Abstract


This article highlights the Lean manufacturing; which is a variation on the theme of &sec=article&uinfo=<%=server.URLEncode(2096)%>" title=Efficiency>efficiency based on optimizing flow; it is a present-day instance of the recurring theme in human history towards increasing efficiency, decreasing waste, and using empirical methods to decide what matters, rather than uncritically accepting pre-existing ideas. It is an article deals with the Lean manufacturing tools and techniques. The implementing lean manufacturing in India and its benefits are discussed.

Concept of Lean Manufacturing:


Lean Manufacturing is "A systematic approach to identifying and eliminating waste through continuous improvement by flowing the product at the demand of the customer." Lean manufacturing or lean production, which is often known as "Lean", is a production practice that considers the expenditure of resources for any goal other than the creation of value for the end customer to be wasteful, and thus a target for elimination. Working from the perspective of the customer who consumes a product or service, "value" is defined as any action or process that a customer would be willing to pay for. Basically, lean is centered on creating more value with less work.


Traditional Production vs Lean Manufacturing


Lean manufacturing concepts were developed over the last five to six decades, primarily in Japan, particularly for the Toyota production system. These concepts met various tests for many years and passed the test of time very easily.


Lean manufacturing revolutionaries the manufacturing process. It was not a fine tuning of the existing manufacturing processes. These manufacturing techniques are conceptually different from the traditional process. For an example, traditional manufacturing works based on inventory. But lean manufacturing questions the role of inventory and defines as a waste it self and also as the reflector of the imperfections a system has. This example, itself shows the conceptual difference between the traditional manufacturing system and lean manufacturing system.
