【摘要】：随着信息时代的各种技术的发展,传统的工程项目管理方法已不再适合新时代的需求。运用计算机技术实现和推进工程项目流程管理的优化,改善传统的管理方式,对于提高送变电工程管理水平和效率具有极强重大的意义。传统的送变电工程项目主要是通过纸质文档和现场照片的形式,对项目进行管理和进度分析。然而,送变电工程项目涉及专业面广、管理流程复杂,使得其管理的文档和现场照片数量众多,而且由人工的方式维护施工流程和各种文件的对应关系,工作量非常巨大,导致难以全面、及时的分析和把握施工进度。为了解决这一问题,论文设计并实现了一个高效、可行的送变电工程项目管理软件系统。同时,考虑到施工过程中,存在多个施工现场大量文件和照片随机并发上传、下载的情况,在系统的架构设计中引入分布式架构。在对传统的负载平衡算法进行了深入研究的基础上,结合工程项目文件管理的需求,对传统的负载平衡算法进行了改进和优化,最后将基于负载平衡的文档优化管理算法应用于系统的分布式文件系统上,保证了系统的负载平衡。论文主要完成了以下工作:(1)对送变电工程管理方法及管理系统的相关技术进行了现状分析。对传统的送变电工程项目管理系统存在的问题、发展的关键技术及难点进行了分析和研究;(2)对送变电工程项目管理软件系统的需求、性能指标进行了分析,然后根据系统特点,设计了由界面交互层、项目管理模块、分布式文件系统、数据层组成的系统结构;(3)对送变电工程项目管理的特点和工程管理流程进行了分析,在此基础上,对施工流程进行了建模,并设计了相应的流程模型管理模块。详细设计了工程项目创建、施工月报管理以及项目进度查询等模块;(4)对传统的负载平衡算法进行了深入的研究,并在研究基础上,从结点负载量计算方法、负载平衡阈值策略、负载迁移策略三个方面对算法进行了改进,并将改进算法与传统的负载平衡算法进行了对比仿真;(5)设计并实现了送变电工程项目管理软件系统,从系统功能和改进算法负载平衡效果两个方面设计并进行了相关测试。通过对本文所设计并实现的送变电工程管理系统的测试,该系统通过工程中各阶段文档齐全性检测机制,强化了工程管理质量、工期过程管控。
[Abstract]:With the development of various technologies in the information age, the traditional engineering project management methods are no longer suitable for the needs of the new era. The application of computer technology to realize and promote the optimization of engineering project flow management and to improve the traditional management mode are of great significance for improving the management level and efficiency of power transmission and transformation projects. The traditional power transmission project is mainly through the form of paper documents and field photos to manage and analyze the progress of the project. However, the power transmission project involves a wide range of professional, complex management process, which makes the number of documents and field photos to be large, and the corresponding relationship between construction process and all kinds of documents is maintained by manual way, the workload is very huge. It is difficult to analyze and grasp the construction progress in a comprehensive and timely manner. In order to solve this problem, an efficient and feasible project management software system is designed and implemented. At the same time, considering that there are a lot of files and photos uploaded and downloaded randomly in the construction process, the distributed architecture is introduced into the architecture design of the system. Based on the deep research of the traditional load balancing algorithm and the requirement of project file management, the traditional load balancing algorithm is improved and optimized. Finally, the optimal document management algorithm based on load balancing is applied to the distributed file system, which ensures the load balance of the system. The main work of this paper is as follows: (1) the current situation of power transmission project management method and management system is analyzed. The problems, key technologies and difficulties of the traditional power transmission project management system are analyzed and studied. (2) the requirement and performance index of power transmission project management software system are analyzed, and the system structure composed of interface interaction layer, project management module, distributed file system and data layer is designed according to the characteristics of the system. (3) the characteristics of power transmission project management and the engineering management flow are analyzed. On this basis, the construction process is modeled and the corresponding process model management module is designed. Detailed design of the project establishment, construction monthly report management and project progress query module; (4) the traditional load balancing algorithm is deeply studied, and on the basis of the research, the algorithm is improved from three aspects: node load calculation method, load balance threshold strategy, load transfer strategy. The improved algorithm is compared with the traditional load balancing algorithm. (5) the project management software system of power transmission project is designed and implemented. The system function and the load balance effect of the improved algorithm are designed and tested. Through the test of the power transmission and transformation project management system designed and implemented in this paper, the system strengthens the quality of project management and the control of the duration of the project through the mechanism of detecting the completeness of documents in each stage of the project.
