Comprehensive Evaluation of China’s Prefabricated Decoration Cost Based on Analytic Hierarchy Process

The development of China’s construction industry is geared towards innovating traditional decoration engineering methods and promoting efficient, energy-saving and environmental-friendly prefabricated buildings. As an important part of prefabricated architecture, the slow development of prefabricated decoration has become one of the reasons that hinder the promotion and implementation of prefabricated architecture. The core problem of business is the high prefabricated cost. Accordingly, this study aims to construct a cost evaluation system with five first_ and 22 second-level indices by using analytic hierarchy process (AHP). Then, the layer-by-layer analysis was conducted. Results show that the design stage has the highest weight in the first_level index, while the second-level index has the highest weight in the decoration scale assembly rate and costs of house type change, installation labor, and production, respectively, which have the most significant influence on the prefabricated decoration cost. Considering that China’s prefabricated decoration has started late, this study uses China’s prefabricated development as an example with the hope of providing reference for developing countries.
