The aim of this research is to investigate the optimization of cutting parameters (cutting speed, feed rate and depth of cut) for surface roughness and metal removal rate in turning of AISI 8620 steel using coated carbide insert. Experiments have been carried out based on Taguchi L9 standard orthogonal array design with three process parameters namely cutting speed, feed rate and depth of cut f...

Work safety represents a complex systems-phenomenon and should be analyzed with systematic approaches. Hierarchies are fundamental in the study of complex systems. By integrating Grey Relational Analysis and Interpretive Structural Modeling, this paper proposes a quantitative approach which permits an automatic development of the graphic hierarchy of accident factors on the basis of their behav...

The main objective of the paper is to propose generalized neutrosophic soft multi criteria decision making based on grey relational analysis. The concept of generalized neutrosophic soft sets has been derived from the hybridization of the concepts of neutrosophic set and soft set. In this paper we have defined neutrosophic soft weighted average operator in order to aggregate the individual deci...

In order to be competitive in the semiconductor manufacturing industry, quality improvement and yield enhancement have received increasing attention. The research focuses on the molding process of Integrated Circuit (IC) assembly. The defects often occurred in molding process include hole, vein, crack, and floss. In order to raise the yield of molding process, the study applies the Taguchi meth...

An evaluation index system was constructed for the coupling between urbanization and farmland resources, based on data from 31 provinces in the mainland of China. Using the Grey Relational Analysis method, the spatial-temporal variations of the coupling between them can be revealed. The conclusions of this study were: (1) the stress of urbanization on farmland resources is dominated by economic...

In this paper, we propose an optimal network selection technique for vertical handover. The proposed technique allows mobile users to select the best access network with seamless manner and to reduce the processing delay. Thus we aim to exploit the minimum of criteria which should be used for network selection. Our optimal network selection technique combines two multi attribute decision making...

Human behavior has the positive and negative impact on ecosystem. To study the interaction between ecosystem and behavior system, per-capita energy ecological footprint (EEF) is selected as the ecosystem threshold. Elasticity coefficient of environmental investment (ECEI) and elasticity coefficient of energy consumption (ECEC) represent the positive and negative human impact on ecosystem, respe...

In the end of 1990’s, Dutch road infrastructure redesign programmer was launched for improving traffic safety. In the mean time the ongoing development in Advanced Driver Assistance Systems (ADAS) seems to offer viable alternatives. These strategies are not only to a large extent substitutes, but also partly complementary. A notorious problem is the ex-ante evaluation of these strategies. This ...

Shale gas is one of the primary types of unconventional reservoirs to be exploited in search for long-lasting resources. Production from shale gas reservoirs requires horizontal drilling with hydraulic fracturing to achieve the most economic production. However, plenty of parameters (e.g., fracture conductivity, fracture spacing, half-length, matrix permeability, and porosity, etc) have high un...
