Numerical experiments show that the rate of change of demand on the retailer's credit term is the most important factor determining the credit term offered by the supplier.

The factors of the knowledge innovation in service-oriented manufacturing industry supply chain is analyzed in this paper based on the literature on service-oriented manufacturing, supply chain and knowledge innovation, and a influencing factor system of service oriented manufacturing industry supply chain knowledge innovation is constructed. Then, the investment of knowledge innovation of technical, management and market is taken as the input factors, and the income rate of net assets is taken as the output factor to construct a data envelopment analysis mode(DEA) according to the characters of supply chain. According to the quantity relationship of the input and output factors in DEA model, the effect to service-oriented manufacturing supply chain knowledge innovation from the ability of knowledge innovation of technical, management and market can be analyzed. The outdoor sports club is taken as a typical example to verify the effect of the influencefactors.innovation investment, influence factor, data envelopment analysis(DEA).

Various theories related to knowledge creation have been proposed by academics and practitioners in business. Most knowledge-creation theories are focused on knowledge transfer and development by a firm-centered view, such as the SECI model. In the meantime, the customer-centered view is highlighted in marketplaces instead of the firm-centered view due to the concept of value-in-use. Since knowledge creation is treated as a main force to deal with complicated marketplaces in today's economy, knowledge creation has been essential with customer value creation. In this paper, we distinguish the SECI model and the KIKI model on knowledge creation. The SECI model is proposed for knowledge conversion between two knowledge types by an interaction dynamic in an organizational context. The KIKI model is proposed for value co-creation based on knowledge creation by a service approach, which is a justification process in knowledge creation towards customer value creation. This paper gives two innovation cases to reveal the distinguishable implication between the SECI model and the KIKI model for knowledge creation.

Trade credit insurance, as one of the most important risk management tools, has been widely used in companies' general operation. In this paper, we study a supply chain with a manufacturer and downstream partners (buyers). The manufacturer who allows its downstream partners to delay payment for goods already delivered, purchases trade credit insurance to transfer the non-payment risk, and loans money from the bank to deal with the capital constraint problem. Using Stackelberg game and loss-averse theory to establish newsboy model with trade credit insurance, this paper characterizes the optimal insurance coverage and total sales of the manufacturer as well as the interest rate decision of the bank.

Information plays an important role in the decision process of risk management in a Virtual Enterprise (VE). The private information between owner and partners is a gap, which hinders the optimal decision of risk management for the whole VE. This paper studies the impact of asymmetric information on decision results of risk management in the VE, and gives useful advices to improve the information situation between owner and partners. More specifically, Distributed Decision Making (DDM) theory and stochastic programming theory are employed to build a significant model to describe the decision process of risk management. A Two-Level Particle Swarm Optimization (TLPSO) is then designed to solve the resulting optimization problem. The result shows that the proposed algorithm is effective and the proposed model can help to improve the description of the information situation between the owner and the partners, which is helpful to reduce the risk of the VE.

The objective of this paper is to reveal the factors that determine customers' satisfaction of eMarketplaces in Saudi Arabia. Six hypotheses were postulated based on an extensive literature review in terms of security, complementary services, strong infrastructures, reliability and regulatory requirements of eMarketplaces. A survey (n=337) was carried out using convenience online tools. The sample comprised participants who have involved on eMarketplaces activities. Participants then been divided into two different groups based on their age, experience and their involvement in the technology. The first group was students (n=156) and the second group was non-students (n=181). An exploratory factor analysis followed by a confirmatory factor analysis run in SPSS which been used to test the validity of the model for each group. The survey results support all five factors from the original model with differences between the two groups regarding the strong infrastructures and regulatory requirements factors, indicating that the modified, model labeled M2 can be utilized in enhancing customer satisfaction with eMarketplaces among Saudi users.

Coordination mechanisms are proposed in a supply chain consisting of one supplier and one retailer with supplier's cost asymmetric information in a normal scenario firstly. After supplier's cost disruption has occurred, coordination mechanisms for revising production plan in a irregular scenario are developed. Impacts of supplier's cost disruption on retail price, wholesale price and retailer's as well as supplier's expected profits are investigated through analytical and numerical analyses.

We consider a two-period production and pricing model under a coupon recycling environment, in which a monopolistic manufacturer is able to produce and sell new, remanufactured and upgraded products simultaneously in the market. To attract consumers to return used products and promote the sale of upgraded products, the manufacturer offers coupons in the recycling process. We focus on the competition between different kinds of products and analyze the manufacturer's optimal production and pricing strategies as well as the effect of coupons on them.
