Purpose – To solve the trade-offs between marketing and R&D domains and to minimize information loss in new product development (NPD), this study proposes an integrated design process as a new solution to the interface system between the two domains. Design/methodology/approach – House of Quality integrated with multivariate statistical analysis is used for determining important design features...

Conventional machining is a form of subtractive manufacturing, in which a collection of material-working processes utilizing power-driven machine tools are used to remove undesired material to achieve a desired geometry. This paper presents an approach for comparison between turning center and vertical machining center by optimization of cutting parameters at cylindrical workpieces leading to m...

Robust design uses the parameter design approach of Genichi Taguchi to optimize designs of products and processes with the objective of building in insensitivity to noise. Noise is any kind of uncontrolled variation in the environment of operation of the product or process that could affect performance. If we recognize how variation in the environment (e.g., energy source, raw materials, heat a...

The specific effect of chemical and physical factors on amidase production from Geobacillus subterraneus RL-2a was investigated using design of experiments (DOE) methodology. The one-factor-at-a-time (OFAT) method was used to study the effects of carbon and nitrogen sources on amidase production. Subsequently, optimal levels of physical parameters and key media components, namely temperature, p...

Along with the widespread use of Taguchi methods in product design, deenition of the loss function has been integrated with numerous models which require quality cost estimation. In this paper, the economic-statistical design of a variable sampling X-bar control chart is extended using the Taguchi loss function to improve chart eeectiveness from a quality cost point of view. The eeectiveness of...

background:the dynamic binding capacity (dbc) of a chromatography matrix in protein purification is the amount of the total protein absorbed into the matrix, before occurrence of a significant break in the breakthrough curve. optimization of the process criteria for maximum dbc avoids extra process scale-up and reduces the processing time, costs and protein loss. taguchi method is a simple usef...

The multiobjective design of digital filters using the powerful Taguchi optimization technique is considered in this paper. This relatively new optimization tool has been recently introduced to the field of engineering and is based on orthogonal arrays. It is characterized by its robustness, immunity to local optima trapping, relative fast convergence and ease of implementation. The objectives ...

The theoretical foundations of Taguchi Methods were laid out by Genichi Taguchi, a Japanese engineer who began working for the telecommunications company, ECL (Electrical Communications Lab, a part of NT&T), in 1950’s. After World War II, his team was involved in the design of telephone system components, and successfully produced designs that performed better than their main rivals, Bell Labs,...

in this research work with the aid of tagouchi experimental design and rawing of interaction curves with minitab software, the best rotor speed and dump temperature of mixing for physico-mechanical and rheological properties of the rubber compound with three mixing steps was obtained. moreover by plotting the mean curves in excel worksheet, the dependency of properties on rotor speed, dump temp...
