Preface
The Fourth Industrial Revolution, also known as Industry 4.0 or I4.0, refers to the recent accelerated uptake of a portfolio of technologies that enable a high degree of automation, integration, transparency, decentralization, and at the same time interconnectedness in the industrial sector, as well as other sectors such as health, education, and agriculture, enabling optimal and evidence-based decision-making. The emergence of Industry 4.0 is the result of dramatic advances and convergence in multiple disciplines. These include a sharp increase in the capabilities for artificial intelligence, wireless communication (e.g., Internet of things), cloud-based computations, smart transactions (blockchains), and robotics. Such capabilities have manifested themselves in the form of novel paradigms such as smart manufacturing, the Internet of things, predictive maintenance, and additive manufacturing.
The present contribution reports the collective endeavors of a multidisciplinary group of researchers to explore the emerging trends inspired by the aforementioned evolutions, especially with the focus on the flow of energy and materials in supply chains. The book has two main parts. In the first part, the key drivers of Industry 4.0, namely, artificial intelligence, wireless communication, blockchains and smart contracts, cloud computing, and robotics, are discussed. The second part explores the application of such advancements in the fields of energy networks, additive manufacturing, pharmaceutical industry, water distribution, renewable power generation, petroleum and gas industries, as discussed in the following.
Chapter 1 explores recent advancements in sensor and communication technologies and their contribution to the realization and commercial viability of industrial/Internet of things (I/IoTs), smart manufacturing, and other Industry 4.0 paradigms. It also discusses the applications of communication technologies in Industry 4.0 and the required criteria. Other features of interest include the relevant standards and protocols, cellular and mobile technologies, the design of wireless systems for IIoT applications and relevant protocols, and smart sensors and their enabling role in Industry 4.0. The chapter concludes with predicting future trends in wireless communication for Industry 4.0.
Chapter 2 explores the concepts and methods that have enabled distributed and smart transaction systems such as blockchains. The features of interest include the blockchain taxonomy, desirable attributes, architecture, and most importantly the emerging applications in different sectors.
Chapter 3 is concerned with the application of robotics in Industry 4.0. First, a comprehensive survey of various classes of robots is presented. The classification is presented with respect to robots’ geometry, actuator and control strategies, and kinematics, as well as more advanced features such as the number of agents and fabrication materials. Then the applications of various robotic systems are presented in different areas.
Chapter 4 focuses on the utilization of cloud computing in Industry 4.0. The main characteristics of cloud computing, as well as developed architectures and types of services, the model of cloud deployment, and the corresponding pros and cons are extensively discussed in this chapter. The last part of this chapter explores emerging paradigms such as edge computing and fog computing and elucidate their differences compared with traditional cloud and grid computing.
Chapter 5 provides a comprehensive review of artificial intelligence (AI) methods. The reviewed algorithms are categorized into supervised and unsupervised methods. In the supervised methods, two major groups of classification and regression methods are discussed. In the classification methods, the key features of decision trees (DT), the (naive) Bayesian classifier, K-nearest neighbors (KNNs), linear discriminant analysis (LDA), support vector machines (SVM) and kernel methods, relevance vector machines (RVMs), ensemble methods, and logistic regression are reviewed. In the regression methods, ordinary least squares (OLS) regression, ridge and lasso regression, support vector regression (SVR), Gaussian process regression (GPR), and thin plate spline (TPS) are discussed. A separate section is devoted to neural networks and deep learning, especially to recent developments in convolutional neural networks (CNNs), recurrent neural networks (RNNs), long short-term memory (LSTM), transformers, graph neural networks (GNNs), generative adversarial networks (GAN), autoencoders, and self-organizing maps (SOMs). Among unsupervised learning algorithms, special attention is paid to clustering methods such as k-means clustering and hierarchical clustering, DBSCAN, as well as linear and nonlinear dimensionality reduction methods (e.g., principal component analysis [PCA], linear discriminant analysis, manifold learning, Laplacian eigenmaps method). This chapter also provides a brief overview of semi-supervised and active Learning, bio-inspired methods, as well as reinforcement learning (RL).
The second part of the book begins with Chapter 6, in which the concept of the Internet of energy (IoE) is introduced. The discussion starts with the description of conventional energy grids, exposure of their limitations, and elucidation of the potentials that have become available through the incorporation of the Industry 4.0 technologies. It continues by reviewing the structure of IoE, with particular emphasis on energy routers, energy hubs, and software-defined networks (SDNs). The utilization of other I4.0 technologies such as big-data analytics and blockchains are also discussed with a special focus on energy trading and transactive IoE.
In Chapter 7, a more specific problem relevant to the Internet of energy is evaluated, which is concerned with the evolving nature of energy infrastructures. Considering the depleting fossil sources and their negative environmental impact, significant efforts are devoted to commercial utilization of renewable energies such as wind and solar power generation. However, the high penetration of renewable energies in the electricity grid also poses a significant challenge due to the intermittent and stochastic nature of wind and solar energies. The conventional approach to tackle such complexity is either through
