基于BIM的工业化建造管理流程协同度测度研究

Synergy degree measurement of industrialization construction management process based on BIM

为更加客观合理的评价基于BIM的工业化建造管理流程的协同度,构建了基于BIM的协同管理流程框架,并设置5个协同度检测点,以此为测度数据提供支持,采用以D-S证据理论为基础的协同度测度方法对协同检测点的数据进行定量处理。首先,确定协同度检测点评价指标,利用模糊三角函数和白化权函数处理检测点处的灰色信息;然后,将不同检测点的数据信息转换为统一辨别框架下的评价信息;最后,根据不同评价信息的重要度,运用D-S证据合成法则对协同度测度检测点的灰色信息逐级融合。案例表明,该方法不仅能够克服传统评价方法的主观性,还能解决D-S冲突问题,保证建造管理流程协同度综合测度信息融合结果的准确度,基于BIM的工业化建造多方协同管理效果表征更为直观。

For a more objective and reasonable evaluation of BIM -based industrial construction management process of synergy, a collaborative management process framework is constructed based on BIM and five synergy detection points are set to provide support for the measurement data which would be quantitatively processed by the covariance measure based on the D - S evidence theory. Firstly, on the basis of determining the evaluation index of the inspection point, the fuzzy trigonometric function and the whitening weight function are used to deal with the gray information at the detection point Then, the data information of the different detection points is converted into the evaluation information under the unified identification frame. Finally, according to the importance of different evaluation information, the gray information of the coordination degree detection point is merged step by step with D - S evidence synthesis rule. Examples show that, this method can not only overcome the subjectivity of traditional evaluation methods, but also can solve the D - S conflict. It can ensure the accuracy of the fusion of the results of the integrated management of the management process, and the characterization of the effect of multi - party collaborative management based on BIM＇ s industrial construction is more intuitive.
