SNA-based power distribution network construction cost management and control index research method and system

Abstract

The invention relates to an SNA-based power distribution network construction cost management and control index research method and system. The method comprises the following steps of 1, collecting construction cost management and control index data of a power distribution network engineering project; 2, performing data preprocessing on the construction cost management and control indexes, and constructing a construction cost management and control index system required by an SNA algorithm according to actual conditions; and step 3, using an SNA algorithm to diagnose the construction cost management and control indexes which are easy to generate deviations. And 4, analyzing the calculated result to obtain the construction cost key management and control index of the power distribution network engineering project. According to the method, the importance degree of the key management and control indexes and the mutual relation between the key management and control indexes can be better found. A built power distribution network construction cost management and control index system is supplemented and upgraded, the management and control key degree of the index is reasonably distributed, and the defects of a previous system are corrected. And reference is provided for establishment and operation of a power distribution network construction cost management and control index system in the future.

Description

technical field [0001] The invention relates to the field of whole-process management and control of distribution network construction, in particular to a research method and system for distribution network construction cost control indicators based on SNA. Background technique [0002] The existing social network analysis (SNA) is a research branch gradually developed in the fields of sociology, psychology, anthropology, mathematics, and communication science since the 1970s. It is not just a tool, but a relational way of thinking. Some domestic scholars in the field of information science have used social network analysis methods to carry out a series of research on competitive intelligence, knowledge management, library resource allocation, subject hotspots, citation analysis, co-authorship of researchers, network links, and blog networks. The application of this method in the cost control of distribution network engineering construction has not yet started. At present,...

Problems solved by technology

[0034] The calculation of the fault tree analysis process is quite heavy and complicated, and the difficulty is relatively high, and the requirements for analysts are also high. When constructing a fault tree, logic operations must be used, and the entire state space needs to be exhausted, which is not fully grasped by ordinary analysts. error and oversight are prone to occur
