Abstract

The hydraulic analysis of water distribution networks (WDNs) is crucial for ensuring efficient management of water resources, a key aspect of sustainable urban development. Formulation and steady-state hydraulic analysis of these networks have been conducted using both numerical and non-numerical methods. WDN hydraulic equations are complex and non-linear, requiring multiple executions, making their hydraulic analysis computationally demanding and energy intensive. This paper introduces an energy-efficient parallel computing approach using learning automata to significantly enhance the speed and energy efficiency of hydraulic analysis. By employing a cellular automaton framework that reflects the WDN structure, and a solution methodology based on the Taylor series enhanced with learning automata, we propose a system that reduces computational time and energy consumption. We compare the performance of our proposed approach with the EPANET software across networks of varying complexity and topologies. The results suggest our parallel algorithm not only accelerate the hydraulic analysis process up to 60 times compared to existing methods, but also significantly decrease the energy consumption, highlighting its potential for sustainable water management practices.
基于学习自动机的配水管网节能水力分析并行计算方法
供水管网的水力分析对于确保水资源的有效管理至关重要,水资源管理是可持续城市发展的一个关键方面。采用数值方法和非数值方法对这些管网进行了计算和稳态水力分析。WDN水力方程是复杂的、非线性的,需要多次执行,这使得它们的水力分析计算要求高,能耗大。本文介绍了一种利用学习自动机的节能并行计算方法,大大提高了水力分析的速度和能效。通过采用反映WDN结构的元胞自动机框架和基于学习自动机增强的泰勒级数的解决方法,我们提出了一个减少计算时间和能量消耗的系统。我们将我们提出的方法与EPANET软件在不同复杂性和拓扑网络中的性能进行了比较。结果表明,与现有方法相比,我们的并行算法不仅将水力分析过程加快了60倍,而且显著降低了能耗,突出了其可持续水管理实践的潜力。
