Redesigning of Smart Manufacturing System Based on IoT: Perspective of Disruptive Innovations of Industry 4.0 Paradigm

Context: Manufacturing plants are working with limited efficiency and productivity. Manufacturing plants can become more efficient, productive and smarter by adopting the enabling technologies of Industry 4.0. In this research paper, effort is made to explore the impact of IoT in assembly line of small scale transformer manufacturing industry. Purpose: Purpose of this research paper is to use IoT based framework in assembly line of small scale transformer manufacturing industry located in Mumbai, India to illustrate the effect on efficiency, productivity, and safety. Methodology: In this research paper, keyword based literature review is carried out. Based on the review, IoT framework is used in assembly line of small scale transformer manufacturing industry. Finally, reliability and effectiveness of IoT framework is determined by performing paired t-test hypothesis testing and Value Stream Mapping (VSM). Findings: Impact of IoT framework on the assembly line of small scale transformer manufacturing industry is described and dramatic changes are observed. Impact on Technology: IoT framework for assembly line of small scale transformer manufacturing industry has capability to optimize parameters such as cycle time, rejection rate, and productivity. Impact on society and environment: IoT based smart system reduces fatigue and stress of workers by reducing rejection rate and search time in the assembly line. Reduction in rejection rate decreases energy consumption in assembly line which reduces the energy problem of society. Limitations of proposed research work: This research has been performed by considering only the assembly line. However, other manufacturing processes of small scale transformer manufacturing industry can also be improved by implementing developed IoT framework.
