【摘要】：随着国家经济发展,电力需求日趋紧张,输变电建设项目趋于大型化和复杂化。输变电建设项目涉及工程较为复杂,资源需求种类和数量都很可观。如何充分利用资源,且合理控制工期是人们关注的问题。求解多资源受限项目调度问题,采用遗传算法进行关键链识别。在约束理论的基础上进一步创新,得到人们公认较为实用的关键链项目管理方法,它解决了关键路径和计划评审技术所不能解决的资源约束问题。制定的进度计划能够更加切实的反映项目的实际情况,并通过缓冲区设置考虑项目执行过程中多种影响因素。关键链技术研究,主要内容是关键链识别和缓冲区设置。资源约束有单资源、多资源之分,论文讨论多资源约束对关键链识别的影响。项目调度研究逐步趋向于追求工期最短的目标,本文在此前提下,充分考虑工作流程限制和资源约束条件,建立项目调度模型。在确定关键链之后,全方面地思考影响项目工期的多种因素,比如：工作复杂程度、子任务时间占比等。在这些因素作用下,本文深入探索研究,确定在多资源约束下设置缓冲区的模型。最后通过扎哈淖尔输变电工程建设项目的实际案例,应用遗传算法,考虑多资源约束,识别关键链。按照研究模型设置缓冲区,计算工期。通过验证论文提出模型,不仅能减少工期,更重要的是充分考虑了不确定因素对项目调度计划的影响。
[Abstract]:With the development of the national economy, the power demand is becoming increasingly tense, the construction of power transmission projects tend to be large and complicated. The construction of power transmission project involves engineering is complex, type and quantity of resource requirements are very impressive. How to make full use of resources, and reasonable control time is of concern. For multi resource constrained project scheduling problem, identify key chain using the genetic algorithm. Further innovation based on the theory of constraints, people have recognized the critical chain project management method is more practical, it solves the resource constraint problem of critical path and program evaluation and review technique which can not be solved. The plan can effectively reflect the actual situation of the project, and by considering the factors influencing buffer settings a variety of projects in the implementation process. The research of critical chain technology, the main content is to set the key chain identification and buffer resource constraints are. Single resources, more resources, thesis discusses the influence of multiple resource constrained to identify critical chain project scheduling. The research tends to pursue the goal of the shortest time, based on the premise, fully consider the work flow constraints and resource constraints, the establishment of project scheduling model. After determining the key chain, all aspects of thinking influence a variety of factors, such as the duration of the project: the complexity of the work, the sub task time proportion. In these factors, this paper in-depth exploration and research, determined to set the buffer in multi resource constraints model. Through the actual case of Zaha Nur power transmission engineering projects, the application of genetic algorithm, considering the resource constraints, recognition key chain. According to the calculated period setting buffer, research model. To validate the proposed model, not only can reduce the construction period, more important is to fully consider the uncertain factors on the item The impact of the schedule plan.
