Building Cost Control Model of Assembly Construction Project Using Analytic Hierarchy Process

To further understand the factors that affect the cost of prefabricated building, this paper adopts the strategic cost driver theory to analyze the factors which affect the cost of prefabricated building. Through a large number of literature research and practical research, we analyze the cost composition of prefabricated buildings and the factors affecting the cost of prefabricated concrete buildings. Through the establishment of AHP model, we calculate the weight of each index, use the form of table to summarize the weight of each level, get the corresponding evaluation, and analyze the advantages and problems of cost control in each stage of the project. Finally, according to the analysis results of the prefabricated concrete construction project, certain reasonable measures and suggestions are provided to reduce the cost of the prefabricated building from several aspects.
