Taguchi method has been widely used for parameter design in many industrial applications. Nevertheless, it has been the subject of discussion and much debate in different platforms. This research proposes an extension to ongoing research by investigating the alpha error of Taguchi method with two-, three-, and four-level orthogonal arrays (OAs) for the nominal-the-best (NTB) type quality charac...

Shifted-Chebyshev-series approach (SCSA) and hybrid Taguchi-genetic algorithm (HTGA) were integrated into a Takagi-Sugeno (TS) fuzzy model nonlinear human immunodeficiency virus (HIV) dynamics. Since only the algebraic computations in SCSA were applied in the TS fuzzy model-based dynamic equations, the proposed model simplified the problem by transforming it into a static optimization problem r...

in this paper, the possibility of using a new ordered nanoporous carbon as a new fiber in headspace solid phase microextraction (hs-spme) to determine of mononitrotoluenes (mnts) in waste water is demonstrated. the structural order and textural properties of the ordered nanoporous carbon were studied by x ray diffraction (xrd), scanning electron microscopy (sem) images and nitrogen adsorption i...

The Taguchi design of experiments (DOE) approach is adopted here to evaluate the impact ofeffective factors such as nanoparticles type, nanoparticles to model solution mass ratio, asphaltenestructure, and temperature on asphaltene adsorption equilibrium. Herein, the toluene-asphaltenesolution model is applied. Three commercially nanoparticles (SiO2, Al2O3, and TiO2) are used.<...

Original scientific paper The present work aims at obtaining parametric combination to achieve the best surface finish and assess effects of selected process parameters on a laser cut quality for laser cutting. This helps to study the variation in response parameter (Ra value) for various levels of selected process parameters. In the present work mild steel specimen is used and the effect of th...

In this paper, factorial design experiments and Taguchi methods have been used to monitor the quality of the incoming raw material, product quality during processing, and the final product quality of a process industry. The data collected and results obtained are presented and discussed. The analysis made on the experimental results provided information to improve the quality of the process ind...

Process optimization is one of the most important activities in todays competitive industries. the rather high cost of research and development has necessitated the development of experimental methods by which the factors affecting processes could be determined with minimum number of experiments. Over the last two decades, various types of experimental designs have been used. Among the differe...

A hybrid sliding level Taguchi-based particle swarm optimization (HSLTPSO) algorithm is proposed for solving multi-objective flowshop scheduling problems (FSPs). The proposed HSLTPSO integrates particle swarm optimization, sliding level Taguchi-based crossover, and elitist preservation strategy. The novel contribution of the proposed HSLTPSO is the use of a PSO to explore the optimal feasible r...

Many manufactured products require machining at some stage of their production sequence. Generally, machining ranges from relatively rough cleaning of castings to high-precision micromachining of mechanical components that require narrow tolerances. It is estimated that of all machining processes about 40% pertain to turning. Turning is the most common way for processing rotational (symmetrical...

The goal of this paper is to perform complex assembly tasks, using a robot assisted by a multi-axis vibrator that reduces friction and avoids jamming. An experimentbased approach using the Taguchi Method is applied to the tuning of the vibrator. The vibrators are tuned so that effects of friction and stick-slip can be minimized. Using actual assembly data and an experimental analysis method, ca...
