In-situ aluminum matrix composite is the innovation of high performance material technology and it has superior interfacial integrity and thermodynamic stability between the matrix and reinforcement. During synthesis, the ZrB2 particle is formed by exothermic reaction within the aluminum melt. As a result, small, fine and oxide free reinforcements are formed. Excessive temperature released from...

According to the qualitative safety evaluation index system of electric power communication network, it is easy to occur in the scoring problems, we put forward a kind of expert evaluation data by correlation degree, solve the problem of qualitative index difference. The method based on Relative Grey Relational Analysis on safety evaluation data, the establishment of expert evaluation of the re...

In the modern highly competitive marketplace and global market environment, product quality improvements that abridge development time and reduce the production costs are effective methods for promoting the business competitiveness of a product in shorter lifecycles. Since the design process is the best time to control such parameters, systematically designing the processes to develop a product...

Decision makers sometimes tend to express their preferences in intuitionistic fuzzy form. Based on evidence theory and grey relational analysis (GRA) technique, this paper aims at investigating multiple attribute decision making problems, in which both attribute values and weight values take the form of intuitionistic fuzzy numbers (IFNs). To this end, each intuitionistic fuzzy evaluation ratin...

Supply chain risk evaluation is a multi-criteria decision making problem under fuzzy environments. To tackle the problem, this paper firstly identifies and discusses some of the important and critical decision criteria and constructs the evaluation indicator framework. Then this paper presents a modified grey relational analysis method based on the concepts of ideal and anti-ideal points. In th...

Among the renewable sources of energy, solar energy offers a practical solution for the energy problem which is clouding the prospects of mankind. The present paper deals with the experimental investigation of parameters of a solar parabolic trough in winter conditions and to obtain optimum process parameters by Grey Relational Analysis. The experiments were planned using Taguchi’s L9 orthogona...

in the paper an attempt was made to study the performance of indian banks with the help of camel(c-capital adequacy, a- asset quality, m- management quality, e-earnings, l-liquidity i.e. camel) rating system, over the period of five years from (2011 to 2015) and then evaluated out the efficiency of banks with the help of gra (grey relation analysis) technique there by gaining confidence from in...
