Abstract Machinability and optimization are the two objectives of researchers who guide us to enhance manufacturing industry. Examining analyzing parameters such as surface roughness, tool wear, cutting force during processing would be beneficial that used in various fields industires. This study examined effect forces roughness on material surface. Experimental studies were carried out by usin...

The research scope of grey relational analysis has not been developed in recent years, and the exiting GRA models are all based on three perspectives, including distance perspective, slope perspective, and area perspective. Under this situation, a novel model called grey relational analysis based on angle perspective (GRAAP) was developed in this paper for the first time, and this model can exp...

in the science of operation research and decision theory, selection is the most important process. selection is a process that studies multiple qualitative and quantitative criteria, related to the science of management, which are mostly incompatible with each other. the multi criteria selection of a renewable energy portfolio is one of the main issues considered in multi criteria literature. i...

Titanium alloys are extensively used in aerospace, missiles, rockets, naval ships, automotive, medical devices, and even the consumer electronics industry where a high strength to density ratio, lightweight, corrosion resistance, resistance temperatures important. The machining of these has always been challenging for manufacturers. This article investigates combined effect radial depth, cuttin...

Euro-6 norms for reduction of CO2 emissions and ECE-R66-01 regulation safer passenger transportation became legislative obligations bus builders. These two adaptations increase the weight a as nearly 600kg which also increases fuel consumption 1.5-3%. Dual phase (DP) steels can compensate these by decreasing thickness components. Because, ferrite provides steel with good formability martensite ...

In this study, the influence and optimization of the factors of a non-formaldehyde resin finishing process on cotton fabric using a Taguchi-based grey relational analysis were experimentally investigated. An L27 orthogonal array was selected for five parameters and three levels by applying Taguchi's design of experiments. The Taguchi technique was coupled with a grey relational analysis to obta...

The performance assessment of professional baseball starting pitchers is considered a multi-attribute decisionmaking (MADM) problem. This study develops an evaluation model based on the analytic hierarchy process (AHP) and grey relational analysis (GRA) to evaluate starting pitcher performance for teams of the Chinese Professional Baseball League. The AHP is used to determine attribute weights,...

The present study aimed to optimize the process parameters (milling depth and advanced speed) for an asphalt milling operation using a multi-response approach based on Taguchi design of experiments (DOE) Grey Relational Analysis (GRA). Nine simulations tests were conducted Discrete Element Method (DEM) in order determine forces acting cutting tooth support tip. considered performance characteri...
