【摘要】：工程项目施工进度管理一直是工程项目管理中的重要内容之一,其目标是在一定成本限额及规定的工期内保质完成项目。因此合理的项目施工进度计划和施工中的有效监控是项目进度管理的最重要环节,换句话说,项目进度管理是否成功由计划和监控直接决定。目前编制进度计划的常用方法有横道图,关键路径法和计划评审技术等,横道图虽然简单易用,但只适用于小型项目;关键路径法和计划评审技术均基于网络技术,能运用于中大型项目,但这两种方法在编制计划时仅了考虑工序间的逻辑关系,未考虑到系统内部的资源约束问题和人的行为因素,且在每道工序中考虑了过多的安全时间,这必然会导致依据此方法编制的进度计划不是最合理和可行的计划。基于约束理论的关键链技术提出,为这些问题的解决提供了一种解决思路。本文结合建筑智能化项目的特点,首先,在编制基于关键链技术的项目进度计划时,改进关键链网络图中缓冲区大小计算的方法,该方法考虑了工序内外部影响因素,通过计算工序重要性因子v、工序作业风险弹性因子r和工序复杂度因子c来抵消项目不确定性对施工进度的影响,并采用蒙特卡罗方法仿真来验证该方法的可靠性和合理性;其次,将挣值法引入到关键链项目进度监控,并指出传统挣值法的一些不足,针对这些不足,采用了二级挣值法,即在计算项目挣值的时候,还需分析关键链和非关键链的挣值,这样才能更准确的判断进度偏差原因,有利于项目管理人员有针对性的采取措施。最后,通过运用一个建筑智能化工程实例分析和验证了本文改进的方法和构建的模型能够有效的控制项目进度。
[Abstract]:The construction schedule management of engineering project is one of the important contents in the engineering project management all the time. The goal is to complete the project within a certain cost limit and within a specified period of time. Therefore, reasonable project construction schedule planning and effective monitoring during construction are the most important aspects of project schedule management, in other words, Whether the project schedule management is successful or not is directly decided by the plan and monitoring. At present, the commonly used methods for drawing up the progress plan include the cross track diagram, the critical path method and the plan evaluation technology. Although the cross track diagram is simple and easy to use, it is only suitable for small projects; Both the critical path method and the plan review technology are based on network technology and can be applied to medium and large scale projects, but these two methods only take into account the logical relationship between the processes in the preparation of the plan. Not taking into account resource constraints and human behavior factors within the system, and taking into account excessive safety time in each process, This will inevitably lead to a progress plan based on this method which is not the most reasonable and feasible plan. The key chain technology based on the constraint theory is proposed. This paper combines the characteristics of intelligent building projects, first of all, when compiling the project schedule based on key chain technology, the method of calculating buffer size in critical chain network diagram is improved. In this method, the internal and external factors are considered, and the influence of project uncertainty on the construction schedule is offset by calculating the process importance factor v, the process risk elasticity factor r and the process complexity factor c. Monte Carlo simulation is used to verify the reliability and rationality of the method. Secondly, the earned value method is introduced into the key chain project progress monitoring, and some shortcomings of the traditional earned value method are pointed out. That is, when calculating the earned value of the project, we also need to analyze the earned value of the key chain and the non-critical chain, so that we can more accurately judge the cause of the progress deviation, which is conducive to the project managers to take targeted measures. Finally, An intelligent building engineering example is used to analyze and verify that the improved method and the constructed model can effectively control the progress of the project.
