基于云物元模型的装配式建筑绿色性评价

Green Assessment of Fabricated Building Based on Cloud Matter Element Model

结合《中国绿色建筑评价标准》与装配式建筑特点,基于全寿命周期理论,从设计、生产运输、施工、运营管理、报废与回收5个阶段建立装配式建筑绿色性评价指标体系。在此基础上,提出云物元评价模型,并运用主观赋权法—AHP和客观赋权法—熵权法确定指标的综合权重。通过指标与绿色性等级之间的关联度计算,根据隶属度最大原则,由此得出装配式建筑绿色性等级。并通过案例验证了云物元模型能够克服了绿色性评价的随机性、离散性和不确定性,为装配式建筑绿色性评价提供了新的思路。

Combining the China ＂Green building evaluation criteria＂ with characteristics of fabricated building, an evaluation index system for fabricated building was established based on the whole life cycle theory from the following 5 dimensions： design, production transportation, construction, operation management, and recycling. On the basis of this system, the paper puts forward a cloud matter element model. In addition, the method of objective weighting entropy and subjective weighting included AHP are used to determine the overall index weight. Then the cloud correlation degree between each index and the green score is calculated. According to the maximum principle of membership, the green grade is calculated. Finally, the case study shows that cloud matter element model can overcome randomness, discreteness and uncertainty, which provides a new idea and method for the green evaluation of the fabricated building.
