研究目的:针对目前铁路建设速度加快,技术标准提高,工程建设项目投资预估算缺乏快速而又准确的方法,在基于铁路项目投资预估算具有一定模糊性特点的基础上,应用模糊数学理论,建立工程项目投资预估算快速预测模型,运用模糊数学的方法和手段,快速对建设项目进行投资预估算,合理确定和控制建设项目投资,提高投资预估算的准确性。研究结论:应用模糊数学理论,建立了项目投资预估算快速预测模型,实现了铁路项目投资预估算预测速度快,简单方便,实用性强,预估算误差满足项目投资预估算精度等多方面的要求,有利于勘察设计过程和建设管理的顺利推进。且可提高设计企业方案竞选的优胜率。
Research purposes: In view of the current speeding up of railway construction, the improvement of technical standards and the lack of a quick and accurate method for estimating investment in construction projects, based on the fuzzy characteristics of railway project investment pre-estimation and the application of fuzzy mathematics theory, The prediction of project investment is a fast prediction model. By using the method and method of fuzzy mathematics, the investment pre-estimation of construction project can be quickly calculated, the investment of construction project can be reasonably determined and controlled, and the accuracy of investment pre-estimation can be improved. Research conclusions: Based on the theory of fuzzy mathematics, a fast prediction model of project investment pre-estimation is established, which realizes the requirements of pre-estimation of railway project investment such as fast prediction, simple and convenient, strong practicability and pre-estimation error to meet the pre-estimation precision of project investment , Is conducive to the smooth progress of the survey and design process and construction management. And can improve the winning rate of the design enterprise program election.
