【摘要】：隨著信息時代的各種技術(shù)的發(fā)展,傳統(tǒng)的工程項目管理方法已不再適合新時代的需求。運用計算機技術(shù)實現(xiàn)和推進工程項目流程管理的優(yōu)化,改善傳統(tǒng)的管理方式,對于提高送變電工程管理水平和效率具有極強重大的意義。傳統(tǒng)的送變電工程項目主要是通過紙質(zhì)文檔和現(xiàn)場照片的形式,對項目進行管理和進度分析。然而,送變電工程項目涉及專業(yè)面廣、管理流程復(fù)雜,使得其管理的文檔和現(xiàn)場照片數(shù)量眾多,而且由人工的方式維護施工流程和各種文件的對應(yīng)關(guān)系,工作量非常巨大,導(dǎo)致難以全面、及時的分析和把握施工進度。為了解決這一問題,論文設(shè)計并實現(xiàn)了一個高效、可行的送變電工程項目管理軟件系統(tǒng)。同時,考慮到施工過程中,存在多個施工現(xiàn)場大量文件和照片隨機并發(fā)上傳、下載的情況,在系統(tǒng)的架構(gòu)設(shè)計中引入分布式架構(gòu)。在對傳統(tǒng)的負(fù)載平衡算法進行了深入研究的基礎(chǔ)上,結(jié)合工程項目文件管理的需求,對傳統(tǒng)的負(fù)載平衡算法進行了改進和優(yōu)化,最后將基于負(fù)載平衡的文檔優(yōu)化管理算法應(yīng)用于系統(tǒng)的分布式文件系統(tǒng)上,保證了系統(tǒng)的負(fù)載平衡。論文主要完成了以下工作:(1)對送變電工程管理方法及管理系統(tǒng)的相關(guān)技術(shù)進行了現(xiàn)狀分析。對傳統(tǒng)的送變電工程項目管理系統(tǒng)存在的問題、發(fā)展的關(guān)鍵技術(shù)及難點進行了分析和研究;(2)對送變電工程項目管理軟件系統(tǒng)的需求、性能指標(biāo)進行了分析,然后根據(jù)系統(tǒng)特點,設(shè)計了由界面交互層、項目管理模塊、分布式文件系統(tǒng)、數(shù)據(jù)層組成的系統(tǒng)結(jié)構(gòu);(3)對送變電工程項目管理的特點和工程管理流程進行了分析,在此基礎(chǔ)上,對施工流程進行了建模,并設(shè)計了相應(yīng)的流程模型管理模塊。詳細(xì)設(shè)計了工程項目創(chuàng)建、施工月報管理以及項目進度查詢等模塊;(4)對傳統(tǒng)的負(fù)載平衡算法進行了深入的研究,并在研究基礎(chǔ)上,從結(jié)點負(fù)載量計算方法、負(fù)載平衡閾值策略、負(fù)載遷移策略三個方面對算法進行了改進,并將改進算法與傳統(tǒng)的負(fù)載平衡算法進行了對比仿真;(5)設(shè)計并實現(xiàn)了送變電工程項目管理軟件系統(tǒng),從系統(tǒng)功能和改進算法負(fù)載平衡效果兩個方面設(shè)計并進行了相關(guān)測試。通過對本文所設(shè)計并實現(xiàn)的送變電工程管理系統(tǒng)的測試,該系統(tǒng)通過工程中各階段文檔齊全性檢測機制,強化了工程管理質(zhì)量、工期過程管控。
[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.
