The impact of China's exports on global manufactures prices

This paper analyses the impact of China's exports on the prices of exports from other countries using disaggregated import data in the US, EU and Japan over the 1989-2006 period. Findings from this study suggest that China's exports have affected not just those countries whose competitiveness is largely based on low wages but all country groups in certain products sectors, destination markets and during different time periods. The middle income countries are the most affected by China's export expansion through price competition particularly after the late 1990s as a consequence of China's market expansion, its WTO entry and exchange rate variation. The influence on high-income countries is only in low-technology product sectors and appears to lose its significance in the post-1997 period. The impact on low-income countries is only significant in the medium- and high-tech sectors mostly in the pre-1997 period and this effect weakened over time

Dynamic Surgery Assignment of Multiple Operating Rooms With Planned Surgeon Arrival Times

International audienceThis paper addresses the dynamic assignment of a given set of surgeries to multiple identical operating rooms (ORs). Surgeries have random durations and planned surgeon arrival times. Surgeries are assigned dynamically to ORs at surgery completion events. The goal is to minimize the total expected cost incurred by surgeon waiting, OR idling, and OR overtime. We first formulate the problem as a multi-stage stochastic programming model. An efficient algorithm is then proposed by combining a two-stage stochastic programming approximation and some look-ahead strategies. A perfect information-based lower bound of the optimal expected cost is given to evaluate the optimality gap of the dynamic assignment strategy. Numerical results show that the dynamic scheduling and optimization with the proposed approach significantly improve the performance of static scheduling and First Come First Serve (FCFS) strategy

Network value and optimum analysis on the mode of networked marketing in TV media

Purpose: With the development of the networked marketing in TV media, it is important to do the research on network value and optimum analysis in this field. Design/methodology/approach: According to the research on the mode of networked marketing in TV media and Correlation theory, the essence of media marketing is creating, spreading and transferring values. The Participants of marketing value activities are in network, and value activities proceed in networked form. Network capability is important to TV media marketing activities. Findings: This article raises the direction of research of analysis and optimization about network based on the mode of networked marketing in TV media by studying TV media marketing Development Mechanism , network analysis and network value structure.Peer Reviewe
