The Neural Network Revamping the Process’s Reliability in Deep Lean via Internet of Things

Abstract

Deep lean is a novel approach that is concerned with the profound analysis for waste’s behavior at hidden layers in manufacturing processes to enhance processes’ reliability level at the upstream. Ideal Standard Co. for bathtubs suffered from defects and cost losses in the spraying section, due to differences in the painting cover thickness due to bubbles, caused by eddies, which move toward the bathtubs through hoses. These bubbles and their movement are considered as a form of lean’s waste. The spraying liquid inside the tanks and hoses must move with uniform velocity, viscosity, pressure, feed rate and suitable Reynolds circulation values to eliminate the eddy causes. These factors are tackled through the adoption Internet of Things (IoT) technologies that are aided by neural networks (NN) when an abnormal flow rate is detected using sensor data in real-time that can reduce the defects. The NN aimed at forecasting eddies’ movement lines that carry bubbles and works on being blasted before entering the hoses through using Design of Experiment (DOE). This paper illustrates a deep lean perspective as driven by the define, measure, analysis, improvement and control (DMAIC) methodology to improve reliability. The eddy moves downstream slowly with an anti-clockwise flow for some of the optimal values for the influencing factors, whereas the circulation of Ω increases, whether for vertical or horizontal travel.

Online Fault Detection of Dry Reactor Based on Improved Kalman Filter

“…A method of fuzzy neural network is proposed, which combines fuzzy logic with neural network to construct a prediction model. BP algorithm is used to adjust the threshold and connection weight of neural network, so that the network can achieve the approximation of any function [16]. In this article, THE RBF neural network is used, weather conditions, temperature, wind speed, meteorological conditions and other factors are considered, and the RBF neural network model is established to realize load prediction.…”

“…Green investments are critical to the transition to a low-carbon economy and help react to the carbon price system's deployment. Investments should be increased to finance the transition from fossil fuels [65] to renewable energy sources, the adoption of intelligent electricity networks [66] , energy efficiency measures, and the change to the use of electricity in different sectors such as transportation, cement industry [67] , electricity generation, and construction to achieve a fundamental transformation in the current energy system. There is little question that considerable expenditures will be required throughout the transition period.…”

Industry 4.0 Application in Lean Manufacturing – A Systematic Review

“…IoT (Internet of Things) technologies such as RFID (Radio Frequency Identification) and LPWAN (Low Power Wide Area Network) are utilised to enhance digital traceability and to provide real-time information which can be effectively applied in Lean Manufacturing to identify and eliminate the waste [10][11]. IoT has also been used in integrating machines in the shop floor and also to connect to the machines with Andon systems to enhance the decision support system for process improvement [12][13].…”
