Abstract


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


Keywords: Lean, Plan- Do- Check- Act (PDCA), Just in Time(JIT)


Concept of Lean Manufacturing:


Lean Manufacturing is "A systematic approach toidentifying and eliminating waste through continuous improvement by flowing theproduct at the demand of the customer." Lean manufacturing or leanproduction, which is often known as "Lean", is a production practicethat considers the expenditure of resources for any goal other than thecreation of value for the end customer to be wasteful, and thus a target forelimination. Working from the perspective of the customer who consumes aproduct or service, "value" is defined as any action or process thata customer would be willing to pay for. Basically, lean is centered on creatingmore value with less work.


Traditional Production vs Lean Manufacturing


Lean manufacturing concepts were developed over the lastfive to six decades, primarily in Japan, particularly for the Toyota productionsystem. These concepts met various tests for many years and passed the test oftime very easily.


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