Summary on Lean Tools Implimentation Kaenat T. Shaikh Lecturer, Mechanical Engineering Viva College of Diploma Engg & Technology Virar, Maharashtra, India Email : kaenat.shaikh@gmail.com Abstract :The concept of lean manufacturing was developed by Shigeo Shingo and Taiichi Ohno for maximizing the resource utilization by reducing wastes. Several papers have been published on various methodologies for implementation of lean strategy .Literature survey on LM identify several tools and techniques of LM like TQM,VSM,JIT,KAIZEN,KANBAN, 5S etc. It is established in the literature survey that during the implementation of LM, the industries faced various bottlenecks which affects the performance of industry .Value adding process is necessary…show more content…
In order to make a move in the direction of improvement early, Japanese leaders such as Shigeo Shingo and Taiichi Ohno devised a new disciplined, process-oriented system which is known today as “Toyota Production System” or “Lean Manufacturing”. Lean Manufacturing is considered to be a waste reduction technique as suggested by many authors, but in practice lean manufacturing maximize the value of the product through minimization of waste. Lean principles defines the value of the product/service as perceived by the customer and then making the flow in-line with the customer pull and striving for perfection through continuous improvement to eliminate waste by sorting out Value Added activity(VA) and Non- Value Added activity(NVA). The sources for the NVA activity wastes are Transportation, Inventory, Motion, Waiting, Overproduction, Over processing and Defects. The NVA activity waste is vital hurdle for VA activity. Elimination of these wastes is achieved through the successful implementation of lean elements. Various Survey demonstrate that most of the researcher focus on one or two elements for finding out the existence of wastes and suggest their views on implementing these…show more content…
In case of before LP is implemented, VSM mapping is used to identify sources of waste and to discover the proper lean tools for reducing the waste. A later map is then established to emphasize the improvement in the area where lean tools are applied.5S is equally implemented in both technical and non technical organization for improving performance and positive results are achieved. The objective of JIT production is to produce and transport just what is needed, just when it is needed, in just the amount needed, within the shortest possible lead time .The real JIT capability is achieved when the products delivered have actually been manufactured in response to customer demand not just delivered from stock. Kanban is an effective tool to support the running of the production system as a whole. In addition it is an outstanding way for promoting improvements because it reduces the number of job cards in circulation in highlighted problem areas. Single Minute Exchange of Dies
