Abstract: For complex large-scale construction projects (CLCP), each participating entity needs to implement corresponding adjustment and control strategies for the cost deviation generated by the project, and how to scientifically evaluate the control effect is very important for controlling the project cost. However, very little attention has been paid to this area. This paper makes the following innovations and improvements: (1) a scientific and complete indicator system has been established, and the Best-Worst method and K-centroid clustering algorithm have been applied, respectively, to effectively determine indicator weights and expert weights; (2) based on the idea of matter-element extension, an evaluation model combined with a hesitant fuzzy linguistic term set and cloud model is put forward to guide the evaluation of the cost deviation control effect of CLCP; (3) a Chinese case study is conducted and comparative analysis is carried out. The results demonstrate the effectiveness and applicability of the model.

Keywords: CLCP; complex large-scale construction projects; cost deviation control effect evaluation; HFLTS; hesitant fuzzy linguistic term set; cloud model; matter-element extension.
