Abstract:
The green construction evaluation tends to be standardized, but the green construction level evaluation has no unified approach. By establishing the typical index of the green construction scheme evaluation in evaluating its characteristics of energy saving and environmental protection, this paper proposes the ordered weighted geometric averaging operator (OWGA operator) and combined weighted geometric averaging operator (CWGA operator) integration method. The method combines the influence factors of green construction with social and ecological benefit exertion to eliminate the influence of subjective factors caused by expert personal feelings and raise the effect of intermediate value, through assembling expert estimations for indexes from both horizontal and vertical sides, so as to make the scheme optimization results more scientific, reasonable and efficient. Finally, a numerical example is used to prove the practicability, effectiveness and feasibility of the method.
