Abstract
Scientific selection of building materials supplier is of great importance in the management of construction projects. In this work, the selection problem of building material suppliers is investigated under the background of economic globalization based on the IFAHP approach. Firstly, according to the features and key factors of building materials supplier selection, this work constructs evaluation index system by taking five aspects including cost, quality, service level, supplier qualification and risk into account. Secondly, the intuitionistic fuzzy preference relations (IFPRs) of criteria or sub-criteria and IFPRs between the alternatives with respect to each sub-criterion are determined via paired comparisons. The consistency check is carried out subsequently. Considering that the interaction process between experts and decision makers is time consuming and the experts may be not willing to participate in the adjustment and correction of IFPR continuously, an algorithm is proposed to automatically correct the inconsistency while preserving the original information even without experts involved. Consequently, the time costs of experts can be greatly shortened. Based on the above analysis, the optimal scheme can be obtained via calculating the scores of each material supplier. A case study on the selection of building material suppliers is conducted by employing the proposed framework. Results show that the scores of the three suppliers is positively correlated with the weight of the cost but negatively correlated with that of quality, service level, supplier qualification and risk. Besides, the sensitivity analysis illustrates that product quality and service level affect the ranking greatly.

Summary
As the development and management methods of the construction industry are increasingly mature, more and more industry managers pay attention to the selection of building materials suppliers. Substantial results on material suppliers’ selection based on multi-attribute decision making method have been reported [14,15,16,17,18,19,20,21,22,23,24]. In Li et al [20], the weight of the evaluation index system was determined through the objective assignment method- information entropy method, and the 4PL supplier optimal decision model was utilized to improve the supplier selection approach based on gray correlation coefficient. How to shorten the time consumed during the interaction process between the experts and decision makers when select a suitable building material supplier? Responding to the above discussions, this paper studies the problem of selecting building materials supplier under the VOLUME 8, 2020 background of economic globalization based on the IFAHP. The sensitivity analysis illustrates that product quality and service level affect the ranking greatly
