SUPPLY CHAIN OPTIMIZATION IN MANUFACTURING INDUSTRY THROUGH LEAN MANUFACTURING IMPLEMENTATION

Abstract

The supply chain plays a crucial role in the manufacturing industry, where efficiency and speed of distribution are the main factors in increasing a company's competitiveness. However, various challenges such as operational inefficiencies, waste, and delays in production often hinder supply chain performance. Lean Manufacturing is present as an effective solution for optimizing the supply chain by reducing waste, increasing efficiency, and speeding up production and delivery cycle times. This research uses a systematic literature review (SLR) method to analyze the application of Lean Manufacturing in various manufacturing sectors, such as automotive, electronics, food and beverages, and textiles. Data was obtained from scientific journals, books and relevant industry reports, then analyzed using the PRISMA method and a thematic approach to identify main trends, benefits and challenges in Lean implementation. The research results show that Lean Manufacturing can significantly increase supply chain efficiency by eliminating waste, increasing productivity, and improving coordination between stakeholders in the supply chain. However, challenges such as organizational cultural resistance, difficulties in technology integration, and limited resources and expertise are still obstacles in implementing Lean as a whole. In conclusion, Lean Manufacturing has a strategic role in optimizing the supply chain in the manufacturing industry. With proper integration and the support of modern technology, companies can increase their competitiveness and create a supply chain that is more adaptive, efficient and responsive to global market dynamics.
