摘要:采用系统动力学理论构建BIM应用项目系统结构,通过分析各变量之间的关系,绘制出存量流量图进行BIM应用项目的经济效益模拟和测算,利用Vensim软件进行存量流量图绘制、模型的检验。根据项目实际应用情况进行分析,提取出项目数据,并运用Vensim软件进行仿真模拟,获取测算更加合理、结果更加精确的BIM应用项目效益情况。选取工程成本、工程错误率、工程返工、工作时间、工作强度、疲劳、管理协助等影响因素对比分析未应用BIM技术的项目的数据情况,分析BIM应用后项目的影响变化,验证了模型的合理性和可行性。
Abstract: The system theory is applied to construct the BIM application project system project. Through the analysis of relationship among different variables, the stock flow graph is drawn to simulate and measure the economic benefits of BIM application in projects. The Vensim software is applied to draw the inventory flow graph and to test the model. According to the analysis on actual application of the project, the project data is extracted, and the Vensim software is applied to conduct simulation to obtain the benefit of BIM application in projects with more reasonable calculation process and more accurate calculation result. Influencing factors, including engineering cost, engineering error rate, engineering rework rate, working hours, working intensity, fatigue, management assistance, and etc., are all selected to compare and analyze the data of projects without applying BIM technology, and to analyze the impact of projects with BIM application, verifying the rationality and feasibility of the model.
