【摘要】：在企业的日常运营和发展中,项目管理能够帮助企业管理项目的进度、成本和质量,其作为一种使用广泛的管理方式起着重要作用。只有通过项目管理,才能更好地控制财务、人力和物力资源。项目进度管理就是在给定的资源约束和时序约束下,合理安排项目活动的顺序并进行实时监控,以达到缩短工期的优化目标。在实践中,项目进度管理在保证项目按期甚至提前完成的前提下,会影响项目的财务状况以及对资源的消耗情况。随着企业间竞争的不断加剧,项目的完成时间被要求不断缩减,再加上资源问题的日益凸显,对于资源约束项目进度问题的研究就显得尤为重要。本文在绪论部分介绍了文章的研究背景、意义、方法等内容。随后,本文对国内外学者在资源约束项目进度问题上所做的研究工作做了较为详细的梳理,并完成综述。在此基础上,本文建立了以“所有项目完工期之和最小化”和“工期最长项目的工期最小化”为目标的RCPSP模型。结合安吉物流智能调度系统的项目进度安排实例,对模型进行求解,得到不同目标的RCPSP模型的解,并比较两种模型的结果。此外,文章还讨论了不同资源数量下的资源使用率和项目完工时间问题。当资源过于充裕时,适当降低资源的数量,可以提升资源利用率,并且完工时间延迟不多。研究结论表明,资源约束项目进度问题的研究能够给项目进度管理带来一定的理论指导意义。将资源约束项目问题的求解方法应用到具体的项目进度管理中来,将会起到一定的现实意义。
[Abstract]:In the daily operation and development of the enterprise, project management can help the enterprise manage the progress, cost and quality of the project, which plays an important role as a widely used management method. Only through project management can financial, human and material resources be better controlled. Project schedule management is to arrange the sequence of project activities reasonably and monitor them in real time under the given resource constraints and timing constraints in order to achieve the optimization goal of shortening the duration of the project. In practice, the project schedule management can affect the financial situation of the project and the consumption of resources on the premise of ensuring that the project is completed on schedule or even ahead of schedule. With the aggravation of the competition among enterprises, the completion time of the project is required to be reduced continuously, and the problem of resources becomes more and more prominent, so it is very important to study the problem of resource constraint on the progress of the project. In the introduction part, this paper introduces the research background, significance, methods and so on. Then, this paper makes a detailed review of the research work done by domestic and foreign scholars on the progress of resource-constrained projects. On this basis, this paper establishes a RCPSP model which aims at "minimizing the sum of the completion periods of all projects" and "minimizing the duration of the longest project". Combining with the project schedule of Anji logistics intelligent scheduling system, the model is solved, the solutions of RCPSP model with different objectives are obtained, and the results of the two models are compared. In addition, the resource utilization rate and project completion time under different resource quantity are also discussed. When the resources are too abundant, the resource utilization can be improved by reducing the amount of the resources, and the completion time is not long. The research results show that the research of resource constrained project schedule can bring some theoretical significance to project schedule management. It will play a certain practical significance to apply the solution method of resource constrained project problem to the concrete project schedule management.
