Comparison of Fuzzy logic and Neural Network in life prediction of boiler tubes

Prognostic modelling options for remaining useful life estimation by industry

“…Again, data was acquired from accelerated bearing tests rather than field data. Results by Majidian confirmed the suitability of MLPs with backpropagation learning for predicting the life of tubes in a power boiler; however, it was very sensitive to the number of nodes in the hidden layer [21].…”

“…Yet although fuzzy logic is regularly used to enhance other types of prognostic models [17][18][19][20], there are few examples of where it has been used as the primary method for RUL prediction. Majidian and Saidi [21] used fuzzy logic to predict the life of a set of boiler tubes, as per a behavioural model, and results compared favourably with those from a neural network, although the authors noted that the neural network was easier to develop than the fuzzy system. In devising a method for estimating the remaining life in rechargeable military batteries, Shimanek applied a combination of autoregressive moving average, neural networks and fuzzy logic algorithms [22].…”

“…Common architectures include the Multi-layer Perceptron (MLP), Radial Basis Function (RBF) network and General Regression Neural Network (GRNN). Most prognostic RUL models developed to date have been based on these static networks, with the multilayer perceptron being the most popular architecture [21,[136][137][138][139][140][141] (using various different activation functions). RBF networks are faster to train but require some knowledge of the specific application as they use fixed weights in the hidden layer [142].…”

Analysis of Boiler Operational Variables Prior to Tube Leakage Fault by Artificial Intelligent System

“…Fast and Palméb [2] applied ANN for condition monitoring and diagnosis of a combined heat power (CHP) plant by an online monitoring system. Majidian [3] compared results of Fuzzy logic and Neural Network (NN) in life prediction of boiler tubes. Wall thickness of re-heater tubes of boiler of Neka power plant in north of Iran were measured during maintenance shutdown period.…”

Using decision trees in economizer repair decision making

“…Due to the abrasive nature of the hot, grit-filled exhaust gases, economiser tubing systems suffer from erosion which often results in tubes leaking [2]. Economiser tube failures account for about 10% of all boiler tube failures [3].…”
