Taguchi Methods for Achieving Quality INTRODUCTION The term Taguchi Methods refers to a collection of principles which make up the framework of a continually evolving approach to quality. Taguchi’s approach can be broken down into a few different steps. These steps include problem formulation‚ experimental planning‚ experimental results and confirmation of the improvement. This is essentially a closed loop process as shown in figure 2. If the objective is not met‚ the procedure must begin

Taguchi Loss Function: Aims to capture the loss to the customer‚ company and society that can be measured in cost Taguchi loss function is a diagram of the loss for the company that actual results differ from a target value. Taguchi loss function is intended to capture not only the loss to the customer‚ but to society and society at large which can be measured by cost. The loss function is not to grasp what cannot be quantified. For that reason the loss of function includes increased pollution as

Application of ‘Taguchi Design’ for ‘Reducing serving time of KFC’ Abstract- This case study is showing the application of Taguchi Design for optimizing the servicing time of KFC and to identify the best parameter setting. After observing the processes and understanding the basics‚ I came out with 3 factors viz. Logistics‚ Oil Change and Time to Serve. Here I have used L9 Taguchi Design for experimentation with the help of Minitab software

experiments via Taguchi methods: orthogonal arrays Introduction The Taguchi method involves reducing the variation in a process through robust design of experiments. The overall objective of the method is to produce high quality product at low cost to the manufacturer. The Taguchi method was developed by Dr. Genichi Taguchi of Japan who maintained that variation. Therefore‚ poor quality in a process affects not only the manufacturer but also society. He developed a method for designing experiments

specifications. Determine the Taguchi loss function for this situation. Answer 7. The Taguchi Loss Function for PlataLimpia‚ Inc. part is: L(x) = k (x - T)2 $15 = k (0.025)2 k = 24000 L(x) = k (x - T)2 = 24000 (x - T)2 8. A team was formed to study the dishwasher part at PlataLimpia‚ Inc. described in Problem 7. While continuing to work to find the root cause of scrap‚ they found a way to reduce the scrap cost to $10 per part. a. Determine the Taguchi loss function for this situation

TAGUCHI LOSS FUNCTION EXAMPLE PROBLEMS 1. A blueprint specification for the thickness of a dishwasher part at Partspalace‚ Inc. is0.325 ± 0.025 centimeters (cm). It costs $10 to scrap a part that is outside thespecifications. Determine the Taguchi loss function for this situation. 2. A team was formed to study the dishwasher part described in Problem 1. Whilecontinuing to work to find the root cause of scrap‚ they found a way to reduce the scrapcost to $5 per part. a. Determine the Taguchi loss

engineering because it helps us get to the desired solution of our problem by using the shortest amount of steps while still keeping a very high standard of safety and quality. The purpose of this project was to become familiar with DOE‚ and with the Taguchi method of predicting results‚ and also to be able to apply it for real life situations. The project consisted in selecting 4 factors at 3 levels that would affect our results. The degrees of freedom were then calculated and an appropriate orthogonal

the present and future needs of the customer. For Feigenbaum (1983) quality is to do with the combined product characteristics of engineering and manufacture that determine the degree to which the product will meet the expectations of the customer. Taguchi (1986) defines quality as the loss a product causes society once it has been shipped‚
