工程造价市场信息分析及其在线系统开发

Analysis of the Market Information for Engineering Cost and its Online System Development

了解和熟悉某地区的市场信息对工程造价咨询公司在该地区开拓市场及造价工程师在该地区从事业务十分重要。本文旨在探讨如何利用当代信息技术开发一个高性能的信息系统,它能为造价工程师提供及时的、全面和准确的市场信息(以上海地区为例)。系统开发所用的方法是一种改进的生命周期法。按照该方法,首先对工造价市场进行系统分析。然后,基于系统分析的结果,对市场信息进行分类,并在分类的基础上用超文本技术建立信息模型。最后,基于模型开发信息系统。

Knowing and being familiar with the market information of certain a area is very important not only for a consulting company of engineering cost to develop this local market but also for a cost engineer to do his/her business in this area. This paper discussed how to use the state-of-the-art information technology to develop a high-performance information system, which can provide cost engineers with timely, complete and accurate information in an area (using Shanghai as an example). The methodology to develop this system is an improvement on the systems development life cycle (SDLC) methodology. According to this methodology, first a market for engineering cost was analyzed using the systems approach; then, based on the results of this analysis, the market information was classified and an information model was developed using hypertext technology, and at last a system was development.
