A Forward Selection Method on Customer Credit

In this paper, we discuss a selection and evaluation method of customer credit for the commercial bank loans operation, and put forth a forward selection model by optimization techniques. At last, we also give an example to analyze its application.     

Claremont Colleges Emergency Preparedness: An Action Research Initiative

This study examines the role of knowledge management systems in the context of emergency preparedness at Claremont University Consortium. The research objectives required the researcher's direct involvement with CUC. Canonical action research methodology was used to guide the project. Overall, the client was satisfied with the project's outcome. The researcher designed and implemented an instantiation of a web-based knowledge management system using Wiki technology. This system can assist CUC in overcoming some of its immediate concerns with emergency preparedness. These include the ability of the system to facilitate the communication process, and enable a more structured approach for documenting and storing emergency related information. The system as it exists today is subject to further improvement. This includes the need for continuous training with the system, improving the navigational aspects, and seeking a better fit between the system and the emergency planning and response processes.

用带时序子模块的系统动力学模型预测Brent原油价格

提出在系统动力学模型中加入时序自回归AR(p)子模块，并且自动确定每个AR(p)子模块的阶数p。带时序子模块的系统动力学模型既体现了因素问的横向因果关系，又体现了每个因素的纵向关系。建立欧佩克(OPEC)石油产量、世界GDP、煤炭产量与价格、天然气、需求量、供求差额、消费系数、非欧佩克石油产量、非欧佩克供求差额，石油库存和OPEC组织的期望油价共十一个因素影响下的Brent原油价格预测模型，模型的预测结果表明：在系统动力学模型中加入时序自回归AR(p)子模块的方法是可行的、有效的，并且能提高模型的预测精度。
