Integrating lean manufacturing in industry 4.0 drives smart manufacturing, facilitating manufacturers' efforts to increase output from existing production capacities and develop the next generation of production capabilities needed to compete in the digital economy.
FREMONT, CA: Lean manufacturing (LM) is a set of management techniques and principles designed to eliminate waste and simplify activities adding value to products from a customer perspective. By optimising process steps and reducing waste, only beneficial value is added at each production stage. LM principles are applied across industries, and these tools are recognised worldwide as a successful operational framework for alleviating waste, increasing productivity, and continuously improving organisations.

Industry 4.0 allows companies to enhance their current manufacturing operations and practices to a more advanced level by leveraging emerging technologies. With the evolution of the global market, manufacturing systems become smarter, more flexible, digital, and agile and can keep pace with market volatility. Industry 4.0 drives smart manufacturing, allowing manufacturers to increase output from existing production capacities and develop next-generation production capabilities essential to competing in the digital economy.
Manufacturers worldwide experience drastic changes by leveraging industry 4.0 technologies like cloud computing, big data analytics, robotics, and the Internet of Things (IoT). Industry 4.0 technologies have a significant impact on the sustainability performance of the manufacturing industry as they create better machines, improve communication and working conditions, and improve product quality. IoT, sensors, and big data can enhance the environmental, social, and economic aspects of the plastics industry. Through digitization, Industry 4.0 technologies can reduce production and transportation costs and lead times, thereby elevating customer satisfaction and an organisation’s profit.
In terms of the environmental aspect, data sharing among supply chain stakeholders and the availability of real-time data enable the efficient allocation of raw materials, water, energy, and labour, reducing resource consumption and waste generation. As a social concept, industry 4.0 provides people with new technologies to improve motivation and morale by offering safe working conditions.
The importance of pairing LM with Industry 4.0 is gaining momentum. Organisations will greatly benefit from industry 4.0 technologies and LM together. Integrating LM into Industry 4.0 requires more research, although it is regarded as an enabler of Industry 4.0 for its introduction. Their combination can reduce waste and cost in fields where LM alone is not feasible. In addition, industry 4.0 technologies are more expensive to implement without LM principles; therefore, further integration of them will reduce implementation costs. Companies can benefit from new innovative and automated manufacturing techniques or lean digital transformation. Furthermore, there is a need for a smart and sustainable manufacturing system (SSMS) with dynamic Lean 4.0 tools as the outputs of synergistic relationships for optimised production processes.
