摘要:

美国的配水系统包括数千英里的管道,这些管道由不同的材料、不同的尺寸和年龄建造而成。这些管道受到物理、环境、结构和操作应力的影响,导致恶化,最终导致其失效。管道老化会导致破裂率增加、水力能力降低,并对水质产生不利影响。因此,至关重要的是使用准确的模型来预测恶化率,同时估计管道的剩余使用寿命,以实施必要的干扰计划,以防止灾难性故障。本文讨论了一种应用人工神经网络(ANN)和自适应神经模糊推理系统(ANFIS)预测水管RUL的计算模型。这些模型经过训练和测试,获得现场数据,以确定影响RUL预测的重要参数。得出的结论是,平均而言,现有铸铁、球墨铸铁、石棉水泥和钢水管的壁厚损失约为10%,剩余使用寿命约减少50%

英文摘要:

The U.S. water distribution system contains thousands of miles of pipes constructed from different materials, and of various sizes, and age. These pipes suffer from physical, environmental, structural and operational stresses, causing deterioration which eventually leads to their failure. Pipe deterioration results in increased break rates, reduced hydraulic capacity, and detrimental impacts on water quality. Therefore, it is crucial to use accurate models to forecast deterioration rates along with estimating the remaining useful life of the pipes to implement essential interference plans in order to prevent catastrophic failures. This paper discusses a computational model that forecasts the RUL of water pipes by applying Artificial Neural Networks (ANNs) as well as Adaptive Neural Fuzzy Inference System (ANFIS). These models are trained and tested acquired field data to identify the significant parameters that impact the prediction of RUL. It is concluded that, on average, with approximately 10\% of wall thickness loss in existing cast iron, ductile iron, asbestos-cement, and steel water pipes, the reduction of the remaining useful life is approximately 50%
