A new heuristic solution procedure for the solution of the rectilinear Steiner problem is proposed. The procedure is based on an innovative neighborhood structure that is explored using a pseudo-greedy approach. The probabilistic rules designed to induce search diversification are based on move attributes derived from the neighborhood structure. A Taguchi design of experiments is used to find t...

The purpose of this paper is to present an integrated approach for improving the quality characteristics of the injection molded part (Honda Upper Part) being manufactured at manufacturing industry (Pakistan), where the rejection rate for Honda upper part was on ramp due to sink marks defects. The proposed integrated approach embraces the concept of Design of Experiments (Taguchi Approach) and ...

introduction: we investigated the characteristic of a suitable irradiation on skin's tensional strength using design of experiments (doe). the experiments in this research are designed in two phases and data envelopment analysis (dea) is used for performance measurement of each phase. material and methods: samples were provided from pleura as surface tissue made of collagen and elastin fib...

background: phenol, as a pure substance, is used in many fields because of its disinfectant, germicidal, local anesthetic, and peptizing properties. aqueous solutions of phenol are produced as waste in industries and discharged into the environment. therefore, elevated concentrations of phenol may be found in air or water because of industrial discharge or the use of phenolic products. method: ...

The concept of signal (S) to noise (N) ratios has high visibility in design of experiment circles due to the work of Taguchi and his disciples. In this paper we will look into one of the signal to noise ratios and provide an answer to the question of “How large the ratio should be to call it a significant signal?” INTRODUCTION The first step of this paper will be to define terms that are used i...

The control of FOPD (first order plus delay) systems with high normalized time (ratio of time delay and time constant) is a very hard task, especially when the system parameters are subjected to variations. A great number of physical systems show such model behavior. In process control today, proportional integral derivative (PID) (continuous and digital) controllers still predominate and are s...

The current experimental study is to investigate the effects of process parameters (cutting speed, feed rate and depth of cut) on performance characteristics (surface roughness, machining force and flank wear) in hard turning of AISI 4340 steel with multilayer CVD (TiN/TiCN/Al2O3) coated carbide insert. Combined effects of cutting parameter (v, f, d) on performance outputs (Ra, Fm and VB) are e...

Cloud Computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources. Cloud Computing users prefer not to own physical infrastructure, but instead rent Cloud infrastructure, a Cloud platform or software, from a third-party provider. Sometimes, anomalies and defects affect a part of the Cloud platform, resulting in degradat...

In recent years, honeycomb fiber reinforced plastic (FRP) sandwich panels have been increasingly used in various industries. Low weight, low price and high mechanical strength are the benefits of these structures. However, their mechanical properties and behavior have not been fully explored. The objective of this study is to conduct a combined numerical-statistical investigation of honeycomb F...

This paper reviews the application of two analytical tools namely Artificial Neural Network (ANN) and Taguchi based design of experiment in the field of polymer matrix composite. These two tools are used extensively to predict the tool wear, fatigue life etc., during machining operation.
