【摘要】：水电是技术成熟、运行稳定的可再生能源,一直受到世界各国的高度重视,我国十二五‖能源计划更是将发展水电的任务提高到国家能源安全的战略高度。这种新的战略目标,给水电企业的发展提出了新的要求,其多项目到来呈现连续、随机、动态的特征,项目规模和复杂程度也将不断增加。因此,如何能够在满足项目物资需求的情况下尽可能实现多项目的整体目标,对物资进行合理的配置,在水电企业多项目管理中具有重要的研究意义。本文以水电企业多项目管理为研究背景,对水电企业多项目物资配置进行研究。首先,介绍论文的研究背景,分析国内外资源配置问题、多项目调度问题及考虑资源受限的物资配置问题的研究现状,提出论文的研究目的与意义,阐述论文的研究内容及章节安排。其次,结合水电企业项目多协调关系、多物资竞争以及动态性等特征,分析当前水电企业物资配置存在的问题,研究现阶段常见的物资配置方法,并分析不同物资配置方法的优缺点,找出水电企业多项目物资配置的关键问题。再次,提出一种基于时序约束和物资约束的水电企业多项目物资配置优化方法。时序约束阶段依据项目活动优先级评价模型得到项目活动合成链表,该列表即可作为无冲突情况下的多项目物资配置方案;物资约束阶段以获得的优化任务合成链表为输入,进行物资约束的检测与调整,建立冲突消解模型并用改进蚁群算法进行求解,生成项目物资配置优化方案。最后,针对H企业物资配置过程存在的问题,运用论文提出的配置方法对其进行物资配置,最终验证本论文研究的有效性与可行性。
[Abstract]:Hydropower is a renewable energy with mature technology and stable operation, which has been attached great importance to all over the world. China's 12th Five-Year Plan has raised the task of developing hydropower to the strategic level of national energy security.This new strategic goal puts forward new requirements for the development of hydropower enterprises, and its multi-project to present continuous, random, dynamic characteristics, project size and complexity will continue to increase.Therefore, how to achieve the overall goal of multi-project and reasonable allocation of materials under the condition of meeting the requirements of project materials is of great significance in the multi-project management of hydropower enterprises.Based on the multi-project management of hydropower enterprises, this paper studies the multi-project material allocation of hydropower enterprises.First of all, it introduces the research background of the paper, analyzes the domestic and foreign resource allocation problem, the multi-project scheduling problem and the research status of the resource constrained material allocation problem, and puts forward the purpose and significance of the paper.Elaborate the research content and chapter arrangement of the thesis.Secondly, according to the characteristics of multi-coordination relationship, multi-material competition and dynamic of hydropower enterprise, the paper analyzes the problems existing in the material allocation of hydropower enterprises, and studies the common material allocation methods at the present stage.The advantages and disadvantages of different material allocation methods are analyzed, and the key problems of multi-project material allocation in hydropower enterprises are found out.Thirdly, a multi-project material allocation optimization method for hydropower enterprises based on temporal constraints and material constraints is proposed.According to the project activity priority evaluation model, the time series constraint stage obtains the project activity synthesis chain list, which can be used as the multi-project material allocation scheme without conflict, and the material constraint stage takes the optimized task synthesis chain list as the input.The conflict resolution model is established and solved by improved ant colony algorithm (ACA), and the project material allocation optimization scheme is generated.Finally, aiming at the problems existing in the material allocation process of H enterprise, the method proposed in this paper is used to allocate the materials, and finally the validity and feasibility of this paper are verified.
