Problems solved by technology

However, due to the lack of theoretical basis, the current research in this field is still in the exploratory stage. In practice, the zoning planning is usually completed based on engineering experience, which is not only time-consuming and laborious, but also difficult to guarantee the reliability of the zoning scheme.
These factors directly hinder the promotion of zoning transformation, making some modern management needs based on zoning transformation unable to be met

Embodiment Construction

[0020] The specific steps of the water supply pipe network partitioning method based on topology evolution of the present invention will be further described below in conjunction with the accompanying drawings.

[0021] (1) Determine the number of districts according to the economic level index; the economic level index is formulated by the decision-making level of the water supply group;

[0022] (2) Use an undirected graph to represent the topology of the pipe network: Unlike the hydraulic model, the undirected graph only needs to contain uniform types of nodes and edges without distinguishing between component types and attributes, that is, all point components in the model are are nodes, and linear components are used as edges, and the connection relationship between nodes and edges is the topology of the pipe network;

[0023] (3) Topological analysis to determine the boundaries of partitions: use complex network community structure analysis methods to analyze the topolog...

Abstract

The invention relates to a water supply pipeline network partitioning method based on topology structure evolution, belonging to the management field of municipal works. In a method framework, a water supply pipeline network is regarded as a specific complex system, the topology structure is firstly abstracted out as an analysis object for determining a community structure formed during pipeline network evolution; secondly partitioning planning is performed according to an economic level goal made by an administrator based on community structure division, so as to generate a scheme; finally all schemes are optimized and the most economic scheme is determined under a condition that the water supply security is met. According to the invention, a scientific partitioning method which can be used as a theory basis is provided for the first time, and the method is easy and rapid to operate, thus having significant application value for partitioning planning practice and research in the future.

Description

technical field [0001] The invention relates to a planning method for a water supply pipe network partition management mode, in particular to a water supply pipe network partition method based on topological structure evolution, and belongs to the field of municipal engineering management. Background technique [0002] Zoning management is an important means to essentially improve the problems faced in the traditional water supply network management, such as leakage control. However, due to the lack of theoretical basis, the current research in this field is still in the exploratory stage. In practice, the zoning planning is usually completed based on engineering experience, which is not only time-consuming and laborious, but also difficult to guarantee the reliability of the zoning scheme. These factors directly hinder the promotion of zoning transformation, making some modern management needs based on zoning transformation unable to be met. Contents of the invention [...
