摘要
绿色施工项目迅速发展,科学合理地甄选具有优秀绿色施工能力的中标单位对绿色施工项目的实施结果至关重要。在借鉴传统施工项目评标指标体系的基础上,结合绿色施工项目的特点和要求,构建了多层次的绿色施工项目评标指标体系。运用C-OWA算子实现评价指标赋权,通过计算施工项目的绿色度进行初步筛选,最终运用向量夹角余弦方法实现评标优选以及指标敏感性分析。该评标模型削弱了专家主观偏好对指标权重产生的不利影响,引入施工绿色度指标以及绿色度等级隶属表,在评标程序中增设初步筛选环节,使评选结果更加客观合理,并将向量夹角余弦与敏感性分析相结合,为投标单位指明弱项。最终,以实例验证该评标模型的可行性和实用性。
Due to the rapid development of green construction projects,scientific and reasonable selection of successful bidder which with excellent green construction ability is essential to the implementation of green construction projects. Combined with the characteristics and requirements of green construction project,this paper established a multi-level green construction project bidding evaluation index system based on the traditional construction project bidding evaluation index system.Using C-OWA operator to achieve the evaluation index weight,through the calculation of the green degree of construction project to conduct the preliminary screening,and the final use of vector angle cosine method for bidding scheme of optimization and index sensitivity analysis. The bid evaluation model weakens the adverse effects of expert＇s subjective preference of the index weight,and green construction index and green degree grade membership table are introducted. Adding initial screening in evaluation procedures makes selection results more objective and reasonable,and the combination of vector angle cosine and sensitive analysis makes bidding units specify weaknesses. Finally,an example verified the feasibility and practicability of the bidding evaluation model.
