This current research work aims at studying the influence of solid specimen dimensions such as total length, useful length, outer diameter and fillet radius on yield shear stress of mild steel (AISI 1020) in torsion testing. L9 orthogonal... more
Nickel-based alloys are attractive materials for industrial applications owing to their good mechanical properties and excellent resistance to corrosion and oxidation, even under extreme conditions. In this paper, the behaviour of an... more
Bir işletmenin finansal performansı, hem işletme hem de işletmenin paydaşları açısından, gelecekte verilecek kararları belirlemek adına önem taşımaktadır. Bu noktada finansal performansın doğru analiz edilmesi de alınacak kararları... more
Selection of the most appropriate contractor for the installation of solar panels is essential to maximizing the benefit of this renewable, sustainable energy source. Solar energy is one of the 100% renewable energy sources, but... more
Laser drilling is increasingly becoming the method of choice for precision drilling for variety of components. However, a number of defects such as spatter, recast, heat-affected zone (HAZ), and taper limit the application. Elimination of... more
This paper represents the optimization of the electric discharge machining (EDM) of Titanium alloy (Ti-6Al-4V) with a core electrode using grey relational analysis. Experimental results confirm that the electrolytic copper electrode... more
In this study, the optimization of woven fabric tensile strength with Taguchi Method based on Grey Relational Analysis was investigated. Weaving structures twill 3/1, 2/2 ve 2/1 (Z) that are the most commonly used in the textile sector,... more
The influence of the machining parameters and approach angle of carbide inserts over tool wear at the flank face, surface roughness and material re-moval rate are investigated experimentally in this work. The optimum condi-tions are found... more
In this work, effect of machining parameters cutting speed, feed rate and depth of cut, geometrical parameters cutting insert shape, relief angle and nose radius were investigated and optimized using Taguchi based Grey Relational... more
The identification of optimal processing parameters is an important practice in the plastic injection moulding industry because of the significant effect of such parameters on plastic part quality and cost. However, the optimization... more
This paper mainly deals with the evaluation of suppliers and allocating orders using hybrid multi criteria decision making such as rough set theory, analytic hierarchy process and grey relational analysis. Selection of supplier includes... more
A two-stage solution approach for solving the problem of multi-objective optimal power flow (MOPF) is proposed for hybrid AC/DC grids with VSC-HVDC. First, a MOPF model for hybrid AC/DC grids is built to coordinate the economy, voltage... more
Determining the optimal parameters setting is performed routinely in the plastic injection moulding industry as it has a direct and dramatic influence on product quality and costs. This study emphasizes on the optimization of processing... more
In this study, the effects of cutting speed, feed rate, work piece hardness and depth of cut on surface roughness and tool tip temperature in the hard turning were experimentally investigated. AISI H11 (X38CrMoV5-1) steel was hardened to... more
Purpose-The purpose of this paper is to investigate the relative influences of technical and functional quality levels of service quality and patient satisfaction. In this context, the healthcare service quality and the factors affecting... more
This paper evaluates the human resource information systems provided by different vendors using two new hybrid multicriteria decision-making methods that require ordinal data as inputs. First, the grey-point-allocation full-consistency... more
Purpose – The purpose of this paper is to analyse the relationship between outpatient satisfaction and the five constructs of healthcare projects’ service quality in Pakistan using Deng’s grey incidence analysis (GIA) model, absolute... more
Aluminium alloys are applied in various industries because of their high strength to weight ratio. Aluminium Alloy 8011 is also lightweight, corrosion resistant and has high wettability. It is being currently used in various applications... more
The use of Electrochemical Machining (ECM) as one of the best machining techniques for machining and electrically conducting tough and difficult to machine materials with appropriate machining parameters. In recent years, the utilization... more
