An I4.0 Review on Lean Green and Six Sigma Based on Energy Parameter

There is a corresponding and complementary relationship among the three manufacturing techniques/processes—lean, green, and six-sigma—in premise of Industry 4.0. The three manufacturing techniques assist the managers for big data analysis of industrial wastes/byproducts and its corresponding influences over industries. The practiced manufacturing techniques are functioning for managing and controlling wastes, operations, and quality of product, respectively. It is perceived that lean especially focus is to recognize the several wastes, produced by miscellaneous organizational practices in premise of Industry 4.0. On the other hand, green assists the managers to map the environmental practices/consequences. The present research focuses attention on ‘greening' through life cycle assessment to fill this gap and to assess the environmental impacts of the generated waste. Nevertheless, lean and green when conjoined become enabling to identify the waste and evaluate environmental impact but both encompass no motive to reduce the enhanced quality of product and reducing micro level wastes. Six-sigma is exhibited as the preeminent methods in order to overcome the determined gaps in present research work.
