最佳管理措施(BMPs)是非点源污染控制和管理的重要途径,现已成功应用于多个国家和地区,而我国对BMPs的研究尚处于起步阶段。采用模型方法实现区域及流域尺度BMPs的有效实施是目前发展的必然趋势,而对单项BMP的结构、处理效果、影响因素及所需费用等的研究是BMPs模拟和优化的基础。从单项BMP的技术发展和BMPs的模拟、优化方法研究两个方面对BMPs的研究进展进行系统分析和评价:①选取滞留式、生物式、渗透式和过滤式4种类型BMPs中的典型代表性措施进行分析和评价;②从模拟预测模型、优化算法和集成技术3个方面系统分析和介绍相关的模型进展。上述研究认为,我国目前应广泛开展BMPs的基本信息研究和数据积累,在此基础上加大对模型方法的研究和应用,提高决策效率,以实现流域尺度BMPs的有效实施及非点源污染的有效控制。 相似文献

PARTNERING模式最佳实践研究——工作流程再设计 总被引:1,自引:0,他引:1
建筑项目一般都比较复杂,还存在许多不可预计的风险。建筑界存在着诸如在工程参与各方之间缺乏协作,相互信任度低以及沟通交流效率低等问题,这些导致了工程参与各方之间的对立关系。作为一个创新性的工程承发包模式,在过去的20年内,Partnering模式越来越多地在建筑项目中得到应用,它更好地达到了项目目标,并很大程度上减少了冲突和纠纷。对香港近期完成的6个主要Partnering项目进行案例分析,总结使用Partnering模式建筑项目的关键成功要素以及实施的主要障碍。对Partnering模式流程进行重新设计,为更好地在建筑项目中实施Partnering模式提供了方便。在本次研究的成果基础上,设计了一个Partnering模式"最佳实践"的框架结构,建议我国建筑界业者在今后的建筑项目中实施Partnering模式时加以应用。 相似文献

Although the buildability of building designs has not been commonly taken as an important parameter in design quality assessment, previous studies have linked buildability to time, cost, quality and safety performance in many ways. Based on this observation, the question arises of how buildability can be benchmarked and which aspects of project performance can be improved. After identifying available benchmarking tools, the relative correlations are investigated between different buildability attributes and construction performance in terms of time, cost, quality and safety. Based on a questionnaire survey, it was found that construction time performance has strong positive correlations with buildability in the design of external wall elements, simplicity of assembly and installation considerations, while other design attributes affect cost, quality and safety performance to varying degrees. With this understanding, it is postulated that best practice can be promoted among design teams for enhancing buildability, which would in turn raise project performance. Three experienced practitioners have been interviewed for verifying the practicality of buildability benchmarking. As an incentive to improve buildability, benchmarking would help construction stakeholders reap their desired benefits by focusing on the related design attributes in the pre‐construction stage, particularly for functionally oriented buildings. 相似文献

In response to the emergence of scandals involving many high‐profile companies during the 1990s, corporate governance is considered as an area requiring immediate reform. The government of the United Kingdom has conducted a series of reviews on corporate governance and incorporated the recommendations of these reports into regulatory codes. Compliance with these codes can be considered to indicate the implementation of best corporate practice. A question of interest is how UK construction companies perform in corporate governance. The answer can be revealed by comparing construction companies with the top 50 companies listed in the UK, based on the provisions of corporate governance codes. Construction companies are found to (1) disclose less corporate governance information; (2) display lower levels of structural board independence in terms of separate roles of chairman and chief executive officer (CEO) and percentage of independent directors; (3) rely less on external consultant advice in assisting the decision making of three board committees. Research thus should be conducted on whether these disparities cause adverse effects on construction company performance. 相似文献

This paper narrates the project management of the construction of the Florence Duomo by Filippo Brunelleschi in the fifteenth century. This was the most significant dome project in Europe in 1300 years, and possibly the most significant, innovative and complex project of the Renaissance era (Colombo and Lanzavecchia, 1997). It still stands as the largest brick dome ever built. In order to achieve what seemed technically impossible at the time, Brunelleschi researched and adapted the construction and project management of the Pantheon in Rome in the second century. The paper allows us in turn to learn both product and process innovation from this case study, both of which are essential to contemporary project management practice. The case is valuable in understanding key drivers of project management success, and illustrates the substantial potential for learning, and therefore knowledge transfer, from previous historical projects and experiences. 相似文献

The research presents the development of the knowledge value‐adding model (KVAM) for quantitative performance measurement of the community of practice (CoP) of the knowledge management system (KMS) in an A/E consulting firm. The proposed KVAM combines several existing KM theories including knowledge creation spiral, knowledge chain model, and knowledge value added theory to form a process‐level model for measuring the performance of a generic community of practice (CoP). Case study results show that the proposed KVAM provides KM managers with a useful tool not only to monitor the performance of a CoP and its members but also to plan an effective strategy for performance improvement. Unlike the traditional organizational‐level approaches, the proposed KVAM was concluded to better reflect the actual values solely generated by the KMS rather than other management factors. 相似文献

建设工程项目价值是以最优的资源配置有效实现项目利益相关者的需求。政府投资项目评审的价值管理工作处于项目寿命周期的前期阶段,社会公共项目建设应充分考虑到各方利益,因此积极推行价值管理工作是很有必要的。且项目价值分析评价中的某些因素是难以量化的,本文总结了两种价值分析方法的具体应用,并举例进行说明。 相似文献
