基于FAHP-CRITIC和VIKOR法的PC构件供应商评价选择方法

Evaluation and Selection Method of PC Component Suppliers Based on FAHP-CRITIC and VIKOR Method

选择优质合适的PC构件供应商是装配式建筑项目顺利开展的关键。针对PC构件供应商的评价选择问题,提出一种基于FAHP-CRITIC和VIKOR法的评价选择方法。基于包括性能、价格、供货、企业发展及合作5个方面的构件供应商评价指标体系,采用FAHP与CRITIC法分别确定了各评价指标的主、客观权重,采用基于理想点法的组合权重赋权法确定其组合权重;基于此,采用VIKOR法计算出待选供应商的综合评价值并进行优劣排序;最后,通过算例验证了本选择决策方法的实用性与科学性。研究成果可为PC构件采购商提供科学的选择方法,同时也可为PC构件的供应商进一步提升竞争力提供参考。

The selection of high quality and appropriate PC component suppliers is the key for the smooth development of prefabricated construction projects.Aiming at the problem of evaluation and selection of PC component suppliers,an evaluation and selection method based on FAHP-CRITIC and VIKOR method was proposed.Based on the evaluation index system of component suppliers including performance,price,supply,enterprise development and cooperation,the FAHP and CRITIC methods were used to determine the subjective and objective weights of each evaluation index,and the combination weight method based on ideal point method was used to determine the combination weight.Based on this,VIKOR method was used to calculate the comprehensive evaluation value of the suppliers to be selected and rank the advantages and disadvantages.Finally,an example was given to verify the practicability and scientificity of the method.The research results can provide a scientific selection method for PC component purchasers,and also provide a reference for PC component suppliers to further enhance their competitiveness.
