One of supply chain management concepts, strongly conditioned upon inter-organizational integration, is demand planning, encompassing a sequence of activities concerning the coordinated flow of demand through companies, effectively supported by specific methods and technical instruments. The paper seeks to explore the contribution of multidimensional aspects of supply chain integration in the methods and instruments supporting demand planning process. In order to achieve this goal, the research methodology was employed. Having performed a Principal Component Analysis (PCA) with varimax rotation in a space of the variables manifesting supply chain integration, the constructs were extracted and employed as classification criteria in a cluster analysis. The results of the study show that the examined supply chains may be grouped into three classes having distinct characteristics. The findings of the paper demonstrate the types and intensity of the use of methods and instruments supporting demand planning process regarding the level of supply chain integration.

The selection and scheduling of a portfolio of projects is a task frequently found among the strategical activities performed by management staff in several industries. When choosing a project to be selected and scheduled into a portfolio, managers have to deal with conflicting criteria, resource constraints, distinct scenarios, and changes during the planning and execution phases. In this work, we describe the functionalities of a decision support system (DSS) prototype designed to help managers make better decisions, when constructing a portfolio of projects. The DSS software was developed to solve portfolio selection problems originating at a large corporation in the power generation industry. It implements a heuristic algorithm, which finds solutions at least 10% better than a manually produced solution for a real-world input instance.

The Internet-enabled lending market is developing rapidly. As a financial innovation market, the regulatory mechanism should be paid attention to control the market risk. The questions of how to regulate become serious. This paper tries to illustrate the regulatory strategy in Internet-enabled lending market by theoretical-game model.

This paper studies the effects of channel power structure and participants' risk-averse attitude on differentiated pricing policies of closed-loop supply chains. It is assumed that the manufacturer is risk-averse and the retailer is risk-neutral. The manufacturer's expected utility function and the retailer's expected profit function are obtained by mean-variance theory. Then the differentiated pricing policies and profit allocation problem are discussed under three channel power structures: manufacturer-Stackelberg (MS), retailer-Stackelberg (RS) and Vertical Nash (VN) equilibrium. The optimal wholesale prices, retail prices and production quantities of new manufactured products and remanufactured products are derived and compared under different cases. Finally numerical analysis of risk-averse degree on participants' profits is given. The study has shown that the VN mode yields the best closed-loop supply chain performances, and then is the MS mode, the worst is the RS supply chain.

This paper discusses the liquidity premium based on three-moment capital asset pricing model. The study sample is A-share listed in Shanghai and Shenzhen stock exchanges before January 1997. The study is to test whether the three-moment model is able to explain the liquidity risk completely, and whether there is illiquidity premium in China's stock market. The empirical results indicate that three-moment model does not capture the liquidity premium adequately, and liquidity premium exists in China's A-share market. In addition, the empirical results reveal that investors have a preference for positive skewness, which they are willing to pay for.

A customer relationship management (CRM) system is an innovative system which is widely used to support collection, integration, and analysis of customer information. The effectiveness of CRM systems depends on the data fed into it; however, there has been little academic research on the customer information quality in CRM systems. Therefore, this study sets out to examine the factors that play a tangible role in enhancing customer information quality in CRM systems. Data were gathered from 93 financial services firms in a field survey. Our results suggest that the impact of customer-information quality in CRM systems on organizational performance starts with infrastructure capability supporting for CRM systems and CRM systems supporting for customer orientation. Moreover, our results indicate that customer information quality positively impacts customer relationship performance, which, in turn, leads to improvements in overall organizational performance.

This paper investigates the impact of the TQM implementation on financial performance of the firm by a sample of public companies that have won China Quality Award from 2001 to 2007 in the mainland of China by using Event study and Panel analysis methods. Our results show that the market share enjoys a significant increase, the ratio of cost to sales is remarkably increased, the asset turnover rate does not change significantly, and the return on total assets shows a significant decrease since firms have won the quality awards. The changes of financial performance of quality award winners are different with companies' size, capital intensity, degree of diversification and the time of awards announcement. In window periods sample firms which are larger, low diversified and newly quality awards winners have better financial performance than other sample firms, the degree of capital intensity has no effect on the financial performance after implementing TQM.

Tourists may rely on external information to make various decisions. By understanding the relation between information source characteristics and decision making, tourist operators can improve their communication and marketing efforts. Some businesses use corporate blog as a communication platform to engage their customers with the companies. Researches about the causal relationship between corporate blog and business marketing performance, yet, are scant. Based on 143 samples collected by questionnaire survey, this study found that vividness, interactivity of the blogs impact B&Bs' lodging intention via the mediation of the sense of intimacy; and that direction (positive/ negative) of product reviews posted in the blogs directly impact the lodging intention.

Performance-based contracting (PBL), as a novel approach, is replacing traditional service procurement practices. In this paper, we set up a closed-loop support system for repairable parts with an M/M/m/N queuing service facility and a spare parts warehouse. We derived the steady-state probability of inventory levels in warehouse and the performance measures of the support system. Under the performance-based contracting, we propose optimization policies for the support system.

Group buying price (GBP) mechanism is a useful pricing mechanism in online selling. In this study, we focus on the case that buyers are small retailers, and there are two suppliers in the market. Retailers' ordering choice is discussed, and we also study how the supplier should set the GBP price curve. The conclusion shows that to beat the fixed price, the supplier should not use a small slope price curve. And retailers' group buying is not always better for the supplier.
