Cost increment prediction method and device for fabricated building and computer program product

The invention provides an assembly type building cost increment prediction method and device and a computer program product, and the method comprises the steps: calculating the unit price of the assembly per building area of a component through the assembly proportion, the assembly work amount and the assembly unit price of the component in an assembly design scheme, and replacing the pouring work amount and the pouring unit price of the pouring component to obtain the cost increment of the assembly type building. And calculating to obtain the unit price of pouring per building area of the alternative pouring component, and finally calculating to obtain the cost increment of the fabricated building to be predicted based on the unit price of assembling per building area and the unit price of pouring per building area. Therefore, by adopting the scheme of the invention, the prediction of the cost increment of the to-be-predicted fabricated building is realized, the balance between the assembly rate and the cons
