基于灰色聚类法评判模型的铁路绿色r施工项目评标方法研究

摘要

With the continuous promotion of railway green construction, the green construction enterprises have become the focus of attention of tenders. In order to improve the traditional evaluation method, we redefine the green construction bidding process and establish a reasonable evaluation index system of railway green construction, and construct the AHP-Gray Clustering Bid Evaluation Method by combining the analytic hierarchy process with the gray system theory Method. In order to make the evaluation index meet the requirements of quantitative analysis as far as possible, and by taking the maximum possible resolution of human thinking ability into consideration, the indi-cators are divided into excellent, good, medium, qualified, slightly poor, poor 6 gray grades, and are respectively as-signed scores, which forms a vector of evaluation index level value. The weighted average is calculated and the over-all score of every tender is obtained by combining the assessment results of the merits and demerits of the indicators with the level value of vector, and the final order of merits and demerits is determined to choose the best winning bidder for the owners. Finally, this evaluation model is applied to the ZhongChuan Railway project for empirical analysis, which verifies the feasibility of the method in the green construction project evaluation.%随着铁路绿色施工的不断推广,择优选取绿色施工企业已成为招标人日益关注的焦点问题.为改进传统评标方法,将重新确定绿色施工评标流程,建立合理的铁路绿色施工评标指标体系,并采用层次分析法与灰色系统理论相结合的方法,构建AHP-灰色聚类法评标模型.为尽可能使评价指标满足定量化分析要求,同时考虑到人体思维最大可分辨能力,将各指标划分为优、良、中、合格、较差、差6个灰类级别并分别赋值,形成评价指标等级值化向量.然后,通过评标专家对投标书中各指标评定的优劣等级结果与其等级值化向量进行加权平均,计算出各投标书综合得分,确定最终优劣排序,为业主选取最优中标人.最后,运用此评判模型对中川铁路项目投标书的实证分析,验证了该方法在绿色施工项目评标中实施的可行性.
