assessing financial performance is one of the most important in functional domains, because financial information is considered for the basis of making decisions. organizations use various indexes for assessing performance in quantitative techniques. although these sorts of assessments provide useful information, but the comprehensive concept will never be concluded because of considering all t...

This paper introduces a study on multi-objective optimization of dressing parameters in internal grinding SKD 11 tool steel using Grey based Taguchi method. The L27 orthogonal array the method was selected to design experiments. input process are depth fine, time fine dressing, coarse non-feeding and feed rate. output factors surface roughness (SR) material removal rate (MRR). A grey relation g...

The paper describes the multi-objective optimization of hole sinking electrical discharge micromachining (HSEDMM) process considering material removal rate (MRR), tool wear rate (TWR), and hole taper (Ta) as objectives simultaneously. The micromachining parameters considered in the present work are gap voltage and capacitance of capacitor. Eighteen set of experiments are conducted as per L18 or...

Abrasive machining is one of the most non-conventional processes for finishing. It is widely used in industry to machine the materials like mild steel, aluminum, copper, titanium, glass, hard rock material, graphite, composite material, ceramics etc.Like in abrasive jet machining. This technique uses jet which contains abrasive material. Now a day water-magnetic abrasive machining is one of the...

The proposed framework in this paper tries to explain that how to integrate the design of experiment (DOE) tools with the principal component analysis (PCA) and grey relational analysis (GRA) techniques, such that which gives the best optimal results for the multi-performance characteristics (MPC’S) i.e material removal rate (MRR) and surface roughness (SR) of powder mixed electrical discharge ...

Undesired wall thickness distribution and flanging cracking easily occur in reverse drawing–flanging combined processes of steel spokes when improper process parameters are used. Thus, based on GRA (grey relational analysis) and FEM (finite element method), a GRA model for a reverse drawing–flanging combined process for high strength steel B550CL spoke was established and validated. The results...

Based on the set of an indicator system and the grey relational analysis model, the regional technology innovation ability of China is evaluated. It shows that the regional technology innovation ability of China is improving gradually; the level of technology input and the environment of technology innovation are promoting the development of the technology innovation ability of China, the level...

This paper constructs a four factors theoretical model of Chinese small and medium enterprises based on the “cartoon characters’ reputation enterprise marketing and management capabilities – protection of the cartoon image institutional environment” by literature research, case studies and investigation. The empirical study show that the greatest impact on current merchandising rights income is...

project selection is considered as an important problem in project management. it is multi-criteria in nature and is based on various quantitative and qualitative factors. the main purpose of this paper is to present a new rank-based method for project selection in outranking relation. according to this approach, decision alternatives were clustered in the concordance matrix and the discordance...
