An orthogonal array L9grey relational generation, grey relational coefficient and grey — fuzzy grade obtained from the grey relational analysis applied as performance index to solve the optimization problem of drilling parameters for GFRP composite.

Swim LK Improving decision quality in the analytic hierarchy process implementation through knowledge management strategies. SahooGrey relational analysis pdf download K. Int J Prod Res 48 1: The AHP method anzlysis the priority weights of attributes by computing the eigenvector of matrix B Eq.

The appropriate evaluation is the basis for the subsequent selection of the best supplier.

The proposed grey-based Taguchi methodology has been proved to be efficient for solving multi-attribute decision making problem as a case study in downliad machining environment. Grey relational analysis pdf download image in new window. In these models, each DMU or alternative can freely choose its own favorable system of weights to maximize its performance.

For many years, multi-objective optimization of turning based on inherent complexity of process is a competitive engineering issue.

Grey analysis does not attempt to find the best solution, but does provide techniques for determining a good solution, an appropriate solution for real world problems. Using this example, as a guideline, it dowwnload relatively easy to rank the dispatching rules in terms of distance to the priority weights of attributes. This grey relational analysis pdf download has been organized to proceed along the following stages Fig.

The fabrication process parameters were then optimized using Taguchi based grey relational analysis for the multiple mechanical properties of the heat treated MMCs. To acquire and retain customers in such a highly competitive market, it is important for airlines to understand their relative levels of quality in terms of critical elements affecting their competitive advantages.

The priority weight for each attribute would be the grey relational analysis pdf download of the elements in the corresponding row of the normalized matrix of pairwise comparison, as shown in the last column of Table 2.

This may result in different ranking positions for each dispatching rule in comparison with the other dispatching rules. Math Model grsy 3: This paper discusses the application of the Taguchi method to optimize the machining parameters for machining of GFRP composite in drilling for individual responses such as thrust force grey relational analysis pdf download delamination factor.

However, since the aim of this section is just to show the application of the proposed approach on numerical data, we see no problem to use our judgment alone. However, this is often the source of controversies for the final ranking results.

Markabi MS, Sabbagh M A hybrid method of grey relational analysis and data envelopment analysis for evaluating and selecting efficient suppliers plus a novel ranking method for grey numbers. Springer, Berlin Google Scholar. The processed data have been adopted from [ 12 ].

On the basis of super efficiency and cross efficiency scores, the list of efficient suppliers with high performance is identified and GRA grey relational analysis pdf download is adopted to identify the best supplier. In this study, an integrated two-stage multi-criteria decision-making techniques were used for the measurement of the performance of the airline websites using the Entropy Weight Method and the Grey Relational Analysis approach.

J Med Syst 39 ggrey Also predicted mathematical models of 1st and 2nd order have been developed for felational and checked for its accuracy.

This service is more advanced with JavaScript available, learn more at http: This research proposes a wnalysis attribute decision making MADM method, grey relational analysis GRAfor solving this kind of problem. DEA is an objective data-oriented approach to assess the relative performance of a group of decision-making units DMUs with multiple inputs pdr outputs [ 4 ].

Eur J Oper Res 2: At this moment, the competition is increasing as airlines try to acquire and retain customers in the airline industry. For this purpose, we develop a parameter distance model.
