The 21st century has seen rapid changes in technology, industry, and social patterns. Most industries have moved towards automation, and human intervention has decreased, which has led to a revolution in industries, named the fourth industrial revolution (Industry 4.0). Industry 4.0 or the fourth industrial revolution (IR 4.0) relies heavily on the Internet of Things (IoT) and wireless sensor networks (WSN). IoT and WSN are used in various control systems, including environmental monitoring, home automation, and chemical/biological attack detection. IoT devices and applications are used to process extracted data from WSN devices and transmit them to remote locations. This systematic literature review offers a wide range of information on Industry 4.0, finds research gaps, and recommends future directions. Seven research questions are addressed in this article: (i) What are the contributions of WSN in IR 4.0? (ii) What are the contributions of IoT in IR 4.0? (iii) What are the types of WSN coverage areas for IR 4.0? (iv) What are the major types of network intruders in WSN and IoT systems? (v) What are the prominent network security attacks in WSN and IoT? (vi) What are the significant issues in IoT and WSN frameworks? and (vii) What are the limitations and research gaps in the existing work? This study mainly focuses on research solutions and new techniques to automate Industry 4.0. In this research, we analyzed over 130 articles from 2014 until 2021. This paper covers several aspects of Industry 4.0, from the designing phase to security needs, from the deployment stage to the classification of the network, the difficulties, challenges, and future directions.

Servitization of manufacturing

CHANNEL PHASES: 1. Awareness: How do we raise awareness about our company’s products and services? 2. Evaluation: How do we help customers evaluate our organization’s Value Proposition? 3. Purchase: How do we allow customers to purchase specific products and services? 4. Delivery: How do we deliver a Value Proposition to customers? 5. After sales: How do we provide post-purchase customer support? Cost Structure What are the most important costs inherent in our business model? Which Key Resources are most expensive? Which Key Activities are most expensive?

The Business Model Canvas

The growth of emerging digital technologies has led to premature and inconsistent conclusions about the relationship between circular economy and value chain activities. A structured, systematic review approach was used to examine the titles and abstracts of 912 papers from the circular economy and digital transformation, strategic management, and operations management literature. We looked at a relevant selection of 79 articles to develop a research agenda. The literature review helped identify strategic initiatives impacting the firm value chain’s redesign involving logistics capabilities, marketing, sales, and service. Outcomes of this study make significant contributions to the field. First, firms must reorganize their business models that align with their value chain activities. Second, the literature review in this study adds to a growing understanding of the field of research by showing that engaging with Industry 4.0 and the circular economy is desirable and necessary for internalizing knowledge flows across different value chain actors. Third, this study is a first step in the right direction in developing and understanding the critical role of value chains and evolving business models in a global economy with calls for more sustainable development.

Designing Value Chains for Industry 4.0 and a Circular Economy: A Review of the Literature

An organisation's sustainability performance is influenced by its capabilities (skills, resources and competences) which in turn affects the performance of its entire supply chain. However, recent research has not sufficiently explored the convergence of dynamic capabilities, circular economy, resilience and Industry 4.0 concepts for manufacturing supply chains. Therefore, this study aims to identify how dynamic capabilities theory can enable circular and resilient supply chains. A qualitative research process was deployed in three stages: literature review, European project and nine expert interviews. Key investigative variables were used to identify capabilities used in manufacturing, and five research propositions were developed to address the gaps found in literature. The empirical data helped reveal challenges to circular economy implementation and validate the literature findings. The main contributions include a dynamic capabilities model, a causal relationship model and five research propositions for circular economy implementation. 

Dynamic capabilities for circular manufacturing supply chains—Exploring the role of Industry 4.0 and resilience

Industry 4.0 (I4.0) technologies have been highlighted in recent literature as enablers of servitisation. Simultaneously, businesses are advised to implement a circular economy (CE) to bring new opportunities. However, it is pertinent to mention that little attention has been given to assess the role of I4.0 in adopting the CE and servitisation in a fully integrated manner. This research fills this gap by developing a conceptual framework through a systematic literature review of 139 studies investigating the relationship between the I4.0, CE, and servitisation. This study identifies the impact of these variables on a firm’s operational and financial performance (revenue stream, growth, and profitability). Our research findings advocate that adopting I4.0 technologies to the business and manufacturing model enables sustainability, energy and resource efficiency while enhancing performance and offering innovative products through smart services. Thus, firms must systematically adopt I4.0 technologies to support a CE model that creates value through servitisation. This study identifies the research gaps that are unexplored for practitioners and future researchers while providing insight into the role of I4.0 in implementing CE in the servitisation business model.
