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.

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.

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.

This paper constructs an optimization model based on dynamic game theory, which focuses on the version strategy of information goods in the case that the Types of Consumers are Limited. In this model, utility function is the general type, and the consumers choose the version according to their incentive compatible constraint and participation constraint, while the manufacture makes decision according to maximum profit. This paper argues that the best version strategy for manufacture is the single version. Meanwhile, the price of the best single version and the specific calculation of manufacture's profit are also given in this paper. Based on the profit analysis, technology innovation is the only way to making profit in short term. In the long run, however, only improving the consumers' preference level and consumers' preference distribution can guarantee the sustainable development of information products.

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.

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.

Group-buying on the websites were widely used for B2C transactions by the Youth in China in these years. The names of the group-buying websites were the hot words that people always were talking about. The business model can bring a excellent cash flow and has huge market prospects. As a result, thousands of group-buying websites were built in China. But the increasingly fierce competition makes them get into trouble. The group-buying websites have to rethink the business model right now. They should undertake careful and thoughtful research to investigate how to be unique among the jungle constitutes by these group-buying websites. Actually, group-buying behavior is a relatively complex process between sellers and buyers. Both of them can influence the happening of group-buying behavior. This paper pays attention to the Youth in China. The fact is that the Youth is one of the most important customer groups. We tried to investigate the factors influencing the Youth's attitude to group-buying websites. We carried out a questionnaire survey to the undergraduate students in many universities. In the survey, several variables were involved, including the prices of commodities or services, social influence, fears of opportunism and so on. The results show that social influence is a really significant factor which effects whether the Youth use some group-buying website or not. Service quality is also very important to the process and there is mediating effect between social influence and users' attitudes toward group-buying websites by service quality. In the last section, we address our suggestion to improve the competitive capability of the group-buying websites.

We consider the problem where a group of manufacturers outsource non-preemptive operations to a third-party, where non-preemptive operations means processing operations can not be interrupted when it starts, such as mould making, blast furnace iron making. The manufacturers book time windows announced by third-party with prices and schedule operations in the booked time window. The cost for each manufacturer consists of booking and work-in-progress costs. We address some optimal decision for manufacturers to book time windows and schedule their jobs in the booked time windows so as to minimize their individual cost.

The influence of the negative spillover effect on the different strategies of sales promotion was studied by game theory in dual-channel under Internet environment. The equilibrium results of uniform strategy and non-uniform strategy were analyzed and compared with the integrated decision mode according to the difference of strategies. Combined with the numerical example, the analytical results show that: The wholesale price of the manufacturer was increasing with the negative spillover effect coefficient under the uniform strategy; The proportion of the revenue sharing was decreasing under the inconsistent strategy; The profit and the sales promotion effort of both parties and the profit of the whole supply chain were decreasing under different strategies; The non-uniform strategy was superior to the consistent strategy for the manufacturer and the whole supply chain; The uniform strategy was superior to the non-uniform strategy for the retailer.
