The order of importance is worker wage fluctuation > national policy support > rationality and standardization of splitting > tax policy.
The effective measures to control the cost of prefabricated components are to control the cost of materials and personnel, seek the support of relevant policies and government departments, establish a high-quality talent team and do a good job in fine production management.
Project management technology spreads the wisdom of project management and leads the development of project management..
(2) Among the design factors, the rationality and standardization of component splitting are the decisive factors affecting and controlling the cost of prefabricated components; Among the production factors, the price fluctuation of raw materials and the fluctuation of workers’ wages are the decisive factors affecting and controlling the cost of prefabricated components; Among the factors of transportation and storage, the level of transportation coordination is the decisive factor affecting and controlling the cost of prefabricated components; Among other factors, national policy support and tax policy are the decisive factors affecting and controlling the cost of prefabricated components.

Project management technology is looking for high-quality manuscripts in 2022.
The main research conclusions are as follows: (1) at the criterion level, the influencing factors of prefabricated component cost are production factors > other factors > design factors > transportation and storage factors according to the weight (contribution).
(3) At the index level, the price of raw materials is the most important factor affecting the cost of prefabricated components.
Gansu construction investment technology R & D Co., Ltd., Gansu Lanzhou 730000) selected content, taking the influencing factors of prefabricated component cost as the research object, and building an index system of influencing factors of prefabricated component cost based on design, production, transportation and storage, AHP method is used to analyze and evaluate the influencing factors of prefabricated component cost, and targeted countermeasures and suggestions for prefabricated component cost control are put forward.
