Abstract

The invention discloses a water supply pipe network modeling method based on a BRB system. The invention firstly collects the historical data of pipe network operation, secondly determines the input variables and output variables of the water supply pipe network model, then establishes the BRB-based water supply pipe network model, and finally establishes the BRB-based water supply pipe network MIMO model. The invention can well describe the working condition of the water supply pipe network system, and can be compared with the neural network model of the water supply pipe network when used for the real-time optimal scheduling of the water supply pipe network. Moreover, by analyzing the rule base trained by the historical operation data of the pipe network, the unknown characteristics of the water supply pipe network can be further mined.

Description

technical field [0001] The invention belongs to the field of urban water supply, in particular to a water supply pipe network modeling method based on a BRB (Belief-Rule-Base) system. Background technique [0002] The urban water supply network system is a network structure with complex topology, large scale, strong randomness of water use changes, a large number of uncertain parameters, and multi-objective operation control. Establishing a working condition model that matches the characteristics of the pipe network system is a prerequisite for realizing the optimal operation of the water supply pipe network. Establishing a water supply pipe network model that can simultaneously deal with the uncertainty of pipe network parameters, quantitative and qualitative information is the key to analyzing and evaluating the safety of the pipe network. prerequisites for reliability and reliability. Scholars at home and abroad have done a lot of research on water supply network modelin...
