SHINGO, 1985

Single-Minute Exchange of Die (SMED) , a technique used to reduce the equipment setup time. SMED had an objective to accomplish setup times in less than ten minutes, the number of minutes are expressed by a single digit. Not all setups could be literally reduced to this time, between one and nine minutes and this is the goal of the SMED methodology (Shingo, 1985). SMED, also known as Quick Change over of Tools

Managing efficiency in work area is important to business in more ways than one. The management, care, and servicing of facilities and equipment needs careful attention and thorough implementation to achieve desired results. Delays due to downtime, readjustment, and setup are common occurrences during machine failures and breakdowns.

Walter Shewhart

The pioneering statistician who developed statistical process control in the 1930’s ,referred to as the Shewhart cycle. PDCA (Plan-do-check-act) is an iterative four – step problem-solving process typically used in business process improvement. It is also known as the Deming cycle, Shewhart cycle, Deming wheel, or plan-do-check-act.

PARETO DIAGRAM

Alfredo Pareto (1848-1923) conducted extensive studies of the distribution of wealth in Europe. He found that there were a few people with a lot of money and many people with little money .this unequal distribution of wealth became an integral part of economic theory .Dr Joseph juran recognized this concept as a universal that could be applied to many fields.

The pareto diagram is a graph that ranks data classification in descending order from left to right

DEMING

W.edwards deming, PhD was a protégé of shewart .in 1950, he thought statistical process control and importance of quality to the leading CEOs of Japanese industry .he is credited with providing the foundation for the Japanese quality miracle and resurgence as an economic power. Deming is the best- known quality expert in the world. He has the authored a number of books including out of the crisis of the quality,  productivity.

TAGUCHI

Genichi taguchi, PhD, developed his loss function concept the combines cost, target, and variation into one metric .because the loss function is reactive, he devoloped the signal to noise ratio as proactive equivalent

Manikandan T and Senthil Kumaran S

Manikandan and Senthil Kumaran focused on reducing the Manufacturing Lead Time in a production layout of an engine valve manufacturing company. The layout experienced problems like high inventory, higher setup time and more part travel, etc. A six sigma tool, DMAIC was used to approach the problem. Details with regard to Product mix, Volume of production, Work – In – Progress(WIP), and Sequence of operations were collected. And a simple heuristic technique was proposed to decrease the Manufacturing Lead Time and the approach was validated using WITNESS, a simulation software. The simulation of the proposed heuristic technique in WITNESS software showed considerable reduction in Work – In – Progress (WIP) and thereby resulted in monetary benefits. When this proposed heuristic technique was implemented, the situation demanded a lean tool, Eliminate – Combine – Rearrange – Simplify (ECRS). In total, the setup time for a particular process step reduced from the existing 20 hours per month to 6 hours per month
