信息物理融合下的建筑施工现场碳排放实时监测系统

随着全球变暖现象加剧，控制建筑业碳排放成为了重要研究课题，建筑施工现场碳排放的计算与监测问题成为重点。为了有效解决这一问题，梳理了现有碳排放计算方法，总结了各类方法的特点，提出了基于信息物理系统（CPS）技术的施工现场碳排放实时监测系统框架；针对施工现场碳排放计算边界及计算逻辑进行了定义，并从硬件系统与软件系统两部分实现了碳排放实时监测系统的开发。最后，通过无线传感器、服务器、数据库以及客户端的有效耦合，实现了对建筑施工现场的碳排放进行实时监测和数据分析。     

Using Data Mining Techniques to Support Value Management Workshops in Construction

Problem-solving processes in value management （VM） workshops in the construction industry are experience-based, and the quality of these workshops depends very much on the experience of the team members. The efficiency and effectiveness of VM workshops can be improved by better reusing the experi- ence of previous VM cases and field knowledge. This paper describes a new approach to facilitate VM workshops in the construction industry using data mining （DM） techniques. The feasibility of integrating DM techniques with VM workshops in the construction industry is demonstrated in case studies. Examples are presented to illustrate different methods of applying DM tools in VM workshops. The results show that DM techniques can help team members in VM workshops to understand their problems more clearly and to generate more ideas for current problems.     

对城市拆迁中补偿标准的探讨

城市拆迁是中国近几年来的热点问题,拆迁补偿标准偏低被认为是引发拆迁纠纷的主要原因之一.通过建立开发商与被拆迁户两局中人博弈的模型,求解该博弈的混合策略纳什均衡,并分析提高补偿标准对纳什均衡的影响.研究表明,政府单纯出台提高补偿标准的政策,短期内可使被拆迁户受益,但长期的政策效果却降低了拆迁的发生率,减缓了旧城改造的步伐.
