【摘要】：作为国民经济的基础产业,电力行业是我国经济发展战略中的重点,直接影响到社会稳定与居民生活质量。近年来,伴随着高速发展的电网建设,新建变电站工程项目越来越多。对电网建设项目的管理进行研究也逐渐成为一个热点,经过对优秀项目管理研究成果的引进、消化与分析,不少企业已经建立了具有企业自身特色的项目管理体系,但是总的来说,与国外先进水平还存在一定差异,还不能完全满足工程项目进度、成本、质量等方面的要求。如何根据预先设定的目标,按照计划工期,充分利用资源,保证成本最小的前提下尽快的完成项目成为研究重点。考虑到变电站工程具有规模庞大、组织结构复杂、投资高、影响因素众多等特点,实现对变电站工程项目合理的进度优化显得尤为重要。本文在阅读大量国内外文献的基础上,了解了有关变电站工程项目进度优化领域的研究现状以及项目进度优化的相关理论。通过对项目进度管理基本理论的学习,对项目进度控制的相关方法进行系统的梳理与归纳。针对西海500kV变电站工程项目,首先运用WBS对该工程的项目活动进行分解,在对各项活动关系和活动时间估计的基础上,绘制西海500kV变电站工程项目网络计划图和甘特图,并且估算西海500KV变电站的项目工期。然后,结合西海500kV变电站工程项目的特点,建立了进度优化模型,提出基于自适应步长的布谷鸟优化算法对其进行进度优化。研究结果表明,经过基于自适应步长的布谷鸟优化算法对西海500kV变电站工程项目进行进度优化,可以缩短工期33天,节约成本156585元,收敛速度快,波动性小。因此布谷鸟优化算法在解决变电站工程项目的进度优化问题时具有更高的有效性与适用性,为变电站工程项目的进度优化问题的解决开拓了新的思路。
[Abstract]:As the basic industry of the national economy, the electric power industry is the focal point in the economic development strategy of our country, which directly affects the social stability and the quality of life of the residents. In recent years, with the rapid development of power grid construction, more and more new substation projects. Through the introduction, digestion and analysis of the outstanding project management research results, many enterprises have established the project management system with their own characteristics. But in general, there are still some differences with foreign advanced level, which can not fully meet the project schedule, cost, quality and other requirements. How to make full use of the resources according to the pre-set target, according to the planned time limit and ensure the minimum cost to complete the project as soon as possible has become the focus of the research. Considering the large scale, complex organizational structure, high investment and numerous influencing factors, it is very important to optimize the reasonable schedule of substation project. On the basis of reading a large number of literatures at home and abroad, this paper studies the status quo of substation project schedule optimization and the relevant theories of project schedule optimization. By studying the basic theory of project schedule management, the related methods of project schedule control are systematically summarized. Aiming at the Xihai 500kV substation project, the project activities of the project are decomposed by WBS, and the network plan and Gantt diagram of Xihai 500kV substation project are drawn on the basis of estimating the activity relationship and time. And estimate the project duration of Xihai 500 KV substation. Then, according to the characteristics of Xihai 500kV substation project, the schedule optimization model is established, and the cuckoo optimization algorithm based on adaptive step size is proposed to optimize the progress of the project. The research results show that the schedule optimization of Xihai 500kV substation project based on adaptive step size Cuckoo optimization algorithm can shorten the project duration by 33 days, save the cost of 156585 yuan, fast convergence speed and low volatility. Therefore, the Cuckoo optimization algorithm is more effective and applicable in solving the optimization problem of substation project schedule, which opens up a new idea for the solution of substation project schedule optimization problem.
