In this paper, the aerodynamic shape optimization problems with uncertain operating conditions have been addressed. After a review of robust control theory and the possible approaches to take into account uncertainties, the use of Taguchi robust design methods in order to overcome single point design problems in aerodynamics is proposed. Under the Taguchi concept, a design with uncertainties is...

Orthogonal function approach (OFA) and the hybrid Taguchi-genetic algorithm (HTGA) are used to solve quadratic finite-horizon optimal controller design problems in both a fuzzy parallel distributed compensation (PDC) controller and a non-PDC controller (linear state feedback controller) for Takagi–Sugeno (TS) fuzzy-model-based control systems for dynamic ship positioning systems (TS-DSPS). Base...

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...

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...

This paper adopts Taguchi's signal-to-noise ratio analysis to optimize the dynamic characteristics of a SAW gas sensor system whose output response is linearly related to the input signal. The goal of the present dynamic characteristics study is to increase the sensitivity of the measurement system while simultaneously reducing its variability. A time- and cost-efficient finite element analysis...

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...
