【摘要】：项目后评价不仅可以用来对项目进行科学的总结,还可以为之后类似项目提供借鉴参考,是一种有效的项目管理手段。在后评价工作中,针对工程项目施工阶段的后评价是非常关键的部分。从目前现状来看,针对工程项目施工阶段的现行后评价方法主要有前后对比法、有无对比法、成功度法和综合评价法。然而这些方法由于自身存在缺陷,单纯用其对公路项目施工阶段进行后评价已经无法达到良好的效果,得出的后评价结论往往达不到应有的水平和高度,一定程度上还会阻碍公路项目后评价工作在中国的推广。作为一个能够综合考虑项目内多个因素的评价方法,挣值法的特点比较符合项目后评价的要求。若将其应用到针对公路项目施工阶段的后评价中,可望能够提升后评价结论的效用。针对这种情况,作者想到借鉴传统挣值法的思路,试图去寻找一种能够将质量与成本、进度因素集成量化的方法,来改进传统挣值法,以弥补现行后评价方法的缺陷。该文基于对现行几种针对公路项目施工阶段的后评价方法和挣值法基本原理的综述,发现可以将挣值法引入公路项目施工阶段的后评价。针对传统挣值法无法直接用于事后评价的缺陷,利用曲线拟合法将质量因素量化后对传统挣值法进行了改进。最后将改进后得到的RQC挣值法引入公路项目后评价案例,通过案例分析的方式来验证这一做法的效果,并展望了 RQC挣值法引入针对公路项目施工阶段的后评价时还需要注意的问题。该文的主要研究结论有三点:第一,单纯使用现行方法对公路项目施工阶段进行后评价,达不到后评价应有的要求。第二,将引入质量因素改进后的挣值法用于公路项目施工阶段的后评价,既有必要,又切实可行。第三,初步创建了基于质量要求达成度的RQC挣值法,这一方法可以提升公路项目后评价的效果。该文主要的创新点在于:第一,尝试用曲线拟合法来对质量进行量化,按照质量要求的内涵,首次提出了可以从质量的明示要求和隐含要求两个方面对其进行综合评价的系数RQC。第二,将质量因素引入挣值法后,弥补了传统挣值法的缺陷,得到了升级后的RQC挣值法。第三,该研究针对公路项目后评价创建RQC挣值法的思路,同样可以适用于其他类型的项目后评价。
[Abstract]:Post-project evaluation not only can be used to summarize the project scientifically, but also can provide reference for similar projects. It is an effective means of project management. The post evaluation of the construction phase of the project is a very important part. From the current situation, the existing post evaluation methods for the construction phase of the project mainly include the method of comparison before and after, whether there is a method of comparison or not. The method of degree of success and the method of comprehensive evaluation. However, due to their own defects, the method can not be used to carry out the post-evaluation of the construction stage of the highway project. The post-evaluation conclusions are often not up to the required level and height, and to some extent will hinder the promotion of post-evaluation work in China. As an evaluation method that can comprehensively consider many factors in the project, The characteristics of earned value method are more in line with the requirements of post-project evaluation. If it is applied to the post-evaluation of highway project construction phase, it is expected to enhance the effectiveness of the post-evaluation conclusion. In order to improve the traditional earned value method, the author tries to find a way to integrate the quality, cost and progress factors to improve the traditional earned value method. In order to make up for the defects of the current post-evaluation methods, this paper summarizes several existing post-evaluation methods and the basic principles of earned value method for the construction stage of highway projects. It is found that the earned value method can be introduced into the post-evaluation of highway project construction stage, aiming at the defects that the traditional earned value method can not be directly used in the post evaluation. The traditional earned value method is improved by using curve fitting method to quantify the quality factors. Finally, the improved RQC earned value method is introduced into the post-evaluation case of highway project, and the effect of this method is verified by case analysis. The paper also looks forward to the problems that should be paid attention to when the RQC earned value method is introduced into the post evaluation of highway project construction phase. The main conclusions of this paper are as follows: first, only using the current method to carry out post-evaluation of highway project construction phase. Second, it is necessary and feasible to apply the improved earned value method of quality factor to the post-evaluation of highway project construction stage. The RQC earned value method based on the degree of achievement of quality requirements is initially established, which can improve the effect of post-evaluation of highway projects. The main innovations of this paper are as follows: first, try to use curve fitting method to quantify the quality. According to the connotation of quality requirement, the coefficient RQCwhich can be comprehensively evaluated from two aspects of explicit requirement and implied requirement of quality is put forward for the first time. Secondly, the quality factor is introduced into earned value method, which makes up the defect of traditional earned value method. The RQC earned value method after upgrading is obtained. Thirdly, the idea of creating RQC earned value method for highway project post evaluation is also applicable to other types of post project evaluation.
