摘　　要：为解决经典关键链缓冲区设置方法中,因不确定性因素量化得不合理而造成的装配式建筑施工工期的延误问题,主要考虑影响装配式建筑施工进度的3类因素,利用信息熵理论提出一种基于复杂熵、多资源熵和项目团队熵的缓冲区设置方法;重点引入偏最小二乘法结构方程模型解决项目团队熵难以度量的问题,并给出缓冲区设置及修正的熵模型;通过算例仿真,验证了本研究缓冲区设置方法的可行性。该方法可有效地缩短装配式建筑项目的完工工期。In order to solve the problem of delay in construction of prefabricated buildings caused by unreasonable quantification of uncertain factors in the classic critical chain buffer setting method,mainly considering three types of factors affecting the construction progress of prefabricated buildings,a buffer setting method based on complex entropy,multi-r esource entropy and project team entropy was proposed based on the theory of information entropy.Partial least squares structural equation modeling was mainly introduced to solve the problem that project team entropy was difficult to measure,and an entropy model for buffer setting and correcting was proposed.The feasibility of the buffer setting method proposed in this study was verified through the example simulation.The method can effectively shorten the completion period of the prefabricated building project.
