Research on Identification of Influencing Factors of Prefabrication Building Cost Based on Improved Entropy and DEMATEL Method
In this paper, the fabricated building enterprise which owns component factory is taken as the goal, starting from the three stages of component production, transportation, and installation, and taking the dynamic influencing factors of the construction cost in the process of construction as the main research point. Using the improved entropy and DEMATEL method is to identify the main factors that affect the three stage construction cost of the fabricated building production, transportation, and installation. The weight of influencing factors can be identified objectively by improved entropy method. Applying the identified index weight, and then using DEMATEL method can calculate the degree of influence, affected degree, center degree, and cause degree of each factor. The results showed that: the factors that directly affect the construction cost in the production stage are the complexity of component, the number of new mold, and the number of unqualified components. The factors that directly affect the construction cost in the transportation stage are the type of transportation vehicle, the distance, and the consuming time of transportation. The factors that directly affect the construction cost during the installation stage are the number of hoisting equipment, the number of longitudinal components, and the number of secondary hoisting components. The other factors are affected by the direct factors, which indirectly affect the cost.
