Introduction

I. INTRODUCTION TO 4.0

The 18th century marked the advent of mechanical machines, initiating the first industrial revolution. The second industrial revolution emerged in the early 20th century with the introduction of electricity and mass production. In the early 1970s, the third industrial revolution commenced with the arrival of electronics and Information Technology (IT), leading to the automation of manufacturing processes and the use of programmed machines to handle production responsibilities.

To remain competitive against emerging nations like India and China and provide greater value to customers, developed countries began implementing advanced technologies at the production level. In the United States and other countries, these efforts are referred to as the fourth industrial revolution, Internet of Things (IoT), or next-generation systems. Meanwhile, Germany has taken the lead in this initiative, driven by the German government (Bundesministerium für Bildung und Forschung), and it is known as Industry 4.0 (industrie 4.0) (MacDougall, 2014). Figure 1 depicts the progression of industrial revolutions.

Industry 4.0 represents the contemporary wave of automation technologies employed in the manufacturing sector (Gulati, K., Nayak K. M.., Priya, B, S. Venkatesh, B, Satyam, Y.& Chahal D (2022). It encompasses cyber-physical systems, cloud computing, and IoT technologies to facilitate efficient information exchange among various departments within manufacturing companies, thereby optimizing production processes. Industry 4.0 plays a crucial role in establishing smart factories.

Put simply, Industry 4.0 refers to the digital transformation of manufacturing operations, including production, information sharing, and value creation processes. At the core of Industry 4.0 are cyber-physical systems, such as smart machines, which serve as control systems for monitoring various business activities in manufacturing and value creation (Rohatgi, S., Gera, N. & Nayak, K.(2023). Embedded software systems and IoT-based technologies are utilized to facilitate information sharing, making it easier to optimize resource management and enable innovative production methods.

From a governmental perspective, big data presents its own set of challenges. Governments must balance the need to safeguard citizens' privacy while businesses seek to extract customer data for marketing assistance. This raises concerns among users of systems that intrude upon their privacy and access personal information. (M. Rajagopal, K. M. Nayak, K. Balasubramanian, I. Abdul Karim Shaikh, S. Adhav, and M. Gupta, "Application of Artificial Intelligence in the Supply Chain Finance," 2023)

The study conducted by K. M. Nayak, P. Kiran Kumar Reddy, S. Priya, T. Srinidhi, G. Poornima, and M. Gupta in "Content Features and Machine Learning Based Effective Fake News Detection" (2023) highlights certain challenges concerning digital skills training from both employers and employees' perspectives. Employers tend to prioritize hiring already skilled workers rather than investing in training the existing workforce, as this is considered a more cost-effective and efficient approach.

According to the research by P. K. Lakineni, K. M. Nayak, H. Pallathadka, K. Gulati, K. Pandey, and P. J. Patel in "Fraud Detection in Credit Card Data using Unsupervised & Supervised Machine Learning-Based Algorithms" (2022), the primary focus of improvement lies in the communication layer to enhance the quality and efficiency of data transfer. However, these modifications and updates require substantial capital investment. Without governments updating the essential communication infrastructure, companies may find it challenging to implement industry 4.0 techniques.

As stated by Nayak K and Shah B in their work (2017), Industry 4.0 is not anticipated to replace the existing workforce. Instead, it is expected to reshape the job market and lead to a segregation of roles and responsibilities.

In the context of the study by P. Nigam, Nayak K, and Vyas P in "E-Commerce Challenges: A Case Study of Flipkart.com Versus Amazon" (published in the INDIAN JOURNAL OF APPLIED RESEARCH, 5(2), pp. 332-333), companies like Amazon Fresh and Whole Foods utilize data analytics to identify products that require innovation and development to meet the ever-changing expectations of their customers. Similar to businesses, governments also prioritize the maintenance of quality products. This commitment to product quality directly influences the export of goods, as previously discussed, leading to a positive impact on the economy (Raythatha P, Nayak K in "A Case Study on e-Business of Online Travel Agent cleartrip.com," published in GLOBAL JOURNAL FOR RESEARCH ANALYSIS, 4(3), pp. 1-2).

Maintaining quality is crucial for firms for various reasons. One significant benefit is that it results in reduced rejection rates, which, in the long term, translates to cost savings for the company (Nayak K, Bhatt V, Nagvadia J in "Measuring Impact of Factors Influencing Consumer Buying Intention with Respect to Online Shopping," published in International Journal of Management (IJM), 12(1), pp. 230-242).

According to Cisco's estimate in 2015, the number of IoT devices is projected to reach around 50 billion by 2020. This substantial number of connected devices opens up new opportunities and possibilities across various fields. Industries and academia will discover novel use cases and services that can be offered to different sectors.

Currently, the utilization of IoT in production-level use cases is limited, and organizations are unsure of how to fully leverage its potential. However, collaboration is expected to gain more emphasis in the future, particularly from an Industry 4.0 standpoint, as highlighted in the report by Meghna Aggarwal, Keyurkumar M Nayak & Viral Bhatt (2023).
