This paper presents the use of the Taguchi-regression method in developing the optimal plasma transferred arc welding (PTAW) process for obtaining high hardfacing quality characteristics. An “optimal” process means that the best performance characteristic would be produced while the least number of process parameters are involved. In the experimental tests, the surface hardening process is cond...

This paper presents a novel, general and intelligent approach to multiresponse process optimisation, whose purpose is to obtain a single optimum setting of process parameters that meets specifications of all considered, possibly correlated, responses. The approach is based on Taguchi quality loss function, multivariate statistical methods: Principal componenet analysis and Grey relational analy...

The objective of robust design is to optimise the mean and minimize the variability that results from uncertainty represented by noise factors. The various objective functions and analysis techniques used for the Taguchi based approaches and optimisation methods are reviewed. Most applications of robust design have been concerned with static performance in mechanical engineering and process sys...

An effective approach for optimizing the rotor contour variable reluctance (VR) resolver is presented. Using this approach, procedure divided into two parts: establishment of initial shape curve, and then computation optimization. In order to simplify process former, a function constructed. And latter carried out by Taguchi optimization method finite element (FEM). example 3–10 VR used present ...

In recent years, determining the best supplier has become a key strategic consideration in the competitive market. Since the decision commonly involves evaluating different criteria or attributes, supplier selection process is a multiple criteria decision-making (MCDM) problem. This study integrates the Taguchi loss function, analytical hierarchy process (AHP) and multi-choice goal programming ...

In his pioneering work on product and process improvement, Taguchi (1986) emphasizes two types of factors that effect product quality: “control factors” are those variables that can be (easily) manipulated by the manufacturer and “noise factors” are those variables that represent either different environmental conditions that affect the performance of a product in the field or (uncontrollable) ...

Every day scientists are developing new materials and for each new material, we need economical and efficient machining. Turning process is the one of the methods to remove material from cylindrical and non-cylindrical parts. Stainless steel is a widely used material in day to day applications. This paper deals with the optimization of turning process by the effects of machining parameters appl...

In order to be competitive in the semiconductor manufacturing industry, quality improvement and yield enhancement have received increasing attention. The research focuses on the molding process of Integrated Circuit (IC) assembly. The defects often occurred in molding process include hole, vein, crack, and floss. In order to raise the yield of molding process, the study applies the Taguchi meth...

To solve the problem of great number of test cases, and to force the configuration testing to be effective, combinatorial testing is proposed, using an Orthogonal Array Testing Strategy (OATS) as a systematic, statistical way of testing pair-wise interactions. This combinatorial approach to software testing uses models to generate a minimal number of test inputs so that selected combinations of...

Nutrient load reduction is a well-recognized requirement for aquatic ecosystem restoration. However, decision making is difficult due to challenges related to uncertainty and the interaction between decision makers and modelers, including (a) the quantitative relationship between risks arising from different aspects and the fact that cost is not usually revealed and (b) the fact that decision m...
