基于网络协同的建设项目价值管理系统

A CSCW-based value management system for construction projects

价值管理(Value Management,VM)是降低建设项目成本和改善项目执行效率和质量的一个重要途径,然而,VM在我国建设领域中还存在应用不足、认识不够、相关法律法规不完善以及成效不显著等问题。由于工作计划不同、技术手段差异以及不支持远程协同等因素的影响,针对香港建设领域开发的交互式价值管理系统(IVMS)难以直接应用于内地。为此,本文在IVMS基础上,提出了适用于我国建设领域VM实践的价值管理系统IVMS-CN。IVMS-CN是一个基于网络协同的群体决策支持系统,它由网络通讯平台、协同平台和管理平台等三部分组成,能够为用户提供一个远程协作环境和群体决策支持平台,实现远程参与VM研究,并促进参与者之间的信息交流和共享,减少过程损失,增加信息增益,从而实现VM研究效率与质量的提高。

Value Management （VM） is an effective approach to reduce the cost and improve the process effectiveness and efficiency of construction projects. However, many problems such as lack of people＇s awareness, lack of implementation guideline and lack of promotion policy have greatly limited the applications of VM in the Chinese construction industry as well as the output quality. The Interactive Value Management System （IVMS）＇ that is developed based on the practices of VM applications in Hong Kong＇s construction industry cannot be effectively adopted in China's Mainland, due to the differences in job plans, approaches and the fact that IVMS does not support remote CSCW. Based on the VM practices in the Chinese construction industry, a CSCW-based value management system named IVMS-CN is proposed. IVMS-CN is composed of a network-based communication platform, a CSCW platform and a management platform. It aims to provide a remote collaborative environment and a group decision support platform for VM members so that they can take part in VM studies in different places. IVMS-CN can also facilitate the communication and information sharing between VM members, reduce process losses and improve process gains so that the qualities and effectiveness of VM practices in the Chinese construction industry can be improved.
