摘要
项目群工期延误诊断是项目群进度目标控制的一项重要任务。总时差可用于判断项目群中某项工作延误对项目群总工期的延误程度,但没有解决某项工作延误对其自身合同项目和后续合同项目工期延误程度的判断问题。本文根据多项目管理和项目群管理理论,通过引入项目群子网络,研究并构建了基于子网络的项目群结构。在此基础上,运用关键路径法(CPM),系统地研究了因子网络中合同项目某工作工期延误对自身子网络以及项目群中后续子网络工期的影响,提出了子网络后主链定理以及前主链总时差定理,从而实现子网络视角下项目群合同项目工期延误的诊断分析。结合算例进行了具体阐述与应用。最后就如何应用人工智能算法实现项目群进度及其影响因素进行实时监控提出研究思路。本文研究成果为子网络承包商的工期延误责任划分以及索赔提供依据。
With the advancement of China’s Belt and Road Initiative,more and more large and mediumsized construction projects are undertaken.They have the characteristics of large scale and complicated relationship between projects.Single project management theory has been difficult to meet the needs of program management.Due to the large number of participants in large-scale engineering projects,the delays between the various contract projects of the program affect each other,and the mutual responsibilities are difficult to distinguish clearly.It can be seen that the problems that need to be solved in the program schedule management are more prominent.The delay diagnosis of program object control is an important task.The delay of the total construction period of a program can be judged by the total float due to a certain work delay,however,the problem that it is not solved is the delay of a certain work contract and the subsequent contract project.It is analyzed that the research and application of artificial intelligence algorithm in program schedule management and the principle of artificial intelligence algorithm.According to the multi-project management and program management theory,the sub-network of the program is introduced and the program structure the sub-network is constructed based on the sub-network.The critical path method is used to study in detail the impact of specific work duration delays on the current sub-network and subsequent sub-network durations in the program in a contract item network based on the sub-network contract item.The concepts such as feature process and subsequent feature process are used to diagnose and analyze the delays of the duration of contract items under the sub-network perspective.Finally,the different delay cases are elaborated and applied in combination with the examples,and the delays of different responsible subjects are divided into:in critical lines or in non-critical lines.According to different delay time,the resulting progress impact is divided into:The impact of the p
