In the IT industry, software maintenance after system delivery is a major concern for any system development team. Software maintenance involves system updates for new customer requirements and error corrections within the delivered software. The management of maintenance is the service management of IT products, the cost of which can account for more than 50% of the total development budget. A major reason for the high cost is the changes brought about by the software updates and error corrections. Inconsistencies in the changes occurring in software development and service management afterwards cause confusion and misunderstanding, leading to further difficulties of maintenance, which enevitably result in further cost increases. To keep the consistency of software products and improve the service management in IT software products, software configuration management(SCM) is an approach. Here, a conceptual framework is set up to introduce relationships between the four areas of SCM and implement mandatory referential integrity between them within the software development stages, then maintain these enforced relationships between stages. It can set up rules to ensure mandatory integrity in changes, retaining consistency and improving Service Management. It is flexible enough to apply with any development models, waterfall, rapid prototyping, spiral development, etc.

Many companies' distribution center need to lease containers to delivery the cargos according to the received orders and cargoes need to be packed into containers before they are delivered by airplane. In this study, a dynamic programming method is brought forward to solve this problem based on the solution of a mix-integer linear programming sub-problem. The mix-integer linear programming sub-problem is used to select container selection and optimize cargo loading, and dynamic programming method is used to optimize container leasing plan for orders within a certain period. The numerical tests show the method is efficient and great cost can be saved.

This research seeks to provide a Weblog-based knowledge management solution to solve the problem of knowledge sharing and knowledge creation in organizations. The methods include literature analysis and discussion with experts. We first examine the major problems of technology-oriented knowledge management model in knowledge sharing and knowledge creation: the emphasis on explicit knowledge, and the 'push' style that neglects the demand and motivation of individual. And then, by synthesizing and integrating relevant material, we propose a systematic Weblog-based knowledge management model of a 'pull' style and a practical implementation method in order to solve the problem of former model. By discussing the weaknesses of Weblog-based model - incompleteness in knowledge capturing and uncontrollability in management, we recommend that the best implementation is to combine the advantages of both models in order to form a two-way and cyclical Weblog-based model.

This paper analyzes the coordination of returns policy for single-period supply chain under supplier and retailer, the later has been constrained by downside risk. We model the decision problem with newsboy model and then analytically derive the optimal policies of the supply chain. Compared with the case of no risk constraints, the study has shown that the expected profits of both members of supply chain have been reduced under the control of the returns policy. Accordingly, the "least risk sharing" is optimal choice for both parties. We close with a discussion of contract implementation issues and future research.

In this paper, the value relevance of asset impairment of the loss listed companies is studied. The study shows: in total, the value relevance of the accounting earnings of the loss listed companies is enhanced after the allocation of impairment of asset reserves. The impairment reserves data itself has value relevance. Meanwhile,this paper find that the value relevance of accounting earnings of the loss listed companies in the loss year is less than that in profitable year; the accounting information in profitable year is more useful for investors.

A new method of Fuzzy neural network to estimate the contribution of different education level on human capital has been proposed in this article. By using fuzzy neural network mapping, this article has estimated the contribution of education on human capital at four levels (illiteracy & primary, junior, senior and higher) in three regions of China with different science and technology level. It is possible to conclude that the contribution of education in these three regions is remarkably different. Education itself does not necessarily have positive impact on actual human capital. Illiteracy & primary may have negative impacts in certain regions. Meanwhile, non-educational factors have significant positive impacts on human capital.

Customers' switching behavior analysis plays an important role in affecting market share and profitability of service providers. Existing researches mainly focus on the service provider selection criteria. Based on these studies, we propose a dynamic simulation model to study the impact of service performance changes on customers' switching, and the corresponding influence on the changing of market share and profitability of service providers. Our model can integrate common variables which may influence switching such as service performance, customers' satisfaction, loyalty, social interactions and so on, which can get quantifiable and reasonable dynamic simulation results. Simulation results are also provided.

The effect of return on price and profit of manufacturers and retailers in chain to chain competition is examined under uncertainty yielding several new and important conclusions. First, within certain range of demand uncertainty, the return policy is win-win for manufacturers and retailers, and improves efficiency of the whole supply chain. As the intensity of competition increases, the win-win range becomes more robust. By contrast, monopoly supply chain is impossible. On the other hand, when the uncertainty is less than another boundary, manufacturers have strong motivation for the returns policies. We demonstrate that in general, returns policies intensify the competition among retailers, however, within some range of demand uncertainty, returns policies mitigate the competition among manufacturers and otherwise, intensify the competition among manufacturers which leads to a decrease in wholesale price. Those results enlarge current conclusions with related return policy.

Though P2P (peer-to-peer) technology makes it possible that the number of the clients can be infinite, P2P technology still has some problems, for instance, instability and fluctuation, which may influence the quality of service (QoS). In this paper, two novel P2P-based architectures are proposed, which can avoid the system fluctuation caused by the new joining nodes or the departing nodes. And a new incentive mechanism is introduced, which can well motivate the clients to be seeding server. Analysis of the number of the nodes and the benefits of the issuers shows that this incentive mechanism can guarantee system reliability and solve the problems of scalability, QoS, and the benefits assignment of the server issuers.
