【摘要】：成本控制和质量控制是工程建设项目的重要管理内容和必须要考虑的因素。在工程项目管理中,对成本和质量进行全面系统地分析和综合均衡优化,再对项目方案做出决策,对于提高工程建设项目的综合效益具有很重要的意义。本论文基于各地配电网改造项目管理中主要存在的问题,综合考虑电气设备的投资成本和质量,提出项目管理的多目标决策。论文首先介绍了配电网改造项目管理中的投资决策以及全寿命周期成本(LCC)理论的应用,建立并比较了成本管理中投资决策的净现值法(NPV)、内涵报酬率法(IRR)和现值指数法(PI)三种模型,考虑了不同条件下的三种模型的选择；其次利用基于层次分析法(AHP)的多目标决策理论,将成本管理与质量管理结合起来,建立了配网改造项目中成本与质量多目标决策的三层模型,利用各方案分别形成的3个n*n阶判断矩阵,计算各矩阵的权重向量,取权重最大的方法为最终决策方案；最后建立基于LCC的配网设备投资费用构成模型,包括设备投资费用、运行维护费用、设备残值以及其他费用,并对各费用进行折现计算,形成最终的电力设备LCC费用计算模型。论文选取了一个实际的配网改造项目,提出两种改造方案,采用论文中提到的理论方法对实际配网改造项目进行决策,先依次计算出两种方案的LCC费用构成与负载收益。再根据此结果计算出两方案的投资回收期以及净现值,作为对于两方案决策的参考指标。最后基于多目标投资决策的理论,利用层次分析法对两种改造方案进行选取。最后的结果验证了模型的有效性和正确性。
[Abstract]:Cost control and quality control are important management contents and factors that must be considered in engineering construction projects. In engineering project management, the cost and quality are comprehensively and systematically analyzed and integrated balanced optimization. It is very important to make decision on the project scheme to improve the comprehensive benefit of the project. This paper is based on the main problems in the management of distribution network transformation project. Considering the investment cost and quality of electrical equipment, the multi-objective decision of project management is put forward. Firstly, the paper introduces the investment decision and the application of LCCtheory in distribution network renovation project management, and establishes and compares the NPV (net present value method) of investment decision in cost management. There are three models, IRR and PI), which consider the choice of three models under different conditions. Secondly, by using the multi-objective decision theory based on Analytic hierarchy process (AHP), combining cost management with quality management, the three-layer model of cost and quality multi-objective decision-making in distribution network reconstruction project is established. The weight vectors of each matrix are calculated by using three nnnth order judgment matrices formed by each scheme, and the method with the largest weight is taken as the final decision plan. Finally, the investment cost model of distribution network equipment based on LCC is established, including equipment investment cost, operation and maintenance cost, equipment residual value and other expenses, and the discounted cost is calculated. The final LCC cost calculation model of power equipment is formed. This paper selects an actual distribution network transformation project, puts forward two transformation schemes, and uses the theoretical method mentioned in the paper to make a decision on the actual distribution network transformation project. First, the LCC cost structure and load income of the two schemes are calculated in turn, and then the investment recovery period and the net present value of the two schemes are calculated according to the results. Finally, based on the theory of multi-objective investment decision, the AHP is used to select the two modification schemes. Finally, the validity and correctness of the model are verified.
