Recently, Taguchi methods have become very popular among industries worldwide. Begins by reviewing the past discussion on quality engineering from viewpoints of Taguchi himself, practitioners and academic scholars. The weakness of Taguchi's approach in quality engineering is not in the statistical analysis aspect. Posits that, on the contrary, it provides a way of thinking that emphasizes a philosophy of freely using the methods of design of experiments to solve engineering problems. States that, in this regard, quality engineering will be further empowered via the aid of various engineering techniques. Proposes, based on these kind of thoughts, two directions for evolution of quality engineering.

“…Despite the successful applications of the Taguchi method, a wider use of the approach and its associated techniques is only possible by gaining a better understanding of the method and its analysis. The successes and failings of the Taguchi approach to parameter design have been widely discussed (Nair, 1992;Lochner, 1991;Pignatiello and Ramberg, 1991;Antony, 1996). In summary, Taguchi's main successes have been to emphasise the importance of quality in design and to simplify the use of experimental design as a general purpose tool for quality engineers.…”

Dr Taguchi is a Japanese engineer and an international quality consultant who has made breakthrough improvements in product and process quality through the use of statistical design of experiments (SDOE). The Taguchi method became popular in the West in the 1980s as a means to design robust products and processes. Although many companies and industries have used the method with success, the real benefits of the approach were not realised and fully understood in many cases. This lack of success could be attributed to a number of factors, but mainly because the experiments were treated in isolation and not integrated into a continuous improvement strategy. This paper briefly presents the results of the application of the Taguchi methodology in the UK industry. The paper also illustrates the application of the Taguchi method for optimising the production process of retaining a metal ring in a plastic body in a braking system.

“…Although the number of experiments designed by Taguchi DOE technique is pretty less in comparison the technique is mostly condemned for the difficulty in accounting for interactions between parameters. Moreover, the method does not exactly indicate the degree up to which a parameter affects the performance characteristic value [29]. These issues can be mastered by applying a D-optimal design [30].…”

The paper focuses on developing a novel decision-making model, to select the best welding parameters for friction stir welding of dissimilar aluminium to copper plates. A set of 21 experiments are carried out based on a d-optimal design matrix. Apart from considering the rotational speed and traverse speed as input variables, the position of aluminium and copper either in the advancing or retreating side is also considered as an input variable. On the successful fabrication of joints, the ultimate tensile strength, elongation, hardness and impact energy are estimated experimentally which are considered as performance parameters. The proposed decision-making process is categorized under multi-criteria decision-making (MCDM) methods. In the first phase, the novel MCDM model is applied to select the best welding parameters. The concept of the model is to minimize the risk of not attaining the global best result. The results obtained by the MCDM method is justified by carrying out a sensitivity analysis and finally validated with the results obtained from the fuzzy logic decision-making approach. The second phase is related to the computation of optimized values for the joining process that reports the development of a mathematical model by response surface methodology to predict different performance parameters. This is followed by conducting a trade-off analysis by developing a multi-objective response surface methodology (MORSM) that computes the optimal welding parameters. Finally, a confirmatory test is carried out for validation of the proposed MORSM model.
