| [8] | From the perspective of hidden cost, an index system of influencing factors of prefabricated buildings cost from five dimensions of design, management, technology, policy, and environment is established, including 13 factors. And the hidden cost analysis model has been proposed based on FISM-BN; this model combines a fuzzy interpretive structure model (FISM) with a Bayesian network(BN). The conclusion is that the probability of hidden costs is 26%. | FISM-BN |
| [9] | From the perspectives of component processing drawing design, mold design, mold production, and use and component on-site production, the strategic planning table is used. This paper summarizes and analyzes the main problems and causes of cost control in the production stage of prefabricated components and puts forward the corresponding control measures. | Strategic planning table |
| [10] | The weight of each index is calculated by AHP. The closeness of four prefabricated high-rise building projects located in Fujian province to the optimal cost is calculated and sorted by the fuzzy TOPSIS method. | AHP, fuzzy TOPSIS |
| [11] | This paper establishes the evaluation index system of prefabricated buildings cost risk from the four aspects of the economy, technology, environment, and management; uses the method of AHP to determine the subjective weight of the index, the improved critical method to determine the objective weight, TOPSIS method to combine the weights; and uses the cloud model to determine the cost risk evaluation level to evaluate the cost risk of prefabricated buildings. | AHP, improved CRITIC, TOPSIS |
| [12] | The strategic planning table method is used to compare the cost between prefabricated buildings and traditional buildings. | Strategic planning table |
| [13] | This paper analyzes the influencing factors of prefabricated buildings cost from four aspects, such as design factors, management factors, technical factors, and policy factors, and calculates the weight of cost influencing factors by using AHP. | AHP |
| [14] | Based on the existing literature and expert opinions, 23 key factors affecting the quality management of prefabricated buildings are summarized, and the hierarchical relationship between factors is analyzed by ISM-MICMAC method. | ISM-MICMAC |
| [15] | Establish the increase and decrease model of the prefabricated buildings project cost before and after “replacing business tax with value-added tax,” analyze and calculate the increase and decrease balance point of the model, and study the influence range and change trend of “replacing business tax with value-added tax” on prefabricated buildings cost. | |
| [16] | A hybrid model is used to evaluate the environmental impact of prefabricated buildings and traditional in-situ cast buildings in the building life cycle. | A hybrid model |
